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, 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. Style D are the best choice for food environments that require sanitizing washdowns. They’re domed so water drains off and debris doesn’t settle.
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.

Washdown Ceiling Lights
IP or NEMA rated, these lights have a sealed lens to keep dust and moisture out for protection against washdowns. All meet ETL or UL standards for wet locations.
Mount these lights to the ceiling with the included brackets.
Styles A-B have a wraparound lens that allows light to shine from the sides as well as the bottom.
Style C have a tubular lens that allows light to shine from all directions. Those made outside of the U.S. include power connectors to link two lights. On the same circuit, link up to 62 of the 20W lights, or up to 27 of the 50W lights. Once connected, the lights can no longer be dimmed. They also include cables for ceiling suspension. IP66 lights withstand high-pressure washdowns. IP67 lights withstand temporary submersion, so they’ll handle your wettest areas. IP69K lights withstand high-temperature, high-pressure washdowns often used in sanitizing. NEMA 4X lights withstand corrosive liquids and spraying water—including washdowns. IK10 lights have the highest impact resistance rating.
Lights that meet NSF/ANSI 2 standards are commonly used in food handling and processing areas with splashing liquid.
