Halogen bulbs get their name from the type of gas that is encased within the glass bulb. Comparison Halogen light bulbs look and function much in the same way as incandescent light bulbs. They feature a glass bulb that contains an oxygen free environment. A tungsten filament is mounted in the center and the whole bulb is attached to a metal base that screws into a light fixture. The key difference between other incandescent bulbs and a halogen bulb is that the bulb is filled with Halogen gas while incandescent bulbs are generally filled with argon gas. The halogen gas is contained in a small pressurized bulb that is encased in a larger outer glass bulb. In between the two layers of glass is krypton, which helps to slow down the evaporation of the tungsten; the tungsten evaporates due to the heat produced by the
