Looking to convert your high bay fixtures over to LED? Here are 7 reasons why you should consider switching to efficient LED high bays. 


Reducing commercial high bay lighting costs becomes practical and sustainable with our energy efficient indoor high bay lights. With energy savings up to 75%, you can reduce a tremendous amount of energy consumption.  Also save with LED high bays via longer lifespans, reduced maintenance costs, motion sensors, dimmable high bay lighting options, and even rebates. 

Savings with LED


Our efficient LED high bay lights are L70 rated last upwards of 100,000+ hours. This allows for less replacements of your bay fixtures, which is costly in applications such as a factory or warehouse where high bay lights are used due to the extreme heights they are installed at. This cost saver of LED high bay light fixtures is often overlooked, but saves a tremendous amount of money.


Our industrial high bay LED light fixtures are able to withstand extreme cold and hot temperatures (all the way up to 190F), without decreasing its lifespan. This is possible through our large heat sinks, specially designed to keep the lights cool. Our quality LED high bay fixtures are also vibration resistant, allowing them to maintain a long lifespan in harsher environments, perfect for commercial & industrial environments requiring industrial high bay LED lighting fixtures.


Are you trying to replace high bay fixtures that are 277V? 347V? 480V? We have solutions that cover these higher voltage installations. Our constant current drivers are equipped to handle everything from 100V to 277V or 377V to 480V (standard driver in our kits are 100V-277V). We can handle single or 3-phase power as well. Talk to our sales engineers and we can get your lighting situation taken care of.



Tired of changing tubes? Tired of tubes that don't last as long as they should? Replacing T5 HO Fluorescent fixtures is simple and easy. Each T5 tube produces approximately 4000 lumens each. The light is not directional, so effective lumens is actually less than the 24000 combined lumens for a 6 tube fixture. We can easily replace these fixtures with a cost effective, maintenance free equivalent LED solution.

Have a hot environment? We have LED High Bay Lights that are rated for ambient temperatures for 60C, 70C, 80C and even 90C. These lights are engineered to last, and many of them can be configured to be either installed as a high bay or a flood light.


Many of our commercial LED high bay fixtures are designed with an IP rating. IP (Ingress Protection) is a rating system that determines how well a fixture can keep out dust and moisture. It is represented as IPXX, where the first digit is how well it keeps out dust and the second digit talks about how well it keeps out water.

We have a line of Commercial High Bay fixtures & products that are rated IP65, IP66 and IP67. How much do you need? Typically IP65 LED high bay is all that is required unless you have an environment where strong pressurized water is being directly sprayed on to the bay fixtures. They can even be used outdoors.

Types of High Bay Fixtures


When selecting light fixtures for high bay applications, the most important thing is efficiency. Since the light fixtures will light up the space from a high point, the light must be optimized for illumination. UFO high bays have a very unique design that plays a crucial role in their efficiency. Their massive UFO style heat sink ensures they transfer thermal properties more evenly and efficiently. Models are available to replace 250W, 400W and 1000W HID. We have models that returns close to 100, 000 lumens of powerful, directed LED Light to the work surface below.

UFO LED high bay lights provide light that is powerful and uniform. They are very well constructed and have IP65 rating, meaning they can be installed in harsh environments and still work well. UFO LED lights are also either UL or ETL Listed for safety purposes and DLC qualified, which means you may be able to get a rebate from your utility company.

One thing UFO LED Bay light fixtures do well is merge functionality with style. When installed in a space, they enhance its style because of their striking appearance. These light fixtures are ideal for high bay applications that need beautiful, functional light. 


Panel style LED high bays have a look that is similar to that of troffer style panels; they look like T8 and T5 fluorescent fixtures. Models are available to replace 250W to 1000W Metal Halide.

Their major benefit is that they have the ability to distribute light over a large area, so you may need fewer light fixtures to sufficiently illuminate your space. These fixtures also have large heat sinks which excellently dissipate the heat their LEDs produce.

Since panel-style LED high bays resemble T8 and T5 fluorescent lamps, they make perfect replacements for these lamps. They can also be used in place of linear fluorescent lamps. Panel-style LED high bays can replace these traditional lamps and lower energy consumption while providing sufficient light. 


These high bay fixtures are normally used in grocery stores, warehouses, and wholesale club stores. They have beam angles which are perfect for use between aisles. If your high bay application has many aisles, these are the light fixtures you should get for the space as their optics are designed to perfectly light up aisles.

Linear LED high bays are DLC Qualified and are either UL or ETL Listed, so the initial costs of buying them will be reduced by the rebate you get from your utility company. Linear aisle high bays combine the awesome power of LED with functional design to provide a lighting solution that is both powerful and practical. 


For those who want to switch to LED technology and also save money, this is the best option. A retrofit kit is usually installed in the existing traditional light fixture and the conventional bulb and ballast are replaced with a LED head and driver. Retrofit units can be more affordable than new LED high bay light fixtures because they are cheaper to manufacture – they have fewer components. They are also cheaper to install as their installation process is not complicated. 


Better Lumen Intensity

The modernization of today's light source has created a considerable improvement in energy efficiency. Thanks to the innovative technologies in the lighting industry, such as the use of LED, and controls that work with these lights, lighting products are now more efficient and energy consumption has gone down substantially. This translates into a large reduction in the cost of lighting.

Allow us to take a little time to explain in detail how LEDs have better lumen intensity than HID lamps (which are used in some high bay lighting applications).

1. LED High Bay: Initial Lumens

The truth of the matter is that all light sources fade over time, no matter the technology. What happens is that light intensity diminishes to the extent it becomes inefficient. This does not mean the light has failed, it just means that the usefulness of the light has diminished significantly. When a lighting fixture is installed in an application and it is switched on, its luminosity is highest at that point. This is called initial lumens. The initial lumens for LED lights are usually measured 45 minutes after the lights are switched on as the LED diodes need time to stabilize. When it comes to HID light bulb, the initial lumens are calculated after 1,000 hours of initial use.

2. LED High Bay: Lumen Maintenance and L50, L70 and L90 Rating

Lumen maintenance is related to the lifespan of a light source. LED lights do not burn out like traditional lighting systems. Rather, they continue working as long as there is an electrical current . What happens is that the light intensity fades gradually, rendering the luminaires obsolete and inefficient.

For LED lighting products L50, L70, and L90 are used to calculate the lifespan of a LED diodes circuit board in hourly increments. Lighting experts use these ratings to estimate the amount of light the LED diodes produce when the luminaires diffuse 50% (L50), 70% (L70) or 90% (L90) of the quantity of initial lumens. The L70 rating is the most popular and is used to indicate the point at which LED lighting products will lose 30% of their lumen intensity (and maintain 70%). So when you look at the specifications of a LED product, the total life of the product may vary from the L70 lifetime established for the LED themselves. Other components may fail before the LED's hit their L70 life. However, these components, in well designed LED products, can be replaced (easily).

A 70% deterioration in light output corresponds with the point at which the human eye notices a decline in the intensity of light. However, the human eye is only negatively affected when the light intensity of a light source reaches a level of 30%.

So, when a luminaire manufacturer states that a luminaire has a 50,000 hour lumen maintenance, it usually means that we will only notice a decrease in light intensity after the light source has been in use for 50,000 hours. But you should not take this to mean that the luminaire will stop functioning.

L70 Rating
3. LED High Bays: Delivered Lumens

The term delivered lumens (absolute lumens) usually describes the luminous flux produced by a light source when its optical loss factor is taken into account. When it comes to traditional HID High Bay lighting technology, only the light intensity of the lamps is measured, the optical loss is not included in the calculation. Including delivered lumens is very important, because HID lamps do not deliver the same amount of lumens they produce. This is key when you compare specification of a HID High Bay and a LED High Bay, because what you think you get with a HID High Bay is not what appears to be advertised.

But when it comes to LEDs, the story is different. When LED luminaires are being tested, the optical loss factor is usually taken into account. So, in the case of LEDs, we actually refer to the delivered lumens when we talk about their light intensity.

When comparing the light output of a HID lamp with that of a LED lamp, a variety of factors must be examined. These include the lifespan of the light sources, the optical loss factor (particularly for high intensity discharge light sources), and the lumen maintenance over time.

In a nutshell, when the luminous flux of HID lamps and LED lamps used in High Bays and other fixtures are compared, LEDs are observed to have much better light intensity. Measuring the luminous flux of a light source helps us to know its efficiency. This way, we can choose the one with a higher number of delivered lumens – which is always LED. 


Luminous Efficacy (Lumens Per Watt)

Lumens Per Watt

Luminous efficacy is the true measure of a bulb’s efficiency. It indicates the lumens produced for every watt of electricity consumed. LED bulbs are more efficient than traditional bulbs as they have a higher luminous efficacy. High quality LEDs have awesome efficacy ratings; the standard luminous efficacy is currently 100 lumens per watt. This means that a good LED bulb should produce 100 lumens for every watt of energy it draws.

Think of luminous efficacy as bang for the buck. The efficiency of your new LED high bay lights will be seen in the reduction of your electric bill as utilities charge by the watt. If you get LED high bays with a high luminous efficacy, they will pay for themselves very quickly.

Color Temperature

Color temperature, which is also known as correlated color temperature, accurately measures the temperature of a light source. The Kelvin scale is used to measure a bulb's color temperature because of its accuracy in measuring very hot and cold objects. Bulbs with a low color temperature produce warm light (in the red, orange, and yellow spectrum's) while those with a high color temperature produce cool light (in blue and white spectrum's).

HID and fluorescent lamps generate light in different colors, however, the color range is limited. On the contrary, LEDs produce light in a wide range of colors. The standard color temperature for industrial and commercial spaces is between 4000K and 5500K. Spaces that need very bright light – like show rooms, parking lots, and assembly lines – need lights with a color temperature of 5000K. Most bulbs used in offices have a color temperature of 4000K as very bright light isn't required in these spaces. 

Kelvin Color Temperature

Color Rendering Index

Color rendering index defines the color of light and tells us how well a light source will reveal the colors of items compared to sunlight (the ideal light source). When it comes to high intensity discharge lamps, people usually complain about one thing: poor light color. Light color is extremely important in low bay applications because it has a huge impact on clarity and contrast.

Most high bay applications require a high level of illumination for work to be done well and productivity to increase. Powerful lighting helps maintain the proper foot candle levels for adequate illumination. If these levels are not maintained, accidents may occur.

The Beam Angle

LED Beam Angles

The beam angle is what determines how light will be distributed. A wide beam angle produces general, softer light and distributes the light better to different areas of a room. A narrow beam angle produces concentrated light which is good for accent lighting, it makes the light more intense and focused. LED lights are available in a range of beam angles: from 15° (narrow) to 120° (wide). Choosing the right beam angles can greatly improve the lighting in a high bay application. With LED, you won't need a reflector to gather the light and direct it to the ground, like you would when using a Metal Halide High Bay fixture.

LED Optics

The Warranty

A good quality indicator of LED high bay lights is their warranty. Reputable LED manufacturers always honor their warranties, provided they are valid. When checking the warranty, be sure to check the warranty for the LED head and the driver as they may be listed separately. High-quality LED high bay lights usually have a 5 to 10 year warranty. Most manufacturers give a 5 year warranty for the LED drivers – which is the industry standard.

Do not be tempted to buy low quality LED high bays as they may soon malfunction, forcing you to spend money on new light fixtures. Your business activities will also be disrupted by poor lighting or light replacement. 

LED Warranty


1. Run a photometric to determine proper light levels.

Determine how many lumens the LED high bay fixture will produce before ever having to commit to purchasing or sampling.

Here is the information we need to run a photometric study
  • dimensions of building - height, width, length of room
  • mounting height
  • reflectivity of building (walls, ceilings, floors)
  • any tall structures like machines or shelving  that might obstruct light distribution

Once we are done, you will have the results and confidence that our selection will work in your building.

3. Determine if Controls Make Sense.

We can give you options on dimming, motion sensors and bi-level light levels. This is important for buildings that need better efficiency to take advantage of even more cost savings. 

LED Controls


Everyone wants a good deal. But when you compare two high bays, both with the same watts, based on price, there's more that you need to understand before you purchase.

1. What are the total lumens for the watts you are buying?
Don't expect them to be the same. Efficiencies vary greatly between LED Products. A 150W High Bay can produce less lumens than a 120W High Bay. You may be buying 5 year old technology. That is why this is a cheap high bay. The goal is to produce the correct amount of lumens using the least amount of power. Always compare the lumens of the light, and the amount of watts it takes to generate those lumens. 

2. What components are installed in these units?
LED Diodes and Drivers are important. Are they using brand name diodes like CREE or Nichia? Are they using safe reliable drivers like Meanwell or Inventronics? Or have they substituted something that is private labeled or branded to their company name? That is one of the oldest games in the LED world - cheapening the solution to lower the price. The old saying may still apply - Buy Cheap - Buy Twice. 

3. How good is the warranty?
Who services the warranty? How long is the warranty? A good indication of how long the manufacturer thinks a product will last is the length and language of their warranty. Check their ratings with BBB. Google the companies name. You'd be surprised how many times a bad company will appear in search engine results. Do the research before you buy. It will save you more money in the long run. Many companies offering cheap products are no longer in business. Who will service your warranty once they close the doors forever?

4. High Bays that are built cheaply units may be hard to maintain
They are typically designed to be thrown away when they fail. A higher quality high bay has been engineered to be able to replace parts, like drivers and sensors. Would you throw away your car because you have a flat tire? Of course not.
