Abbreviated as halogen bulb or halogen lamp, also known as tungsten halogen bulb, quartz bulb, it is a variant of incandescent lamp.
The principle is to inject halogen gas such as iodine or bromine into the bulb. At high temperature, the sublimated tungsten wire chemically reacts with the halogen. The cooled tungsten will re-solidify on the tungsten wire to form a balanced cycle to prevent the tungsten wire from breaking prematurely. Therefore halogen bulbs last longer than incandescent bulbs.
The supply voltage of halogen lamps is usually divided into two types: AC 220V, DC 12V and 24V.
