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.
Plastic-coated glass bulbs are shatter resistant; the coating retains glass shards if they break.
Bulbs that cannot be sold to the listed areas exceed local regulatory limits on mercury content.

Metal Halide Light Bulbs for High-Pressure Sodium Lights
Switch from the yellow light of high-pressure sodium to the white light of metal halide without changing ballasts. 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.
