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.

Mercury Vapor Light Bulbs

Blown Tubular

A traditional bulb type often found in older high-intensity discharge (HID) fixtures, these bulbs emit light with a blue/green tint. Use them to illuminate large outdoor areas, such as parking lots. 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.

Metal Halide Light Bulbs for High-Pressure Sodium Lights

Blown Tubular Bulb with E39 Base

Cone Bulb with EX39 Base

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.

Bulbs with an EX39 base number will not burst when they fail.
