Linear Bay Lights
With a lower profile design than other bay lights, linear bay lights mount closer to ceilings, providing more room for racks or shelving. Use them in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 40 ft. high. Rated for use in damp locations, these lights withstand humidity and moisture. They can be hardwired to operate on any of the voltages listed.
Style A and C lights require suspension hardware (sold separately), which includes two wire rope slings with hooks and two wire rope clamps. No tools required—adjust the length of the suspension hardware and tighten the clamps to secure. Style B lights come with suspension hardware: two V-hanger brackets and two 36 in. chains.
Lights with built-in LEDs last longer, are more efficient, and generate less heat than fluorescent lights. They emit a neutral white light often found in workspaces. All have a lens that disperses light evenly.
Lights without bulbs work with tubular fluorescent bulbs (sold separately).
Lights with an aluminum housing are lightweight and resist corrosion better than those with a steel housing. Lights with a steel housing are more durable than lights with an aluminum housing.

Bay Lights
Use these lights in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 30-ft. high. Rated for use in damp locations, these lights withstand humidity and moisture. Lights have built-in LEDs, which last longer, are more efficient, and generate less heat than other light technologies. They emit a neutral white light often found in workspaces. Lights can be hardwired to operate on any of the voltages listed. Thread onto 3/4 NPT conduit to mount lights to the ceiling.

Hazardous Location Bay Lights
Use these lights in large, open areas such as warehouses and manufacturing spaces where the ceiling is up to 30-ft. high. They are ETL and C-ETL listed for Class I Division 2 Groups A, B, C, and D, Class II Divisions 1 and 2, Groups E, F, and G, and Class III Divisions 1 and 2 for use in environments where ignitable concentrations of acetylene, hydrogen, ethylene, and propane occur infrequently, such as in the case of an accidental spill or failure of a ventilation system. With built-in LEDs, these lights last longer, are more efficient, and generate less heat than other light technologies. They produce a neutral light appearance, which creates a balanced environment for general work areas. These lights produce a wide beam of uniform light. Lights can be hardwired to operate on any of the voltages listed. Thread onto 3/4 NPT conduit to suspend lights from the ceiling.
