Why choose MyLEDLightingGuide High Bays?

1. Efficacy (Lumens Per Watt)

130 lm/w
150 lm/w
180 lm/w

Luminous efficacy is the true measure of a bulb’s efficiency. It indicates the lumens produced for every watt of electricity consumed. LEDs are more efficient than traditional bulbs with a higher luminous efficacy. High quality LEDs have awesome efficacy ratings. The standard luminous efficacy is upwards of 130 lumens per watt

We have fixtures that are rated between 130 and 180 lumens/watt. We can help you choose the right efficiency.

MyLEDLightingGuide Pro Tip

Trade off between initial cost and long term savings?

A higher efficiency LED product costs more than lower efficiency units. The savings over the life of the product is more than the initial investment needed to upgrade. So if you're looking to maximize savings when converting to LED, choose the higher efficiency product.

2. Wet Location High Bays


IP rating designates a fixtures ability to keep out both dust and water. The first digit of the IP score designates dust protection, the second designates water protection. A water protection score of 5 or above helps protect your fixtures from water intrusion.

MyLEDLightingGuide offers IP ratings of IPx5, IPx6 and IPx7. This allows you to install these fixtures outdoors, exposed to the elements, if required.


MyLEDLightingGuide Pro Tip

What IP Rating do you need?

IP65 is all you will need for most applications. Extreme environments such as high pressure washes might need IP67 or higher.

3. High Voltage up to 480V



100V - 277V
277V - 480V

Are you trying to replace fixtures that are higher voltages, 277V to 480V? We have solutions that cover these higher voltage installations. Our constant current drivers are equipped to handle everything from 100 Volts up to to 480 Volts (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.

MyLEDLightingGuide Pro Tip

480V High Voltage Options

Our higher voltage solutions handle both single phase and 3 phase 480V installations. If you have voltage above 277V, tell our sales engineers so we can specify the proper driver.

4. Color Temperature Options



Color temperature or correlated color temperature, measures the temperature of a light source. The Kelvin scale measures a bulb's color temperature. Bulbs with a low color temperature produce warm light (in the red, orange, and yellow spectrum). Those with a high color temperature produce cool light (in blue and white spectrum).

We offer both 4000K and 5000K fixtures for indoor lighting. Not sure which one you should select? We can help!

MyLEDLightingGuide Pro Tip

LED Color Choice

To replace Metal Halide, 5000K is a great color choice. If you would like a warmer light, choose 4000K. HPS high bays are around 2300K. Moving to 4000K or 5000K will greatly improve the quality of indoor light.

5. Light Quality: Color Rendering Index

70 CRI
80 CRI
90 CRI


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

Most of our High Bay fixtures are offered between CRI 70 and 85. We can special order almost any CRI you might need. 

MyLEDLightingGuide Pro Tip


Anything over 70 is good. In applications such as assembly work where fine detail is necessary, then select 80 to 90 CRI.

6. Beam Angles: Proper Light Distribution



The beam angle is what determines the distribution of light. A wide beam angle produces softer light and distributes it better to different areas of a room.

A narrow beam angle produces concentrated light good for accent lighting. It makes the light more intense and focused.

Our LED bay lights are available in a range of beam angles: from 15° (narrow) to 120° (wide).

MyLEDLightingGuide Pro Tip

Beam Angle Selection

Ask us to run a lighting photometric to determine the perfect light and beam angle for your indoor space. Look at both the foot candle measurements and max/min ratios to make sure your space is bright and uniform.

7. Lighting Controls


Motion Sensors
Daylight Harvesters
Smart Controls

Motion Sensors and other controls can dramatically reduce lighting costs by turning off or dimming the lights when people leave the area.

PIR and microwave motion sensors can be added to turn the lights on when motion is detected and off / dimmed when no activity is detected. To dim, the bay fixtures need a 0-10V dimmable driver. Unlike traditional lighting, dimming LED fixtures is relatively simple and does not affect the life of the bay fixture.

And if you're trying to save additional money, nothing saves more money than off or 10% lit.

8. Speciality High Bays


High Temperature
Hazardous Locations
Food Grade NSF

High Temperature: We have 80C and 90C high ambient temperature options and can replace 250W, 400W and 1000W HID. These lights are rugged and designed to operate in higher temperature environments.

Hazardous Location: Have volatile explosive or dusty environments? We have C1D1 and C1D2 UL844 rated explosion proof high bays.

Food Grade NSF: We have NSF certified LED High Bays for food processing and beverage facilities.

9. Reduce energy costs up to 75%


Our energy-efficient indoor high-bays reduce commercial costs and becomes practical and sustainable. With energy savings up to 75%, you can reduce a tremendous amount of energy consumption. LEDs have longer lifespans. We can add motion sensors to turn off or dim the light source when no activity is detected.

10. Decrease maintenance costs


Our efficient LED bay lights have L70 ratings that last upwards of 100,000+ hours. Less bulb replacement saves costs in factories and warehouses. This cost saver is often overlooked, but saves a tremendous amount of money.

11. Rugged fixtures will last years!


Our bay fixtures withstand extreme cold and hot temperatures without decreasing lifespan. This is possible through our large heat sinks, designed to keep the lights cool. UFO fixtures have heavy duty heat sinks that are perfect for impact zones. Our bay fixtures are vibration resistant. This allows them to maintain a long lifespan in harsh environments.

12. Easily convert F54T5HO to LED


Tired of changing tubes? Tired of tubes that don't last as long as they should? Replacing F54T5HO Fluorescent fixtures is simple and easy. Each T5 tube produces approximately 4000 lumens each. The light is not directional, so effective lumens is less than the 24,000 combined lumens for a 6 tube fixture. We replace these fixtures with a cost effective, maintenance free equal LED solution.

Photometrics - Get it Right before you buy

Why are photometrics important? They allow you to see your area and how it would look under LED Lighting taking the risk out of buying. We can easily run different options with our lights, and provide you with the proper information and guidance. We're here to save you money with LED. But it's as important to get the lighting right. 

Why Are LED High Bays Superior to Metal Halide and Fluorescent Lights?

Better Lumen Intensity

The modernization of today's light source has created an improvement in energy efficiency. Thanks to the innovative technologies in the lighting industry. The use of LEDs along with the controls that work with them are now efficient to consume less energy. This translates into a large reduction in the cost of lighting.

Here are the details on how LEDs have better lumen intensity than HID lamps.

1. 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 doesn't mean the light has failed. It means that the usefulness of the light has diminished. HID are notorious for being bright brand new and fade over time. Switch on the lights for the first time and measure initial lumens for LED lights after 45 minutes. Calculate initial lumens in HID light bulbs after 1,000 hours of initial use.

2. Lumen Maintenance and L50, L70 and L90 Rating

Lumen maintenance relates 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 light intensity fades, rendering the luminaries obsolete and inefficient.

Lighting experts use the ratings to estimate the amount of light the LED diodes produce. When the fixtures diffuse by 50% the number of initial lumens it's called L50, with 70% as L70 and 90% L90.

The L70 rating is the most popular. It indicates the point at which LEDs lose 30% of their lumen intensity while maintaining 70%. Look at the LED product specifications. 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. Yet, these components, in well designed LED products, are easy to replace.

The human eye notices the decline at 70% deterioration of light output. Yet, the human eye is only affected when the light intensity of a light source reaches a level of 30%.

When a fixture states it has 50,000 hour lumen maintenance, it means that you'll notice a decrease in intensity after 50,000 hours. But don't take this to mean that the fixture will stop functioning.

3. Delivered Lumens

Delivered or absolute lumens, describes flux produced by a light source which includes an optical loss factor. Optical loss is not included in the calculation when it comes to traditional HID High Bays. Including delivered lumens is very important. This is because HID lamps do not deliver the same amount of lumens they produce. This is key when you compare the specification of an HID High Bay and a LED High Bay. What you think you get with an HID High Bay is not what's as advertised.

But when it comes to LEDs, the story is different. When LED fixtures 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.

Examine a variety of factors when comparing the light output of an HID lamp with that of a LED lamp. Look at lifespan, optical loss factor (particularly for HID lights) and lumen maintenance.

In a nutshell, high bay LEDs have better light intensity when comparing HID luminous flux to LEDs. 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.
