     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.
