Retrofit Washdown Round Bay Lights

Upgrade your existing bay lights to energy-efficient LEDs without replacing your mounting hood or conduit. These lights are NEMA 4X rated, so they’re sealed to withstand sprayed water and cleaning chemicals from washdowns. They’re also UL marine listed to resist corrosion from salt water. IP66 and IP67 rated, they’re dust tight. Even in extreme temperatures, from -40° F to 145° F, they keep shining.
Styles B and C require an adapter (sold separately) to fit into Crouse-Hinds, Killark, and Mercmaster mounting hoods. Rated IK08 for impact resistance, they’re strong enough to take a hit without cracking.

Retrofit Hazardous Location Round Bay Lights

Upgrade your existing hazardous location bay lights to energy-efficient LEDs. Choose a light that matches the model already in place—they’ll fit into your existing hood and connect to the wires already in your conduit. Safe to use in areas with combustible concentrations of gases, vapors, dust, and fibers, these lights are rated NEC Class I, II, and III.
These lights even stand up in wet and outdoor locations. Rated IP66 and IP67, they withstand washdowns and submersion in water. They’re also dust tight. For resisting salt water and other corrosive liquids, they’re UL marine listed and NEMA 4X rated. They’ll keep shining in extreme temperatures, from -40° F to 145° F.
Style B and C require an adapter (sold separately) to fit into Crouse-Hinds, Killark, and Mercmaster mounting hoods.
