wolfram lamp

Incandescent @L03447@ that generates light by passing an @E01927@ through a thin filament wire (usually of wolfram) until it is extremely hot. The lamps are often filled by a halogen gas such as iodine and bromine that allow filaments to work at higher temperatures and higher efficiencies.
