    Abstract: A halogen bulb having a tungsten filament and containing a reactive carrier gas mixture including halogen, as well as an inert gas in a transparent envelope to repeatedly regenerate tungsten evaporated from the filament during operation. Improvement lies in using hydrogen bromide and ammonium bromide as the reactive carrier gas mixture, thereby providing a bulb of high efficiency, and uniformly long service life.
