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

Tubular Bulb with E26 or EX39 Base

Mogul

Medium (Standard Household)

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.

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

For Bay Lights

For Floodlights

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.
