Halogen light bulb Halogen bulbs provide an intense, white light in a very small "envelope" or casing. They're used in a range of lighting products, from flashlights to aircraft running lights. In the home, they appear in some torchiere-style floor lamps, reading lights, grow lights, slide projectors, outdoor lights, and similar products.

Because halogen bulbs burn very hot, they can present a serious fire hazard if not used properly.
