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.

Portable Bay Lights


Light up large, open rooms where you need a quick setup and takedown, such as a room under construction. Just hang these lights from a ceiling up to 30' high and they’re ready to go. Connect up to 10 lights on a single circuit. The brighter the light, the further you should space them apart. All withstand humidity and moisture, so you can use them where it’s damp.
Lights with an outward beam direction have straight sides, so they’ll direct some light to the ceilings and walls of your facility. Rated IP64, they’re sealed against splashing liquid and dusty conditions.
Lights with a downward beam direction have angled sides, so they’ll direct more light towards the floor than lights with an outward beam direction.
