Metal Halide Light Bulbs
Illuminate large warehouses, factories, and arenas with the bright, white light of these metal halide bulbs. Brightness is measured in lumens; the higher the lumens, the brighter the bulb. Color rendering index (CRI) is a measurement on a scale of 0-100 of how accurately the light from a bulb represents an object's true colors; the higher the number, the more natural the colors appear. Any CRI value over 80 will show colors true to life. A bulb’s estimated yearly cost is based on 3 hours of usage per day at $0.11 per kWh.
Bulbs with an EX39 base number will not burst when they fail.
Pulse-start bulbs restart nearly twice as fast as probe-start bulbs.
Bulbs that cannot be sold to the listed areas exceed local regulatory limits on mercury content.

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.
Plug socket-ready bulbs into an existing fixture with a compatible ballast.
