Linear High Bay Lights

Standard linear high bays can replace outdated fluorescent and metal halide fixtures or be used in new installations. They illuminate large spaces, including factories, warehouses, and grocery stores. 

High-temperature linear high bays can be installed in warmer environments and won’t fail due to high heat. These linear LED light fixtures can operate in temperatures as high as 149°F, so they’re ideal for warehouses, distribution centers, cafeterias, and other areas subject to higher temperatures. 

We offer NSF washdown linear high bays. These high bay linear LED lights are IP69K rated, so they can handle high-pressure washdowns. The National Sanitation Foundation (NSF) has certified these fixtures for installation in controlled environments and food zone non-contact, splash zone, and non-food zone areas. These are usually installed in food processing plants, industrial kitchens, and sanitary areas. 

Sensor-ready linear high bays can be installed with compatible sensors to save energy. You can install a microwave motion sensor or a PIR motion sensor. Microwave motion sensors can detect people and other types of movement, like a forklift, and can detect through shelves or other equipment. PIR sensors mainly detect people and have a setting available to set a customized time for the lights to remain on after detecting motion. Some motion sensors might use photocells to turn the lights on and off for dusk to dawn operation. Certain products also come adapted with daylight harvesting, meaning they use photocells to detect the amount of ambient light in the space to adjust the light output and dim accordingly. You can enhance your sensor-ready linear high bays with Network Lighting Controls using our Keilton PIR Daylight Harvesting Motion Sensor. This motion sensor is activated with an app, allowing for wireless communication. If you choose to install multiple of these motion sensors, you will be able to control them all at once.

The height of your ceiling and the size of the room will help determine how many linear bays you should install and how far apart to space them. A light covers more area as ceiling height increases. Therefore, the higher the ceilings, the farther apart you can space the lights. Install more light fixtures in lower ceilings to ensure even light distribution with no glare. However, to ensure enough light intensity, you should increase the wattage and lumens of the fixture as the ceiling height is increased. We typically recommend ceilings under 20 feet to space lights 12-15 feet apart, between 20-30 feet to space lights 15-20 feet apart, and ceilings taller than 30 feet to space lights 20-30 feet apart. The image below illustrates light distribution as height increases.

Consider what wattage you need. Each of our products lists the wattage equivalent of a metal halide. For example, a high bay labeled ‘85W LED Linear High Bay - 11,900 Lumens - 250W MH Equivalent’  has the same amount of lumens as a 250-watt metal halide bulb, but only consumes 85 watts. Because of this, it is easier to compare fixtures based on the lumen count. 

You should also consider the CCT you want for your high bays. We sell high bays with a CCT of 4000K (more of a natural white) and 5000K (a cool white). A few of our products come with selectable CCTs so you can choose between the two CCTs based on your preference. 

The beam angle of the high bay will also affect light distribution. Most linear high bays feature medium-wide to wide beam angles, ranging from 90° to 120°. This ensures even light distribution throughout the area. 

All linear high bay lights must be installed by a verified electrician. The exact installation will vary depending on the mounting kit you choose. Check out the user manual for specific details regarding installation.
