A55 Incandescent Bulb

Item No.: 031

An incandescent bulb typically consists of a glass enclosure containing a tungsten filament. An electric current passes through the filament, heating it to a temperature that produces light.
Incandescent light bulbs usually contain a stem or glass mount attached to the bulb's base which allows the electrical contacts to run through the envelope without gas/air leaks. Small wires embedded in the stem support the filament and/or its lead wires.
The enclosing glass enclosure contains either a vacuum or an inert gas to preserve and protect the filament from evaporating.
