A sizable portion of the energy is lost as heat along with the yellowish appearance of the light that is emitted. The tungsten filament heats up to a temperature of between 3,140 and 4,940 degrees Fahrenheit when an electrical current is supplied to it. Incandescent BulbsĪ sealed glass bulb that contains a tungsten metal filament and is either evacuated or filled with an inert gas to prevent burning is an incandescent bulb. The two most frequently used types of lighting fixtures in most homes are incandescent bulbs and fluorescent lamps. Compared to a fluorescent light, an incandescent bulb emits less light and generates more heat. In contrast, incandescent bulbs use this heat to produce their light. Unlike fluorescent lamps, which operate by fusing gaseous atoms and electrons to produce ultraviolet light, incandescent bulbs use electricity to create heat that causes the filament to glow and emit light.
