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.

Hazardous Location Linear Bay Lights
Mount these lights in large, open areas where flammable and combustible gases may be present, such as during leaks or ventilation failures. These lights are rated for use in NEC Class 1, Division 2 hazardous locations. They meet NEC hazardous location temperature classifications, so their surface stays cool enough to avoid igniting hazardous gases. All are IP rated and UL marine listed, which confirms they also keep out dust and water and resist the corrosive effects of salt water. Mount them to your ceiling or wall with the included bracket.
For additional protection, choose a light rated for more NEC classes. NEC Class II-rated lights protect against flammable and combustible dust. NEC Class III-rated lights protect against flammable and combustible fibers.
Style 1 are IK08 rated—they'll withstand impact. They have a tempered glass lens that resists scratches better than a polycarbonate lens. All are ETL and C-ETL listed to meet U.S. and Canadian safety standards. To hang them from the ceiling, add suspension hardware or combine them with a pendant mount and junction box (all sold separately).
