Brighten large, open areas, such as warehouses and manufacturing spaces. Use them to replace old high-intensity discharge (HID) lights—they’ll hang from the same chain. IP rated and UL listed for wet locations, these lights are sealed against washdowns. They’ll also keep out dust. The lens is made of polycarbonate to resist impact. These lights are also known as UFO lights.

Lights rated IP65 are protected against low-pressure washdowns. Styles B, C, and D last longer when used at high temperatures than Style A, thanks to larger heat sinks and thermally protected drivers. Each light has exactly the same light appearance, so they’ll look the same if you’re using multiple. For a rigid mount, you can thread them onto conduit. Add a motion sensor (sold separately) so your light only turns on when there’s movement, saving energy.
