Incandescent E-12 Bulbs
E-12 Candelabra Base Incandescent Light Bulbs
E12 is the smaller candelabra base. It's commonly used for nightlight bulbs, and sometimes for decorative light bulbs used in chandeliers and over bathroom mirrors.
The incandescent light bulb or lamp is a source of electric light that works by incandescence, which is the emission of light caused by heating the filament. They are made in an extremely wide range of sizes, wattages, and voltages.
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.
