How to Choose the Best LED High Bay Light

Choosing the right light for a space can be confusing, but picking the right high bay light brings with it extra pressure. High bay lights are used in spaces like warehouses and factories, where visibility is critically important. It’s important to get it right.

Fortunately, there are many exceptional LED high bay lights on the market. Choosing the right one is a matter of matching your particular application—warehouse, factory floor, gym, retail space, etc.—with the correct power and features of the best lights available. Let’s review the major factors to consider with this type of fixture.

What Makes a Good High Bay Light?

The current boom in warehouse construction makes this discussion of high bay lights more relevant than ever. Warehouse lighting is a classic use case for high bay lights. These lights guarantee great visibility for work and safety. Here are some issues to consider.

Performance: Because performance is critical for high bay lights, LED options are by far the best choice. LED fixtures provide powerful lighting in a variety of lumen outputs (i.e., brightness) and color temperatures. LED lights are also highly reliable and have longer lifespans than competing products.

A good LED high bay light floods a space with powerful light no matter how high you hang the fixture. A light like the IntrinsiX CIRCA Round High Bay Light can produce up to 43,000 lumens. The CIRCA light produces bright, white light (up to 5,000K) that is perfect for situations that require the best visibility.

Whether your space is a factory floor, an aircraft hanger, or a school gym, an LED high bay light is the only fixture that delivers the performance required.

Safety: High bay lights are a key element to a safe workplace where visibility is important. Workers in spaces like warehouses, workshops, or factory floors often have to deal with dangerous machinery. A well-lit facility is crucial for protecting workers from accidents. Proper lighting in workplaces is also legally required by federal and possibly state regulations. For example, the Occupational Safety and Health Administration (OSHA) requires a certain lighting standard be met for various parts of a workplace, from machine shops to stairwells.

Energy savings: LED high bay lights are also the best choice for the application because of their promise of immense energy savings. LED lights use up to 75% less energy than older technologies, and that means far lower electricity bills. The savings begin to accrue immediately, making the return on investment (ROI) for LED lights extremely high.

Further savings are gained on maintenance, due to the long lifespan of LED lights. The need to buy replacement bulbs and have personnel to install them plummets with LED lights.

Network ability: LED high bay lights are highly efficient and deliver major savings, but there is yet another level of savings available: the optional use of advanced lighting controls (ALC). Also called networked lighting controls or smart light controls, this technology allows you to tie your lights into a programmable network that turns them on only when necessary. This combination of software and hardware is the next generation of energy savings. For example, you could program the lights to turn on and off according to even the most complicated schedule. A further possible step would be to make the lights more automated by employing sensors on the lights to adjust to daylight or worker occupancy.

The ability to affordably and easily program your lighting grid is the next frontier of building maintenance.


Options for High Bay Lights on the Market
—UFO Lights vs. Linear Lights

When looking for LED high bay lights, it’s smart to go with a reputable distributor. This guarantees that you get a certified, high-quality light with proven success and a great warranty. Here are some ways to narrow your search.

Shape and configuration: It’s not often the term UFO makes its way into a commercial lexicon, but here we are. One of the main shapes of high bay lights is the UFO light—a round, saucer-shaped light that is suspended from the ceiling. Sometimes called a round light, the UFO light is a favorite of lighting designers for high-ceilinged spaces like warehouses or factories. They cast their light powerfully and evenly across a space and are perfect for putting into an array. The IntrinsiX CIRCA light mentioned above is a UFO light. Besides being highly practical, this UFO LED light has a modern, industrial look that makes a space look great.

The second most common shape for high bay lights is a linear light. This fixture is rectangular in shape, and its LED lights are arranged in a line

(hence the word linear). These lights loosely resemble flat panel LED lights, and, like flat panels, they can be mounted either flush or suspended. Linear lights offer powerful lighting with easy installation. Top products, like the Altitude Linear High Bay LED Light, provided by Duralec, offer high-quality drivers, many mounting options, and integrated sensors.

Wattage: Like most LED lights, high bay lights come in a variety of wattages. These wattages correlate to how bright the lights are. Not all lights are created equal, however. The best fixtures, like the IntrinsiX CIRCA UFO light, are DLC Premium rated, meaning they deliver 130 or more lumens per watt.

The CIRCA light comes in five wattage options (100W, 150W, 200W, 240W, and 300W) and has selectable wattages on all but the most powerful model. This means you can tailor your light to your specific needs. As always, your application is the key factor in determining which light you need.

Mounting options: High bay lights are mounted in a variety of ways due to the high ceilings involved. Good LED high bay lights offer a variety of mounts that will work in whatever application you have. For example, the IntrinsiX’s CIRCA UFO LED light comes with hardware for either pendant or surface mounting. IntrinsiX’s Altitude LED linear light comes with V-shaped hangers and strong chains for hanging the fixture, as well as surface-mounting options.

Emergency backup: LED high bay lights provided by Duralec have optional emergency backup units, as well. These battery packs ensure that your facility never goes dark. This is crucial for worker safety, as well as for legal compliance in many areas (especially egress areas).

Sensor options: The best LED lights today come with a variety of sensors. This technology is what turns a good LED light into something great. Sensors allow lights to be controlled in ways that lead to much better lighting as well as to huge energy savings.

The most common sensors include the daylight harvesting sensor. This photocell device senses how much ambient light is available—say, coming through windows or skylights—and, with the proper controls, can tell a light to adjust to it. Another top sensor is the occupancy (motion) sensor, which can sense when a person enters or leaves a room. The potential of these sensors to save money is immense.

These are just some of the options available for LED high bay lights. To talk about your specific needs, feel free to reach out to a Duralec expert today.

The Hidden Benefits of a Spec Sheet (or How to Read a Spec Sheet)

Today’s product spec sheets for LED lighting fixtures are so packed with information that they can sometimes be confusing. A good spec sheet contains technical details that fully describe the product, but some of those details can sound like jargon. This article is an explainer of those terms, standards, and features. As a point of reference, let’s use this spec sheet for the IntrinsiX CIRCA Round High Bay LED Light.

Wattage: Perhaps the most important number on a lighting spec sheet is the wattage of the light. This number refers to the power a light needs to run at its maximum level. On this spec sheet, this number appears on the front page and is also the first bullet point listed on page one. This high bay light is offered in wattages of 100, 150, 200, 240, and 300 watts.

The higher the wattage of a light, the brighter it will be (although brightness is measured by its own metric, which we will get to soon). LED lights require far less power than previous technologies (like high-pressure sodium or metal halide lights). Their wattage numbers, therefore, are relatively modest. The powerful light seen in this spec sheet—suitable for warehouses, factories, and the like—comes in wattages between 100W and 300W. To give you an idea of how much more efficient LED lights are: not long ago, you might have used a 100W light bulb for a table lamp at home.

Today, a 100W LED high bay light can flood a warehouse space with powerful white light; the 300W version is obviously even brighter.

Your application determines which wattage you need. A warehouse high bay light likely needs a higher wattage than a similar light in a workshop, simply because you need more light in a warehouse. This is why the wattage rating for a product plays such a big role in its spec sheet—it is the best way to categorize the products. In the bottom half of the spec sheet, the wattage of the lights is the key factor in separating the products.

Lumens: Lumens is the best measurement for brightness. Lumens (Lm) being the form of measurement. This number tells you how much light the bulb or fixture will produce. Brightness correlates roughly to wattage within a product type; in other words, a 300W light will produce roughly three times the lumens of a 100W light.

You will often see a lumens-to-watts (lm/W) rating on a spec sheet, and if you do not, simply divide the total lumens by the total watts! However, different product types on the market—say, LED lights versus fluorescent lights—have different lumens-to-watts ratios; that fact demonstrates how much more efficient LED lights are than older technologies. Lumens per Watt is quickly becoming the go to way to choosing the most efficient and correct light as you want the highest efficacy.

The Specifications portion of this CIRCA spec sheet indicates the lumen output for the five varieties of this high bay light. The first four wattage sizes (100, 150, 200, and 240W) show three different lumen outputs because those lights have variable settlings; for example, the 100W light can operate at 60, 80, or 100W. Therefore, that light also has three different lumen outputs available.

Color: The “color” of a light, also called its color corrected temperature (CCT), is measured in degrees Kelvin (K). The light’s color refers to how warm or cool a light appears. A cozy library wants a soft warm light, whereas a warehouse wants a clear, white light. A conference room or office wants something in between (a cool color for good visibility).

In a spec sheet, look for “color selection” or “Kelvin Temp variables” or “CCT.” Sometimes a light will have three or more selectable color temperatures. The IntrinsiX CIRCA high bay light in this spec sheet has narrower applications—warehouses, supermarkets, and so on—than other general-purpose lights, so it only has two color temperature options (4000K/5000K, seen on page 3).

Color Rendering Index: This measurement, also known as CRI, reflects the quality of light and its ability to show you the most natural colors (of objects) possible. By the definitions of CRI, the best color-rendering light is that produced by a natural light source like the sun.

CRI is rated on a scale of 1 to 100. At the low end of the scale, colors look distorted or unnatural. At 100 CRI you are seeing the “true” colors of an object. Today’s LED lights produce much higher CRI light than many previous technologies, including fluorescent lights. Lights with ratings over 80 produce excellent light that makes everything it touches look natural.

Voltage: The input voltage can range from anywhere between 120-480. This is reflected on most spec sheets. (The “V” stands for volts, and the “VAC” stands for volts of alternative current. They are more or less interchangeable.) Most wiring in a building is 120-277V, where buildings that have more powerful equipment can range all the way up to 480V. Common high bay lights like the LED IntrinsiX CIRCA usually run on 120-277V. However, larger fixtures can use 277V-480V circuits.

DLC Rating: Spec sheets of high-quality LED lights will likely mention a DLC rating. The DLC is the Design Lights Consortium, a non-profit organization that creates standards for lighting performance and gives products a rating. Their goal is to guide the lighting industry toward high-quality, efficient, and long-lasting products.

The best DLC rating at the moment is DLC Premium.

The best DLC rating at the moment is DLC Premium. Any light with this rating—including the one in this CIRCA spec sheet—is certified as having high levels of performance in many areas, including its resistance to long-term dimming. Look for the DLC Premium certification as a logo on your spec sheet (seen on page 2 of this sheet) or in a mention of it in the text.

UL Rating: There are a couple ratings for safety in electronic components, and it can be a little difficult to tell them apart. At the very least, your light fixture should have one of these ratings. The UL rating is granted by the testing laboratory called Underwriter Laboratories (UL). This laboratory tests products against the standards set by the International Electrotechnical Commission (IEC). Underwriting Laboratories is also a part of the Occupational Safety and Health Administration’s (OSHA) product testing program.

When a product wins a UL rating it is certified as having met the strict safety standards of the organization. Look for a “UL” logo on a spec sheet or some mention of it in the text. A UL rating also comes with quarterly “surveillance” of the product. This ensures ongoing product quality, performance, and safety.

ETL Rating: This rating is closely related to the UL rating and is another good indication of product safety. The ETL rating is granted by the Electrical Testing Laboratories. This lab, like the previous lab, is also part of OSHA’s testing regime. It simply uses slightly different criteria for judging the products it tests.

IP Rating: The IP rating is sometimes called the “waterproof rating.” IP stands for “ingress protection” and addresses how safe a product is from dust, moisture, and other harmful materials (or bugs) getting into a lamp or fixture. This standard was also developed by the aforementioned IEC.

Most IP ratings of light fixtures are either IP65 or IP66. An IP65 rating guarantees protection against dust, moisture, and even sprayed water. A light with this rating is very resilient against the elements. The IP66 rating, however, is even strong—it indicates protection against dust, moisture, and heavy sprays or blasts of water. (IP67 and IP68 score protection against varying levels of water immersion.)

This high bay light spec sheet lists the IP rating under “Materials” on page 3. However, an IP rating could appear nearly anywhere on a spec sheet.

Warranty: A spec sheet for a high-quality LED light or fixture will mention a warranty. One of the best qualities of a modern LED light (for both users and the environment) is its long lifespan. Manufacturers generally offer extremely long warranties on these products.

In the case of this spec sheet, the IntrinsiX CIRCA high bay light has a manufacturer’s 5-year, 50,000-hour warranty (seen at the bottom of page 3).

Duralec oversees all warranties for this and all of its best-in-class products.

Photometrics: The graphs you see on a good spec sheet are called photometrics. These graphs represent how a light performs and disperses across a distance. One such graph of this dispersion is sometimes called the light’s luminous intensity distribution. This graph shows not only the width of spread but also how many lumens are projected at different distances. The same graph might also include the average diffuser angle, which shows how widely the light spreads. Another graph might show the light’s average effective illuminance, which includes the light’s beam angle.

These photometrics attempt to show you what you get with a certain light. They can be very useful when creating a lighting design and allocating lights across a space.

How to Choose the Best Transformer

Transformers have been around for almost two hundred years. The technology began with the discovery of electromagnetic induction by the English scientist Michael Faraday in the 1830s. (Other scientists probably discovered it around the same time, as well.) Induction is the phenomenon in which a changing magnetic field (magnetic flux) creates a current in a nearby wire. An electrical transformer uses this phenomenon to convert one voltage to another. Since the 1800s, inventors have been making better and better transformers. Today, transformers are crucial components of our electronics as well as our electrical grids.

When choosing a transformer, the top concern is picking the right one for your application. Small transformers come in a variety of sizes and configurations and are suited for electronics or other devices. Large transformers, on the other hand, are capable of connecting you (your building, your campus, etc.) to the power grid. Let’s review some of the considerations when choosing a transformer.

What Is the Right Transformer for the Job?

No matter the size of the transformer, a few factors are key in determining which the best fit is. Understanding these factors—and weighing which are the most important to your project—will ensure long-term success, safety, and savings.

 

Protection from the elements: Transformers that require enclosures offer many options that meet NEMA (National Electrical Manufacturers Association) standards. Many transformers come with NEMA 3R rated enclosures, along with weather shields. (NEMA 4 enclosures are often available, too, and offer even higher levels of protection against elements like dust and moisture.) Because large transformers often sit outside, these high standards for protection are critical.

Transformers also offer a variety of cooling options to ensure optimal performance and long lifespans. Units are often ventilated or even outfitted with forced-air cooling. Oil or water cooling are also available. Transformers that are used indoors often have cooling systems filled with non-flammable dielectric fluids rather than oil, as an extra safety measure.

An example of these safety measures is seen on the Jefferson Electric Three-Phase Ventilated transformer (rated from 15 to 2,500 KVA). It has insulation rated to 220°C and a temperature rise of 150°C. This transformer is a good fit for all general loads, including lighting, industrial, and commercial uses.

Flexibility: Manufacturers such as Jefferson Electric or Hammond Manufacturing offer electrical transformers in a wide array of sizes and capabilities. Whether it’s a small transformer to fix a guitar amp or a 3-ton, 1000 kVA transformer to power your building, there are many options available and affordable on the market. The top factor for choosing a transformer is likely the voltage rating. The Jefferson Electric Three-Phase Ventilated transformer mentioned above comes in no fewer than 27 voltage options, from 15 to 2,500 KVA.

A huge variety of enclosures is possible, too. Housing dimensions for these large transformers vary from the size of a suitcase to that of a small car. These units can be mounted in a number of ways. Wall brackets are an option for transformers up to 75 kVA. Beyond that, transformers become very heavy, and a floor or concrete pad mount is likely necessary. Drip pans, pole-mounting brackets, and other hardware are also available.

Applications involving facilities with critical needs, such as hospitals or data centers, might require special transformers. Units such as drive isolation transformers or harmonic-mitigating transformers are appropriate for these situations. These units guarantee steady electrical supply in all circumstances. Other specialized transformers are suited for non-linear loads that occur in some buildings, such as offices that use large amounts of modern office equipment.

Efficiency: Today’s transformers are much more efficient than their early ancestors. Manufacturers have had decades to fine tune their designs, and many transformers today are nearly 99% efficient.

Small energy losses can occur in a couple of ways inside a transformer. Energy can be lost in the windings—the coils of metal wire—as well as in the transformer’s metal cores. Sometimes the energy is lost to resistance in the metal, resulting in unwanted heat. Other times, parts of the magnetic field are not fully converted into energy. However, advanced designs have rendered these losses minimal. Different designs include core, shell, concentric, and sandwich configurations of the windings and cores.

In short, the higher the quality of the metals, the more efficient the transformer will be. High-quality windings—either aluminum or copper, usually—and the best steel cores ensure minimal losses.

Seismic protection:Sometimes a transformer needs to be “seismic qualified” for a specific project or region. Critical facilities like hospitals, government facilities, or fire or police stations often fall into this category. In these situations, transformers must be guaranteed to work after seismic events like earthquakes.

Fortunately, many transformers have been built to this high standard and have undergone independent, third-party testing to gain the seismic qualification (the ICC-ES AC156 qualification). These units meet the International Building Code (2015 IBC), as well as the California Building Code (2016 CBC). Units can still be either floor-mounted or wall-mounted.

These seismic qualified transformers can be found in a wide variety of sizes and voltage ratings. For example, Jefferson Electric offers both wall-mounted and floor-mounted transformers in either single or three-phase encapsulated or ventilated models. These seismic qualified units guarantee legal compliance in applications or regions that require it. The seismic protection also offers an additional layer of protection even when not legally mandated.

Quality: Looking for high quality in a transformer ensures that you get a unit which performs at the highest level, runs efficiently, and lasts as long as possible. Duralec-provided transformers, for example, are best in class and offer top performance. High-quality metals in the windings and cores promise efficiency and minimal load losses. Good venting and cooling tools keep transformers running smoothly and add to their long lifespans.

A high-quality transformer will operate more quietly, as well. Some transformers produce a steady humming sound. This is the result of components expanding and contracting with the magnetic field. A transformer with higher-quality materials, however, will be quieter. Its better build quality will also lead to less long-term vibration and noise.

What Is the Best Linear Architectural Lighting Today?

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.
