Round Bay Lights

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 IP66 are protected against high-pressure washdowns. Lights rated IP69K are protected against high-temperature, high-pressure washdowns, such as those used for sanitizing. Lights rated NEMA 4X are protected against washdowns and corrosive liquids.
Lights that meet NSF/ANSI 2 splash zone are safe to use in food processing areas with splashing liquid.
Styles B, C, D, and E 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. Styles B, C, and D can be threaded onto a conduit to create and rigid mount. Styles D and E are the best choice for food environments that require sanitizing washdowns. They’re domed so water drains off and debris doesn’t settle.
Add a motion sensor (sold separately) so your light only turns on when there’s movement, saving energy.
Add an emergency backup battery (sold separately) to keep your light running if the power goes out. They help your light meet UL 924, which ensures it will stay powered for at least 90 minutes during an outage.

Outdoor Ceiling Lights
Hang these lights in garages and covered walkways to create a safe, well-lit path. They’re also known as canopy lights. All are either UL or ETL Listed for use in wet locations. Select a light appearance to match your existing lighting. If you’re not sure what temperature you need, choose a light with a selectable light appearance. You can adjust the temperature with a switch.
Fasten these lights to a ceiling or to an outlet box. Styles A-C can also be suspended like a pendant from conduit.
Lights with a light sensor automatically turn on in low light conditions. Lights with a motion sensor stay dim until movement is detected, saving energy.
Lights rated IP65 are sealed to keep out dust and driving rain.
