Tungsten Halogen Lamps
Tungsten halogen lamps—a type of incandescent lighting—achieve better energy efficiency than standard, incandescent A-type light bulbs.
Tungsten halogen lamps have a gas filling and an inner coating that reflect heat. Together, the filling and coating recycle heat to keep the filament hot with less electricity.
These lamps provide excellent color rendition. They also are considerably more expensive to buy than standard incandescent lamps, but are less expensive to operate because of their higher efficacy.
