Tung·sten lamp. An electric glow lamp having filaments of metallic tungsten, and contained in a glass bulb which is evacuated or has an inert gas, to avoid oxidation of the tungsten; a common form of light bulb. Such lamps, owing to the refractory nature of the metal, may be maintained at a very high temperature and require an expenditure of only about 1.25 watts per candle power, depending on the total wattage and the design of the bulb.  By mid-20th century tungsten lamps became the most common type of incandescent (as contrasted with fluorescent) lamp; thus the phrase incandescent lamp or incandescent light typically refers to a tungsten lamp.

 Incandescent lamp, Incandescent light, Incandescent light bulb Elec., a kind of lamp in which the light is produced by a thin filament of conducting material, now usually tungsten, but originally carbon, contained in a vacuum or an atmosphere of inert gas within a glass bulb, and heated to incandescence by an electric current. It was inventerd by Thomas Edison, and was once called the Edison lamp; -- called also incandescence lamp, and glowlamp.  This is one of the two most common sources of electric light, the other being the fluorescent light, fluorescent lamp or fluorescent bulb.
