    Halogen bulbs are incandescent bulbs, but they differ from regular incandescent bulbs because they contain a gas with traces of halogen that protects the filament. The tungsten filament in a regular bulb gradually evaporates until it breaks. In a halogen bulb, however, the halogen recombines with the evaporating tungsten and returns it to the filament, thus greatly extending the filament's life.

    On the Other: A More Efficient Incandescent Bulb

    Because of the way the halogen restores the tungsten filament, the halogen bulb operates at a higher temperature than a regular bulb. This produces a brighter light that improves upon the energy efficiency of regular bulbs by 10 percent to 20 percent, depending on the quality of the gas that the halogen bulb contains.

    Bottom Line

    Halogen is an efficient form of incandescent lighting, but it still dissipates most of its energy as heat. If your priority is efficiency, fluorescent lighting would be more effective. Fluorescent lights are 300 percent to 500 percent more efficient than incandescent lights.
