How Halogen Lamps Work
Halogen lamp function through a process similar to traditional incandescent bulbs but with some key differences that enhance performance. Inside a haloge lamp, an electric current passes through a tungsten filament, heating it to a high temperature until it glows and emits light. The halogen gas within the bulb, typically iodine or bromine, creates a chemical reaction with the tungsten vapor. This reaction redeposits evaporated tungsten back onto the filament, significantly extending its life and maintaining the clarity of the bulb. This recycling process allows the lamp to operate at higher temperatures, resulting in a brighter and more efficient light output compared to conventional incandescent lamps.
