A beautiful space deserves beautiful lighting. Fortunately, today’s lighting marketplace is the best it has ever been, and electricians and interior designers can find stunning fixtures with unprecedented power and quality. Before we dig into specifics, let’s review what sets architectural lights apart from the rest.

What Makes Architectural Lighting Different

Architectural lighting delivers fine aesthetics as well as performance. An architectural light is made to be seen. Its design and style match the beauty of the space—even the most impressive lobby, atrium, showroom, or c-suite boardroom. From bold sconces to minimalistic strip fixtures, these lights become integral pieces of a space’s interior design.

Of course, great architecture deserves great light, as well. The best fixtures are made with LED’s that offer powerful light (measured in lumens), fine-tuned color-corrected temperature (known as CCT, measured in degrees Kelvin), and top-rated quality (known as color rendering index, or CRI). Architectural LED lights combines visibility and ambience in ways that normal lights can’t.

High-quality architectural lighting can create a dramatic, almost theatrical, effect. The best commercial interior designs include plans for this kind of lighting. Years ago, it was difficult to procure really good architectural lights, but today there are many solutions on the market.

A good architectural light is designed for flexible mounting, as well. Often a high-end fixture needs to be mounted in an unconventional way, such as being suspended or being linked to other lights in an array. The best fixtures offer hardware to accomplish this.

To see examples of exemplary architectural lighting, check out some of the previous winners of the Lumen Awards (given by the Illuminating Engineering Society’s New York City chapter). These projects demonstrate the profound effects that good lighting can provide. Winners include the Rookery Building in Chicago, the Theatre School at DePaul University in Chicago, 155 North Wacker in Chicago, the Denver Art Museum, the Comcast Technology Center in Philadelphia, and the TWA Hotel in NYC.

Up Close: Details of an Architectural Strip Fixture

One of the most common architectural lights is the strip fixture. These LED fixtures look like long, elegant luminaire boxes that are often artfully suspended in a space. Beautiful light is cast downward—and sometimes upward, as well—providing both illumination and ambience. A good example is the Linear X, from LuXurio provided by Duralec.

This LuXurio fixture is a sleek, minimalist object that would be at home in today’s most contemporary spaces—like an Apple store or a Silicon Valley headquarters. You could also use it in a historic building as a sophisticated contrast with the surrounding period décor. The fixture’s aluminum sides are smooth and matte and come in a premium powder-coated white or black finish. Its slightly rounded corners and its balanced proportions make it one of the most beautiful fixtures available.

However, it’s the powerful LED lights within the LuXurio luminaire that are its heart and soul. The high-efficiency LED’s produce up to 1,300 lumens per foot, and optional dimming makes the fixture the perfect fit for any application, whether it’s lighting a display case of luxury watches or softly lighting a hotel lobby. The color rendering index (CRI) is best-in-class, scoring over 80.

The color-corrected temperature (CCT) is changeable, as well. The adjustable fixture can be set to 3500K, 4000K, or 5000K. The lowest CCT provides a warm and cozy feel perfect for a restaurant lounge or a museum café. The highest CCT, on the other hand, provides a bold, white light suited for offices, conference rooms, or other situations where visibility is key. The LuXurio’s fixture has a frosted lens that creates 120 degrees of optimally diffused light.

A unique feature of the LuXurio strip fixture is its options for modular connection patterns. You can combine units to form different configurations: an X-shape, a T-shape, and an L-shape. This gives designers an opportunity to create even bolder lighting designs.

A variety of mounting options makes this lighting fixture perfect for any interior design, as well. Surface mount kits allow for easily installation on ceilings or walls. Suspension kits allow for dramatic installations in large spaces such as lobbies or atriums. High ceilings allow lighting experts to design in three dimensions. Aircraft cables ensure sleek looks and strong performance.

As with most new LED light fixtures, the LuXurio Linear X offers the potential of massive savings over older technologies. The high efficiency of LED’s means up to a 75% reduction in energy use. This can lead to huge savings on energy bills, especially during times of energy price spikes. In addition to these savings, building owners benefit from lower maintenance costs, as well, due to the long lifespan of LED lights.

The fastest way to save money on building operations is most likely to install LED retrofits. Replacing outdated lighting fixtures with new LEDs creates several avenues of savings. And the return on investment is fast. Let’s summarize some of the benefits of a retrofit kit.

The Benefits of LED Retrofits

The most obvious source of savings from an LED retrofit comes from the efficiency of LED lights. New lights use up to 75% less energy. Because so much of a building’s operational budget goes toward lighting, this efficiency results in massive savings. As energy costs go up, this saving is even more important.

Savings in maintenance costs and replacement bulbs are another result of LED retrofits. LED lights can last up to 50,000 hours. This slashes the need for maintenance.

LED retrofits create higher quality light, as well. LED lights generate not only powerful brightness (measured in lumens) but also high quality light—its color rendering index (CRI) scores 80+.

Increased visibility means a safer and more secure space—whether it’s a workplace, store, hospital, school, or whatever space you’re lighting. Furthermore, the strong CRI and perfectly tuned color corrected temperature (measured in degrees Kelvin) mean a more welcoming and comfortable space. Visitors notice. Employees are happier and more comfortable, as well. This could lead to higher productivity and even improved worker retention—a major challenge, lately.

Retrofit Considerations

Before looking at a few sample retrofit kits, let’s review some of the factors one should consider when budgeting for an LED retrofit. There is a retrofit kit out there for every situation and budget.

Costs: Retrofits range in cost from simple bulb replacements to entire fixture swaps. Plug-in LED lights are available to pop directly into existing sockets or fixtures, and these replacements are the fastest and cheapest way to bring your lighting into the future. But swapping for a next-generation LED fixture might be smarter in the long run and generate more flexible lighting and even more savings.

Installation: If the budget and schedule are limited, then a simple LED retrofit can be installed in very little time. However, modifying or swapping light fixtures will take longer, especially if new wiring is required. But industry-leading LED fixtures, like ones from Duralec, come with hardware to make the job quick and easy.

Flexibility: LED retrofits promise all of the new features of today’s next-generation lighting. This includes NLC/ALC capabilities (networked lighting controls, aka advanced lighting controls) for all new fixtures. These smart features allow users to program their lights and see even deeper monetary and energy savings. New fixtures also allow for dimmable lights and a variety of sensors to be attached.

Today’s Top LED Retrofit Options

LED Strip Retrofit Lighting: The fastest, most economical retrofit available is the LED strip light. Sometimes called magnetic strip lights, or mag strips for short, these snap into place with almost no hardware. Perfect for either troffer lights or panel lights, these strip kits come in one, two, three, or four strips, creating any amount of light you need—from 3000 to over 10,000 lumens.

As with all LED lights, efficiency and quality are best in class. The low-wattage lights produce over 130 lumens per watt with a CRI of over 80. LED strips are dimmable and UL and DLC Premium listed.

The strong magnets on the strips provide for quick installation. They snap into the existing housing, and there is no need to remove the old ballast. These retrofit kits can replace T12, T5, and T8 strip fixtures and troffers.

LED Tube Replacement Lights: For decades the fluorescent tube dominated indoor lighting. Unsurprisingly, one of the most popular LED retrofits is an LED tube that directly replaces its fluorescent ancestor. The new LED tube is filled with beautifully bright light-emitting diodes and encased in a frosted coating for uniform light dispersion. An LED tube promises huge energy savings and higher-quality light with an easy installation process.

Because LED tubes fit into a wide variety of existing light fixtures, the tubes come in a few types. In short, there is a tube available for any situation. Here are the three main types: Type A LED tubes use the pre-existing ballast in a fixture. These plug-ins are the quickest to install. Type B LED tubes bypass the ballast and use their own internal driver; these are directly wired into the fixture. Type C LED tubes also bypass the ballast, but they rely on an external driver that can light more than one tube. While Type C’s require extra electrical work during installation, the long-term benefits (of direct-wire versus ballast-compatible tubes) are substantial. Using new LED lights and drivers guarantees high-quality results and the 50,000-hour lifespans that LED users have come to expect.

LED Corn Lights: If you have standard light sockets, one of the fastest retrofits available is the corn light (sometimes called a “corn cob light,” due to its resemblance to a corn cob). An LED corn light screws directly into this socket. These new lights are vastly superior to the non-LED lights they are replacing. LED corn lights deliver bright, high-CRI light at a fraction of the energy and cost of older lights.

These lights come in two base sizes: the E26 base and the E39 base. These bases are 26mm and 39mm in diameter, respectively. (The standard home socket fits an E26 base.) An E26 base LED corn light is available in wattages from 12W to 54W. An E39 base light is available in 75W to 120W sizes. Given their extremely high lumens-per-watt output—between 125lm/W and 155lm/W—LED corn lights are an amazingly cost effect LED retrofit solution.

Door Retrofit Kits: Sometimes called a troffer retrofit door kit, this solution lets you put a new LED light fixture directly over an existing troffer frame or housing. The installation is extremely fast, and the final look is flush and attractive. But most importantly, the savings start the second you turn the light on.

The top LED door retrofit kits, like the Duralec-provided IntrinsiX Volumetric Troffer Retrofit, deliver the efficiency of all LED lights while also providing next-level NLC and ALC capabilities. Bluetooth lighting controls let the user program lights to respond to a number of different sensors, including PIR (passive infrared) occupancy sensors or daylight harvesting sensors. An available web portal provides easy access to cutting-edge features like diagnostics, scheduling, and energy monitoring.

Installing door retrofit kits is a fast and easy way to implement the latest technology. DLC-listed fixtures like the EiKo retrofit reach 130 lumens per watt and have “set and forget” features for both brightness and color temperature. When tied to a Bluetooth mesh, its wireless controls make the fixture part of a network that delivers significant savings and quality.

LED Downlight Retrofit Kits: Recessed downlights are everywhere, from conference rooms to home kitchens. For decades they’ve provided the flexibility of a plug-in solution with the appeal of a flush, clean look. But there has always been room for improvement. An LED retrofit can turn a hot, energy-intensive downlight into a bright, efficient light that saves building owners a fortune over its long lifespan.

Downlight retrofits plug into pre-existing ceiling cutouts and wire into the existing 120-277V system (other voltages are available if needed). LED lights can even use the original can—the cylindrical housing—from the first fixture. There is a light to fit any aperture—the measure of the diameter of the can’s reflector. Most downlight fixtures use a common E26 socket.

A new LED downlight can be tuned to whatever brightness level or color-corrected temperature (CCT) you need. It can also be wired into the room’s networked controls, allowing it to be part of a building-wide strategy for energy savings.

LED retrofit kits are the fastest way to bring a building into the 21^st century. The kits deliver radical savings on energy and maintenance. They also improve the quality and brightness of your light and allow LEDs to be tied into networked controls. To discuss the many retrofit options out there, talk to a Duralec expert today.

Exterior lighting has undergone a revolution since the invention of LED lights. Today’s outside lights are superior in almost every way to their counterparts of only a decade ago. Users are seeing huge cost savings as well as brighter, safer environments. Whether it’s a new build or a retrofit, LED lights—shoeboxes, wall packs, floodlights, and more—are the shining answer. First, let’s review how LED lights can improve your exterior lighting.

Benefits of Exterior Lighting

Safety and Security:  The top reason to install the best LED lights is the safety of workers, residents, or visitors.

Bright and reliable light helps prevent crime in parking lots and other outdoor spaces.

This light also helps improve the effectiveness of security cameras.

Building owners benefit, as well; exterior lighting deters vandalism, theft, and other property crimes. In short, the return on investment for security lighting is beyond measure.

Good lighting and visibility can also help people avoid slips, falls, and other accidents, especially in regions affected by snow or ice.

Paths, loading areas, and parking lots that are well lit keep people healthy as well as safe and secure.

 

Better and Brighter Lights:  Today’s exterior LED lights are quantifiably better than previous technologies. Many of these older models are still around, including metal halide and high-pressure sodium lights. Simply put: LED lights provide more light for less energy. These lights come in a wide array of wattages, but, no matter the size of the LED light, it requires a fraction of the energy of an older light. This number is sometimes called the wattage replacement. For example, a 250 watt (W) metal halide light—perhaps used over an entrance or on an outside wall—can be replaced by an LED light that only uses 100W of power.

Today’s LED light fixtures are as bright or brighter than those less efficient older technologies, as well. Brightness is measured in lumens (lm), and comparing lumens per watt shows you the advantages in raw numbers. An LED light such as the IntrinsiX Comet Mini floodlight produces 6,250lm of white light while using only 50W of power (125lm/W). A comparable metal halide light might only produce 75lm/W.  

Furthermore, LED exterior lights provide the perfect brightness level and color-corrected temperature (CCT) for outdoor use. Color temperature is measured in degrees Kelvin (K). Outdoor applications usually call for a bright white light, which is often around 5,000K.

 

Cost Savings: Another major reason building owners love exterior LED lights is the savings they provide. Because these lights use so much less energy than previous types, the long-term savings of switching to LED are substantial. During times of high energy costs, this efficiency is especially valuable.

Maintenance costs are also far lower for LED lights. The lifespan of a typical LED light today is around 50,000 hours. This means that a light could potentially outlive an owner or even a building. (The reliability of these lights is reflected in the 50,000-hour Warranty offered by Duralec on its LED’s.) A long lifespan means an end to service calls. Replacing bulbs on parking light poles—the classic shoebox light—has always been a costly and annoying task. LED lights mean no more bucket trucks.

The advanced lighting controls (ALC) available today also provide a new source of savings. LED lights from Duralec come wired for these controls. The ability to program lights using ALC—sometimes called networked lighting controls (NLC)—ensures that exterior lights only come on when needed. Smart controls promise even deeper savings with LED lights.

 

Flexibility: Exterior LED light fixtures are available for every application—parking lots, entrances, loading docks, tunnels, paths, and more. A variety of adapters allows you to plug in new LED lights into existing connections. New lights use standard connections like the Zhaga Book 18 socket or  Z10 base. Numerous mounting options—pole mounts, wall mounts, trunnion mounts, knuckle mounts, and more—ensure that an LED light can go anywhere you need it.

Retrofits are easy (and profitable) with today’s LED lights. For example, the IntrinsiX corn light screws directly into a common E26 base. More powerful corn light bulbs use an easy adapter. This low-wattage light could feasibly replace an older bulb that used 1000W.

Today’s LED lights also come with strong weatherproof ratings, guaranteeing the light will work from the desert to the arctic. This rating is called the IP rating, short for ingress protection. An IP65 rating protects against the incursion of solids like dust or insects, as well as against rain and moisture. The IP66 rating goes a bit further; it protects against those solids as well as against heavy rain. Wall packs often feature an IP65 rating, while street lights or parking lot lights usually feature an IP66 rating.

 

 

The Next Generation of Exterior Lighting from IntrinsiX

Exterior lighting fixtures are getting brighter, more efficient, and more attractive every year. Below are some examples of LED lights from IntrinsiX that are revolutionizing outdoor lighting.

The Comet—The Shoebox Light of the Future

The IntrinsiX Comet is an LED parking lot or area light that combines great aesthetics and the latest technology and efficiency.

Available in 48W, 60W, and 80W, the wall-mounted LED light consumes a fraction of the energy of non-LED lights with zero flickering or humming. 

A powerful wall pack is ideal for making an area safe and secure for workers and visitors. A full cutoff shape ensures a downward light dispersion that is broad and effective. The Eclipse’s IP65 rating and long lifespan guarantee that the light stays on no matter the weather conditions. Yet another advantage is how easy it is to install. The Eclipse goes up with a basic wall mount and a 100-277V input.

 

The Eclipse Semi Cut—The Semi Cutoff Wall Pack

This semi-cutoff version of the IntrinsiX Eclipse offers all of the advantages of the full cut wall pack while giving a more forward-shining angle. The semi-cut model also offers a 100W option, in addition to 48W, 60W, and 80W.

All wattage levels deliver more than 115 lumens per watt (lm/w), meaning that the fixture is best-in-class for efficiency and cost savings.

 

The Eclipse Mini—The Small But Mighty Wall Pack

The Eclipse Mini from IntrinsiX is the perfect LED light for an entrance, a courtyard, or a pathway. Requiring only 15W, 20W, or 30W, this exterior light delivers far more lumens per watt (1,950-3,900lm/W) than its non-LED predecessors. A photocell is standard equipment, allowing the light to adjust to daylight and to turn on automatically and only when needed.

The sleek appearance of the Mini means it looks great no matter the style of the building. Its 110-degree viewing angle is optimal for attractive area lighting.

 

The SOFCAN Canopy Retrofit—Taking Your Soffit to the Next Level

The SOFCAN canopy retrofit is the kit from IntrinsiX that turns non-LED soffit lights into an attractive, efficient canopy. The large (15”x15”) beauty plates make it simple to replace older lights and to cover up the previous holes. The installation is easy, and the look is flush and seamless.

Flat-panel LED lights are quickly becoming the top choice for commercial construction. These lights provide countless benefits and are a huge improvement over the technology of only a decade or two ago. However, not all LED lights are alike. Understanding the options is key to choosing the right light for your application.

Benefits of Flat-panel LED Lights 

LED lights provide bright, energy-efficient, attractive light for any scenario, but it’s important to know how your space dictates which light is the best fit. For example, an office, a retail store, and a hospital room all need a different kind of light. The good news is that today’s LED lights can address every one of those needs. These flexibilities are explored below. For now, let’s quickly review the benefits.

Huge energy savings - Rarely does a new technology bring these kinds of improvements in addition to major cost savings. LED lights are radically more energy efficient than previous technologies, such as fluorescent, metal-halide, or incandescent lights. A flat-panel LED light can operate with up to 75% less energy than a fluorescent light fixture.

Low maintenance cost - Maintenance costs for flat-panel LED lights are also much lower than previous lights. A 50,000-hour lifespan means virtually zero maintenance costs over the life of an installation. No more burned-out lights. No more service calls. No more ladders in the way. Duralec provides a 50,000-hour Warranty, as well.

Easy installation - LED lights are also easy and quick to install. Whether it’s a recessed ceiling or a surface mount, flat-panel lights go up and plug in with ease. Additionally, the low heat output of LED lights means venting is not necessary.

Power and color - Flat-panel LED lights deliver powerful light in a range of colors. A good LED light can give you whatever light output (measured in lumens) or color temperature (measured in Kelvin) you need. Whether the light is over a hospital bed, a retail shelf, or a conference table, these LED lights can be tailored for every need.

Quality and comfort - The days of flickering lights and headaches are over, due to LEDs’ diode technology. Furthermore, LED lights are customizable in a variety of ways. Dimmer switches allow for varying brightness, and color-corrected-temperature can be changed at any time. Also, Duralec’s flat-panels have a color rendering index (CRI)—rated to 80+, guaranteeing high-quality light. These features mean an attractive space, comfortable workers, and long-term happiness among users.

Environmental benefits - LED lights offer environmental benefits beyond their huge energy savings. Unlike their fluorescent counterparts, LED lights do not contain mercury, which is toxic to humans.

Quick Definition: Flat Panels versus Troffers 

Commercial spaces like offices and retail stores usually have one of two kinds of LED lights: flat panels or troffers. The flat-panel LED is fairly self-explanatory (it’s flat, it’s a panel), and the troffer light is almost as easy to define. The word “troffer” is a mashup of “trough” and “coffer.” In a troffer light, the bulbs or diodes sit in a central trough, and the light is reflected downward by a panel above them.

Flat panels and troffers usually come in similar sizes—2x2 feet, 2x4 feet, and so on—and are mounted in similar ways. Each has its benefits, and we’ll discuss troffers at a later date.

Quick Definition (#2): Edgelit versus Backlit

Flat-panel LED lights are generally manufactured in two styles: edgelit and backlit. Edgelit panels have diodes spread around the perimeter of the light. They cast their light toward the center and rely on the lens to diffuse the light in an even way. Over time, edgelit panels can create yellow centers and appear dusty or uneven. Backlit panels, on the other hand, have diodes spread across the entire face of the panel. Backlit panels provide an even light with no danger of yellow spots.

Flexible Features of Flat Panels

Flat-panel LED fixtures come in a variety of shapes, sizes, and capabilities. One thing that sets a flat panel apart from its antiquated ancestors is its array of customizable features. In short, there is a flat-panel LED light for every application out there. Let’s explore some of the specs one might find on a Duralec-provided LED light.

Wattage: The wattage rating (measured in watts, or W) refers to the power needed to run the light at its maximum level. Not long ago, you might have had a lamp in your home with a 100W incandescent bulb in it. By comparison, a flat-panel LED light fixture might only need 30W or 40W for the entire unit because LED lights use so much less electricity than your lamp. Duralec-provided IntrinsiX’s  flat-panel LED fixtures offer selectable wattage on many units, including 20W, 30W, and 40W levels. This flexibility allows you to tailor your energy savings.

Speaking of power, IntrinsiX lights use high-quality drivers that are considered best-in-class. Drivers are usually the first thing to fail in an LED light, so it’s important to have the best driver possible. Duralec lights are DLC- and ETL-listed, as well, guaranteeing high quality and efficiency.

Voltage: Voltage is the amount of power running into the light fixture. It is measured in volts (V). Most fixtures run on standard 120V-277V wires, though larger lights can take advantage of a 277V-480V system. Duralec flat-panel LED fixtures run on common 120-277V inputs, making them easy to install and inexpensive to run.

Color temperature: This measurement refers to a light’s appearance—how “warm” or “cool” or “white” it appears. Its full name is color corrected temperature (CCT), and it’s measured in degrees Kelvin (K). Different applications call for different colors of light. A living room would want a warm light, which is slightly soft and almost yellow. An office or retail store would want a cool light, which is inviting but brighter than a warm light. A warehouse would want a powerful white light for optimal visibility.

Today’s leading flat-panel LED lights offer selectable CCT. For example, the IntrinsiX selectable-watt fixtures also offer selectable CCT, in 3500K, 4000K, and 5000K temperatures. This feature allows you to fine-tune your light for whatever application you need. This light also features optional dimming, for even more flexibility, comfort, and cost savings.

Brightness: The technical term for brightness is lumen output. Brightness is measured in lumens (lm), and it is a key number to look for when planning the lighting for a space. Brightness is not synonymous with wattage, because not all lights are made of the same quality.

Again, today’s best products offer selectable lumen output. The IntrinsiX flat-panel LED fixtures offer 2500lm, 3750lm, and 5000lm outputs. This flexibility guarantees that you have as much light as you need, as well as the flexibility to adapt to any changes that might happen to the space in the future.

Mounting options: Flat-panel LED lights come ready to be mounted in multiple ways. They fit into recessed ceilings with ease, giving a smooth and flush look. They can be mounted on surfaces with simple hardware. They can even be suspended by cables. IntrinsiX flat panels offer an ultra slim profile (1.77”) that works in every application.

Emergency backup: Commercial spaces need emergency battery backups for their lighting, and Duralec offers those for all of its LED light fixtures. 90 minutes of backup power guarantees the lights stay on if the power goes off.

Sensor options: Today’s buildings are getting smarter and smarter, and a key to this advancement is the use of sensors on light fixtures. Lighting controls can be attached to a variety of sensors, but, in general, they fall into two categories: those that sense motion or occupancy or those that sense daylight.

Sensors that detect motion or occupancy include microwave sensors. These emit high-frequency waves that bounce off of objects in a room. When there is a change in the return signal, the sensor knows that something (say, a person) is moving within the space. The sensor can then turn the light on. Ultrasonic sensors work in a very similar fashion.

Another sensor to detect occupancy is a passive infrared sensor (PIR). These sensitive devices detect heat coming off of objects in a space. When a person walks into a room, the PIR sensor “sees” the heat (i.e., senses the infrared radiation), and can turn a light on.

Sensors that detect daylight coming into a space—and can adjust light levels accordingly—are photocell sensors. These devices, also called ‘daylight-harvesting’ sensors, gather photons, determine their brightness level, and send instructions to the light fixtures. With these instructions, lights can either be turned on or off or even dimmed throughout the day to adjust to incoming light, keeping a consistent amount of lumens in a room.

Advanced lighting controls: Also called “networked lighting controls” or “smart light controls,” these devices are the next frontier of smart buildings, energy savings, and better lighting.  Combining software with building systems—lighting, HVAC, and more—is allowing building owners to realize huge savings. For example, the ability to pre-program a building’s lighting schedule or to allow automatic adjustments to factors like sunshine or remote work has created many new opportunities for efficiency. Hooking lights up to wifi or a Bluetooth mesh opens the door to a new “smart” world.

Flat-panel LED lights and networked lighting controls are revolutionizing commercial lighting.

When lights are always on, the energy costs can quickly add up, and keeping them on for too long can cause them to overheat and possibly malfunction early into their warranty period and life expectancy. To help ensure that lights are only used when necessary, LED manufacturers have developed different types of sensors that work with their line of LED products with some fully integrated into the light fixtures.

By using sensors, lights can be controlled to turn on and off in response to individual or a combination of conditions including occupancy, motion, or levels of natural light, ensuring that they are used only when they are needed, making it easier for people to move freely without having to constantly switch lights on and off, and improves safety by providing visibility in otherwise dark and empty areas. They help reduce consumption, contribute to energy savings, and help extend the lifespan of the light bulbs.

About Light Sensors

There are 2 major groups of sensors for lighting control. Sensors that detect motion and occupancy (e.g. Microwave, PIR and Ultrasonic), are intended for indoor applications. Sensors that detect natural light (e.g.Photocell and Daylight Harvesting), are intended for areas with access to natural light and outdoor applications.

Sensors are installed separately or integrated into modern LED fixtures. Sensors are available as external controllers for a network group of lights e.g. installed on the wall, ceiling or fixture or integrated into modern LED fixtures e.g. photocell sensors on wall packs. Some sensors can be set up to adjust their sensitivity depending on the traffic or availability of natural light.

Sensors can be linked to advanced network lighting controls. Sensors can be linked to a Bluetooth Mesh / NLC system that sends sensor data to other lights in a network for automated control, energy management, and rerouting, which can lead to significant cost savings over time. Read on to know more about Bluetooth Mesh / NLC and how they work together with light sensors.

Sensors also control brightness levels. Also known as "Bi-Level Lighting Controls", it allows the user to adjust the level of brightness in two ways (up/down). Traditionally, it requires an external switch or dimmer to adjust the light levels based on the time of day or occupancy. Modern LED light fixtures includes bi-level lighting controls for controlling brightness levels.

Dual-technology sensors work together for on/off and dimming control. Modern LED fixtures and external sensors combine at least two sensing technologies working together for controlling light and brightness levels e.g. PIR / Daylight Harvesting where PIR sensors control lights with movement and Daylight Harvesting sensors adjust brightness with available light. With dual-technology sensors, you can be sure that your space is always well-lit when needed, and not over-lit at all times.

Sensors are interfered by certain conditions. Sensors that automate lighting offer numerous advantages but they are not without some drawbacks. Sensors can be impeded by elements in its immediate surroundings and therefore should be installed correctly and with caution in order to function properly. Carefully consider the upsides, downsides and limitations of each type of light sensor before making a final decision.

Sensors that Detect Motion and Occupancy

Motion sensors detect movement within a space, while occupancy sensors detect presence regardless of movement. Microwave, PIR (Passive Infrared), and Ultrasonic technologies are commonly used in detecting motion and occupancy, and all three technologies are almost exclusively used indoors.

Microwave Sensors

Microwave motion sensors use high-frequency radio waves to detect movement within their detection range, and when it detects motion, the lights turn on. It is effective at short distances but can have problems with false alarms due to over-sensitivity and interference from other nearby movements and signals.

Upside:

• Can detect motion at a distance of up to 20 feet in one or all directions (400 ft²).
• Adjustable distance settings so that the motion sensor will only detect movement at certain distances.
• Microwave signals, such as those emitted from cell phones and routers, are non-ionizing forms of radiation and do not cause long-term damage to humans.

Downside:

• As a motion sensor, it can be overly sensitive and set off the lights unnecessarily when placed in areas near trees, plants, and moving machinery.
• As an occupancy sensor, it can be interfered with by continuous movements e.g. bodies of water, and ventilation fans.
• Affected by gusts of wind, rain, and extreme weather conditions.

PIR Sensors

PIR sensors, or passive infrared sensors, detect the infrared radiation emitted by objects including the human body that have a temperature above absolute zero. It is effective at long distances and has low false alarm rates but can be affected by other heat sources within the same space.

• Detects moving objects that are large enough e.g. humans to reflect sound.

Downside:

• May not work effectively in areas with high levels of background noise e.g. heavy machinery or if the motion is slow.
• May be affected by temperature variations in the environment, mostly by heat.

Sensors that Detect Natural Light

Photocell sensors detect natural light and turn light fixtures on in the daytime and off in the nighttime. Daylight Harvesting sensors detect natural light and control light dimmers to maintain appropriate light levels. Both technologies can be used in open and outdoor areas with ample daylight and help reduce energy consumption by using natural light whenever available.

Photocell Sensors (On/Off Control)

Photocell or "dusk-to-dawn" sensors are used to detect light levels and turn lights on or off in response to available natural light. When the light level is lower (i.e. at night) than a predetermined threshold, the sensor will activate a switch that turns on the lights. When the light level rises (i.e. during the day) above the threshold, the sensor will deactivate the switch and turn off the lights.

Bluetooth (BLE) Controls and Sensors for Rooms

LED lighting is the most energy-efficient and economical lighting option but it is not without issues. One of the most common issues is that one doesn’t always have the same brightness and color as the next - even when made under the same specifications. This can pose problems, particularly in settings that require a consistent and well-maintained look, such as high-end retail stores or galleries, where it is essential for presenting products or artifacts in the best light. 

Knowing how much wattage you need, how many lumens you want, and what color temperature you’d like is key to creating the exact lighting theme you have intended. Once you know exactly what you need and why, you would be able to make the right choices before rolling out the budget for new lights. With a wide variety of wattage, lumens, and color temperatures available, you can create the perfect atmosphere in any room. From energy-saving modes to dynamic scenes, explore all the possibilities at Duralec!

Choosing Wattage and Voltage

The different wattage and voltage ratings are used to ensure compatibility with the existing power supply setup of the home or building. By offering different wattages and voltages, LED light manufacturers make sure their products will be compatible with a wide variety of applications.

Knowing the Voltage AC (Alternating Current) rating indicated on LED product specifications helps determine the appropriate wattage to use. Wattage (W) refers to the power rating of a particular LED light bulb and indicates how much power is required to light the LED to its maximum brightness. Normally, a high-wattage LED bulb would be recommended for use in a high-voltage power setup. Using a high-wattage bulb in a low voltage socket can be dangerous as they draw more power than the wiring it is designed to safely handle and can cause wires to heat up and spark, potentially leading to fires.

It's imperative to always match bulbs to the watts listed on the socket and never exceed that number. If you're unsure about the wattage is best for your setup, make sure to consult an electrician.

AC 100V to 240V to 277V is commonly used in split-phase power systems and is the voltage supplied to most of the US and Canada households and retail outlet applications. LED bulbs recommended for this setup can range from 10W to 120W.

AC 277V to 347V to 400V+ is commonly used in three-phase power systems and is the voltage supplied to many industrial, commercial, and residential buildings. LED Bulbs recommended for this setup can range from 150W to 320W.

You can optionally use LED drivers (built-in or external) to provide power, regulate current, and protect against voltage spikes and surges, which can damage LEDs. Some LED strips and bulbs are self-contained and do not require an external driver.  

Choosing a Lumen Output

Remember that the Wattage rating on a bulb indicates how much energy it uses - not how bright it is. The brightness of an LED light is determined by its lumen (lm) rating. Lumens measure how much light the bulb produces; and is what you need to look for on your bulb packaging. A higher lumen rating means brighter light and greater visibility. By looking at the lumen output of different LED lights, you can make sure that you are selecting the right lighting for your space. While having a higher lumen output may mean a higher input wattage, this is not necessarily true for all LED products.

As an example, an older LED 12W bulb might produce the same amount of lumen output as a more modern 9W LED bulb. An LED bulb with the same output lumens and lower wattage is always the better option.

Choosing a Color Temperature

LEDs are also available in different color temperatures that determine the shade of color that the bulb emits and whether it leans towards warm (like golden hour),  white (like daylight), or cool (like a cloudy day). To make sure you get the perfect light for your space, always look for CCT rating of the fixture.

CCT (Correlated color temperature) is a measure of the color appearance of light, measured in degrees Kelvin (K). It is used to describe the temperature of a light source and its ability to appear white or neutral.

Warm fixtures are typically used in residential installations because they create a softer, more comfortable ambiance, often used in bedrooms, living rooms, bathrooms, and other areas that require a cozy atmosphere. Whiter and cooler fixtures are more suitable for commercial environments. Cooler lighting creates an efficient and productive atmosphere ideal for office settings or retail spaces.

Contrary to popular belief, LED lights set to warm colors do not require more energy than whiter and cooler ones so there's really nothing to worry about when choosing a warmer colored light in any setting. In fact, LEDs have an even longer lifespan when used in warm light settings and will last much longer making them perfect for a variety of applications.

Tuning Your LED Lights

How do you make sure that the brightness and color of your LED lights are consistent? LEDs tend to vary in intensity over time, so if a particular area requires consistent lighting, this could cause problems down the road. Since different manufacturers produce LEDs with different color temperatures and levels of brightness, it can be difficult to find LED lights that match each other perfectly without test-fitting them all first. Consider the following when selecting LED lights for any project.

1. Use quality LED lights: Invest in high-quality LED lights to ensure that it is consistent and reliable. 

2. Regularly monitor and replace bulbs: Over time, LED bulbs can become less bright, so regularly monitoring the hours they are on and replacing them as needed can help ensure consistency in output.

3. Inspect diffusers and fixture covers: Make sure that included or added diffuser materials on enclosed LED lights are UV-treated and will not cause dimming or yellowing over time.

4. Utilize dimmers: Utilizing dimmers when possible can help to regulate the output of the LED lights, allowing users to get the most out of them e.g. adjusting the brightness to match the current brightness of a set of LED lights where it is added.

5. Choose the right color temperature: Different types of LED lights are available with different color temperatures, so choosing the same color temperature is essential for achieving a consistent look.

6. Choose dimmable, CCT-Selectable, and watt-switchable LEDs: With modern dimmable, color-selectable, and watt-switchable lighting products available at Duralec, you can make adjustments to the energy intake, temperature, and light output with a single installation. Many of these lights are retrofit, and can be easily installed in existing standard fixtures.

CCT-Selectable LED Products

Switchable Wattage LED Products

Duralec's switchable wattage LEDs have the ability to be switched between two or more different wattages. This type of LED is used in a variety of applications, such as ambient lighting for residential and commercial spaces, and industrial lighting for warehouses and manufacturing facilities. Switchable wattage LEDs provide the user with the ability to adjust the intensity of the light output from their LED fixtures based on their current selected wattage input, offering significant energy savings in the process.

Choosing The Most Efficient And Elegant LED Fitting For Any Type Of Ceiling

It goes without saying that ceilings are not built the same for every structure, and so the light fixtures that can be installed on them would depend on the way it was designed and constructed. Taking time to learn about the fixtures that fit well into your existing ceilings or renovation plans can help prevent costly mistakes and make sure that you get the most efficient and elegant lighting for your budget.

When choosing LED light for ceilings, you will want to look for fixtures that provide a comfortable and even light distribution with the appropriate lumen output for the ceiling height and the room size. There are 3 main things to consider when choosing ceiling lights:

1. Ceiling Construction: The method of installation for the LED fitting will vary depending on the height and method of construction of the ceiling.

2. Task: Consider what intensity of lighting you need – task lighting, ambient lighting, or accent lighting should all be considered when selecting ceiling lights.

3. Style: The style of the ceiling lights should match the overall design of the space. Consider different materials, shapes, sizes, and colors to find something that fits the interior.

Main (Structural) Ceilings

Main (structural) ceilings are the most basic ceiling type that consists only of the concrete slab with no other materials added. This ceiling type is common in low-rise buildings and apartments.

The recommended LED light fittings for main (structural) concrete ceilings are the track, pendant, and flush-mounted.

Track lighting is a great choice for concrete ceilings as it offers adjustable, directional lighting that can be used to highlight specific areas of a room.

Duralec's LED refractor bulbs are a great option, providing light up to 5000K. They come in many common mogul base sizes including E26 and E39 and fits readily into track lighting fixtures.

Flush-mounted lights can also be used for both task lighting and ambiance. Flush-mounted lights are installed directly to the ceiling, giving them a recessed, streamlined look. Semi-flush lights are slightly recessed but still hang down from the ceiling with a short stem or cord. They provide a more direct illumination than flush-mounted lights and can be used in areas where there is limited space above the fixture.

Duralec's LED refractor bulbs are a great option, providing light up to 5000K. They come in many common mogul base sizes including E26 and E39 and fits readily into flush-mounted lighting fixtures.

Duralec's LED UFO High Bay Lights are a great option, set to 5000K with Daylight Harvesting Occupancy Sensor. They come with hooks for fast and easy pendant installation. 

Dropped Ceilings

A dropped ceiling, also known as a false ceiling or suspended ceiling, is a type of secondary ceiling that hangs below the main (structural) ceiling. The 2 most common types of dropped ceilings include the T-bar or grid type and flat drywall.

T-Bar or Grid Type Ceiling

The T-bar or grid-type ceiling has a visible grid system that holds removable tiles or panels made of drywall or acoustic boards with light panels and HVAC installed in between. They are the most common ceiling construction for commercial buildings such as offices, retail stores, studios, and schools. It allows for easy access to the wiring, lighting, HVAC, and plumbing while maintaining a modern and contemporary look.

The recommended LED light fittings for grid-type ceilings are panel lights and troffer lights.

Panel lights are a cost-effective and highly efficient lighting solution that can easily replace traditional fluorescent fixtures. They provide a soft and unobtrusive light and are flexible enough to easily change colors and intensity if desired. These lights are also easy to mount with minimal hardware, making them a great choice when looking to update existing drop ceiling fixtures to LED.

Duralec's LED Panel Lights are a great option, providing light adjustable between 3500/4000/5000K and can be dimmed from 0-10V. They come in many common grid sizes including 2x2, 1x4 and 2x4, and are easy to install.

Troffer lights offer a concentrated light source and attractive appearance, which makes them ideal for nearly any space including office buildings and homes.

Flat Drywall Ceiling

Flat drywall dropped ceilings are typically made of drywall boards for a smoother finish. This ceiling type is common in building hallways and lobbies, and residential homes, where plumbing and wiring are located in the space above the drywall and the main ceiling. This allows for easy access to the wiring, lighting HVAC, and plumbing while still maintaining a smooth, finished look.

The recommended LED light fittings for flat drywall ceilings are recessed downligts and strip lights.

Recessed round downlights provide a clean, modern look that complements the flat dropped ceiling while also occupying minimal space. Choose housed recessed lighting for ceilings that are rated for areas with higher clearance (6-inch to 8-inch drop). Choose slim or wafer-thin recessed lighting fixtures that are rated for areas with lower clearance (3-inch to 5-inch drop).

Duralec's LED Downlights are a great option, providing light adjustable between 2700K/3000K/3500K/4000K/5000K and can be dimmed from 0-10V. They come in many common recessed light sizes including 4-inch, 5-inch and 6-inch for residential applications and 8-inch for commercial applications, and are easy to install.

Recessed strip lights provide functional and decorative lighting. These lights are typically installed on thin grooves on the ceilings, where they can provide bright, even illumination with minimal distraction from other light sources. They are available in a variety of lengths and colors, allowing them to be tailored to fit any interior design scheme.

Duralec's LED Strip Lights are a great option, providing light adjustable between 3500K/4000K/5000K and can be dimmed from 0-10V. They come in 4-feet and 8-feet lengths, and can be installed in different ways - recessed, retrofit, surface, hanging or continuous row mount.

Interstitial Space Ceilings

Interstitial space ceilings have a gap between regular-use floors, specifically in buildings with clean rooms and laboratories, healthcare facilities, and food and drug preparation facilities. This type of ceiling is often used to house the inner mechanics of a building, such as plumbing, electrical wires, ductwork, special machinery, and lighting.

Maximize ROI with LEDs: See how much you can save by switching

LED lighting technology has revolutionized the way we light our homes and businesses. LEDs are now the most popular form of lighting, due to their long lifespan, energy efficiency, and cost savings. LED lights can help maximize your return on investment (ROI) by reducing operating costs and increasing efficiency. Read on to learn more about how much can save by switching to LED lighting.

By switching to LED lighting, you can save money in the short term through decreased energy consumption and in the long term through reduced maintenance costs. You may even qualify for additional incentives from utility companies or local governments for using LED lights. Additionally, you’ll be helping to reduce your carbon footprint by using an energy-efficient lighting option.

On average, an LED light bulb can last up to 25 times longer than a comparable traditional light bulb and uses 70%-90% less energy, so you can expect to save hundreds of dollars in energy costs over the lifetime of the bulb. 

The exact amount of money saved by switching from traditional lighting to LED lighting depends on the wattage of the lights being replaced, how many hours per day they are used, and the cost of electricity in your location. In summary, switching to LED lighting can save homes and businesses between 70%-90% on energy costs. 

How much do you save by switching from Halide to LED?

How much do you save by switching from CFL to LED?

LEDs consume around 75% less energy to produce the same amount of light as CFLs. The average lifespan of a CFL bulb is between 8,000 and 15,000 hours while LEDs can last up to 50,000 hours. This means you don’t need to replace the bulbs as often, saving you time and money in maintenance costs.

LEDs also produce a wider range of colors than CFLs and have dimming capabilities, making them more versatile for both indoor and outdoor settings. 

How much do you save by switching from fluorescent to LED?

LEDs consume around 80% less energy to produce the same amount of light as fluorescents. The average lifespan of a fluorescent bulb is between 8,000 and 15,000 hours while LEDs can last up to 50,000 hours. This means you don’t need to replace the bulbs as often, saving you time and money in maintenance costs.

LEDs also produce a wider range of colors than fluorescent and have dimming capabilities, making them more versatile for both indoor and outdoor settings.

Recessed lighting is a type of lighting installation where the light fixture is concealed within a hollowed-out area in the ceiling or wall. It creates a more subtle and elegant look than traditional overhead-mounted lighting fixtures and can be used to create dramatic lighting effect to any space. Recessed lighting can make a home or property more attractive to potential buyers. Statistically, it adds anywhere from 1% to 5% to the overall value of a property - enough to cover the entire realty agent fee for some.

Parts: Housing, Trim and Bulb

Recessed lighting consists of three main parts; the housing, trim, and bulb.

• The housing is the part that gets installed into the ceiling or wall cavity and provides the base for the bulb and all other components usually made with fire rated materials and insulated. The housing is installed separately or built in on some new, modern LED fixtures.
• The trim is the material that surrounds the housing, holds up the bezel and the cover, and fastens them on the ceiling or wall. The trim is installed separately or built in on some new, modern LED fixtures.
• Finally, you have the bulb as a light source, with LED as the most popular and suitable option.

Many LED lights for recessed lighting available at Duralec from manufacturers like Intrinsix, Luxurio, Topaz, Cree Lighting, Maxlite, Eiko and Keystone were engineered to retrofit existing recessed housings and bulbs and can be easily installed without major remodeling or rewiring.

Choosing the right LED recessed light

Recessed lighting is ideal for providing a soft, subtle light that doesn't take up too much ceiling space. Recessed lights provide even illumination and can be used to highlight certain areas, such as artwork or furniture. If you have low ceilings, recessed lights can help raise the ceiling height and make the room appear higher and wider. If you want to create an intimate atmosphere in a room, recessed lighting is ideal because it gives off a more diffused light than traditional lights.

Adding recessed LED lights with housing

If you’re building a new home or remodeling, you can typically expect to pay additional for each housing fixture for recessed light installation as it requires cutting into walls and ceilings, running electrical wires, and patching up the wall or ceiling afterward. 

Choosing a recessed light housing

Recessed light housings are usually IC-rated and airtight because they are designed to be installed in direct contact with insulation. The IC rating indicates that the recessed light housing has been tested and approved for use in insulated ceiling applications. An airtight design prevents heated air from entering the enclosure, helping to keep temperatures low and reducing the risk of fire.

Power Source: Line Voltage vs Low Voltage

Recessed Lighting has a few key differences that should be taken into consideration when deciding which type of lighting to install.

• Line voltage recessed lighting is typically powered directly from your main power supply and can be used to light large rooms or entire floors of a building.
• Low voltage recessed lighting uses a transformer to reduce the line voltage and steps it down to 12 volts or 24 volts. This makes it ideal for smaller, more enclosed spaces such as closets, or bathrooms where there may not be enough space for bulky fixtures. Additionally, since the reduced voltage reduces the chances of electrical fires, it is a safer option than line voltage lighting. Low voltage recessed lighting is also more energy efficient and can last up to twice as long as line voltage varieties.
