- Halogen Light Bulb
A type of incandescent light bulb that lasts much longer and is more efficient than a standard incandescent light bulb. The light bulb uses a halogen gas, usually iodine or bromine, that causes the evaporating tungsten to be redeposited on the filament, thus prolonging its life. Halogen lamps produce a brighter, whiter light than standard incandescent. They are especially suited to recessed or"canned fixtures,"track lights, and outdoor lights.
