incandescent lamp

in·can·des·cent lamp

(ĭn′kən-dĕs′ənt)
A lamp that produces light by heating up a filament of wire inside a bulb with an electric current. Because the filament, usually made of tungsten, would burn from the heat, the bulb is filled with a nonreactive gas, such as argon, which protects the wire from burning. Compare fluorescent lamp.
