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 IP65 are protected against low-pressure washdowns. Style A are often used in smaller spaces such as garages and workshops. Those with a NEMA 5-15 plug don’t need any wiring. Just plug them in to a standard outlet.

High-Temperature Linear Bay Lights

Rated for over a decade of use well above 100° F, these linear bay lights long outlast standard facility lights in high heat. They’re often installed in warehouses located in sweltering climates and in fiery manufacturing facilities, such as steel mills.
Style B lights are rated IP66 for protection from washdowns. They're also rated IK10—the highest rating for electrical equipment—and offer four times the impact resistance of Style A lights. Mount them using the included bracket and eyebolt.

Corrosion-Resistant Washdown Bay Lights


Illuminate harsh, wet areas, even outside in extreme weather—these lights are often used on ship building ports. Rated NEMA 4X and UL marine listed, they’re sealed against heavy rain and washdowns, and they won’t corrode from salt water or cleaning chemicals. They’re also IP rated to stay sealed in dusty conditions. And with a durable glass lens, they’re rated IK08 for impact resistance. They’ll work in temperatures from -40° F to 145° F. Bright enough for environments that require high visibility, these lights have a cool appearance that highlights white and blue tones.
A quick-connect mount lets you wire these lights to an outlet box without having to hold them in place. First, wire the mount to your outlet box with a 3/4" conduit connector. Then twist the light into the mount to lock it in place.
These lights are DLC (DesignLight Consortium) listed, so they’ve been tested to confirm their energy efficiency. They’re also CE Marked to meet European safety standards.

LED Light Bulbs for High-Intensity Discharge (HID) Lights


Replace high-intensity discharge (HID) lights with the longer-lasting, energy-efficient LEDs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. LED lights are perceived as brighter at night than high-intensity discharge light technologies, so they require fewer lumens to provide the same brightness. Match your old light’s wattage to find the right LED bulb. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
Ballast bypass bulbs eliminate the need for a ballast, so the socket must be wired directly to the power source.
