What are LED Lighting Supply Linear High Bays?

LED linear high bay fixtures are panel-style indoor fixtures that replace F54/T5/HO or T8 fluorescent systems in high-ceiling applications. These rectangular fixtures feature LED strips embedded on the back panel to deliver uniform illumination throughout large spaces. Wire or chain mounting provides the most secure installation, though pendant options work well for specific layouts.

Wide light distribution characterizes linear high bays, creating even coverage without hot spots or dark areas. The panel design doesn't accommodate narrow beam optics like UFO fixtures, making them ideal for ceiling heights up to 35 feet. We offer these fixtures in 100-277V standard voltage and 277-480V high voltage configurations, plus color-adjustable and wattage-adjustable models for maximum flexibility.
