  • Driving Halogen Lamps by Brenda Kovacevic

    A halogen lamp operates in the same manner, except that a small amount of halogen gas has been added to the fill gas; this halogen is normally bromine. When the bulb wall temperature reaches roughly 250 °C, the "halogen regenera-tive cycle" begins to take place. The evaporated tungsten molecules now combine with the free halogens to form a

  • Halogen vs. Xenon headlights. What are the differences?

    The halogen gas lets the filament temperature rise until it almost at the melting point of tungsten (3400°). The result is a high output of light. It has the side effect of extending the lifespan of the bulb. The evaporated tungsten forms a gas which mixes with the halogen gas in the lightbulb and forms tungsten …
