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

For Bay Lights
Swap out the high-intensity discharge (HID) bulbs in your hazardous-location lights to lower energy costs. These LED bulbs are rated for NEC Class I, Division 2 locations, so they’re safe to use near combustible concentrations of gas. They last longer than HID bulbs and achieve the same brightness with fewer lumens. Match the wattage of the bulb you’re replacing. These are ballast bypass bulbs—install them in a socket that’s wired directly to the power source.
