Frequently Asked Questions

We spoke with first-time buyers and repeat customers to find out their biggest questions when it comes to buying Linear LED Bay Fixtures. For more information, please call us at (888) 423-3191 and one of our lighting experts will be able to assist you.

What are LED Linear Bay Fixtures?

Linear Bays are a panel style indoor fixtures that resembles the old style F54/T5/HO or T8 fluorescent light its designed to replace. They are square or rectangular in shape and contain strips of LEDs embedded on the back of the fixture to provide the light source for higher ceilings applications.

Distribution is typically wide. By design, it is not often you will see an option to narrow down the beam angle with optics on these fixtures since the design does not easily accommodate optics.

For lower ceiling applications, we also offer linear low bay fixtures.

How Do Linear LED Bay Fixtures differ from traditional (fluorescent) light fixtures?

There are many differences between LED and fluorescent fixtures. Here are what we believe are the major differences between them:

Energy savings: You should expect upwards of 50% reduced energy costs when using linear LED bay fixtures over fluorescent linear lighting. There are additional energy efficiency savings when controls like motion sensors are used.
Lower Maintenance Costs: Depending on the quality of the product, fluorescent tubes can operate for 15,000 to 30,000 hours.
No strobing or humming: Fluorescent lights always strobe. Near the end of life, it’s very noticeable.  This strobing can cause eye strain and headaches. And fluorescent ballasts hum, and this becomes quite loud near the end of the ballast’s life. With LED, no strobing or humming.
LEDs are Instant On and Instant Off: Fluorescents are also quick, but take some time to warm up. This becomes a lot longer if the room they are installed in is cold.
Works well with motion sensors. LED Linear Fixtures turn on and off quickly – and dim – so they work well with these energy savings controls. You need special ballasts to do this with fluorescent lighting.
Dimming: Most LEDs (not all) can dim. In warehouses, this means you can dim the lighting when the space is empty. They work perfectly with dimming motion sensors. Fluorescent lighting needs special ballasts to dim.
Recycling: With LED, there are no expensive recycling processes because LEDs do not contain mercury or other harmful substances.

What are the best applications for linear bay fixtures?

These lights are great for many commercial and industrial indoor spaces. We have customers who purchased these LED Fixtures for:

factories and manufacturing facilities
aircraft hangars
industrial spaces
conference halls and event centers
rec facilities, gyms, and fitness centers
retail stores

How many LED lumens would you recommend to replace fluorescent fixtures?

Below is a chart for the replacement of F54/T5/HO tubes with energy-efficient LED Fixtures. The actual lumens required will differ depending on the fixture’s mounting height.

Fluorescent Fixture LED Lumens Equivalent
4 tube F54/T5/HO 12,000 to 18,000 lumens
6 tube F54/T5/HO 18,000 to 24,000 lumens
8 tube F54/T5/HO 24,000 to 40,000 lumens


How do I Replace Fluorescent Lighting with your LED Fixtures?

Replacing linear lighting fixtures is quite simple. We can replace fluorescent fixtures with LED one-for-one. So, there is no need to add more lights.

Our lights hang the same way fluorescent fixtures do. They mount by pendant mount or chain mounting / wire cables. They hook up to the power source and have only 3 wires to connect – line, neutral, and ground.

What are the lumen output and color temperatures available for LED Fixtures?

The color temperatures we recommend, and stock are 5000K and 4000K color temperature. Most customers ask for 5000K for commercial and industrial applications.

Our LED linear-bay fixtures produce between 13,000 and 65,000 lumens. In terms of replacement, we can easily replace 4, 6, 8, and 10 tube T5 fixtures, as well as 400-Watt to 1500-Watt Metal Halide.

Can Linear Linear High Bay Fixtures be used in wet or damp locations?

Some of our linear fixtures are damp location rated, but none should be used in a wet location. We would recommend UFO Fixtures instead if the location you are installing the lights at is wet.
