Or as low as 
A halogen lamp or tungsten halogen lamp is a type incandescent lamp. The halogen lamp consists of a tungsten filament enclosed in an environment of an inert gas like argon and a small amount of a halogen like bromine or iodine. The combination of the tungsten filament and the halogen results in a chemical reaction (called regenerative cycle or halogen cycle).
This regenerative cycle increases the life span of the filament. Also, the halogen cycle prevents the darkening of the lamp envelope by redepositing the tungsten from the inside of the lamp back onto the filament and It gives brilliant light from a compact unit.
The use of halogen gas at low pressure in the lamp reduces the uneven evaporation of the filament. The halogen lamps can operate at a higher temperature than a standard gas filled incandescent lamp of the similar power rating without loss of its operating life.
The halogen light lamp uses a halogen gas in order to increase both light output and rated life. They are known for moderately high efficiency, quality of light, and high rated life compared to regular incandescent lamps.
Uses
- Widely used in automobiles as headlamps.
- Infrared light source.
- Stage lighting.
- Projection lamps in motion pictures and slide projectors.
- under-cabinet lighting
- Work lights
- Halogen reflectors like MR and PAR lamps are often preferred for directed lighting such as spotlights and floodlights.
