Find the right lumen level to brighten your space. Then, compare the way warm, neutral, and cool lighting affect the appearance of everyday objects.
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.

Linear Bay Lights
With more surface area than round bay lights, these fixtures produce softer light with less glare. Use them to replace old fluorescent lights and illuminate large, open areas with high ceilings. Rated for use in damp locations, these lights withstand humidity and moisture.
Styles B-D have thermally protected drivers and larger heat sinks than other bay lights, so they’ll last longer at higher temperatures. Their LEDs have a consistent color temperature, which helps maintain a uniform appearance across multiple lights.
Style B lights are compatible with an emergency backup battery (sold separately), so they’ll stay lit for 90 minutes if the power goes out. The battery meets UL 924 standards.

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. For lights with mounting V-hooks, you can suspend them from the ceiling with chains (not included).
Styles A-B have a wraparound lens that allows light to shine from the sides as well as the bottom. Lights with a backup battery stay illuminated for at least 90 minutes during a power outage in compliance with UL 924.
IP65 lights withstand light rinses. NEMA 4X lights withstand corrosive liquids and spraying water—including washdowns.
Lights that meet NSF/ANSI 2 standards are commonly used in food handling and processing areas with splashing liquid.
