An incandescent filament lamp is the light source most commonly used in residential lighting. Light is produced in this source by a wire or filament being heated to incandescence by a flow of current through it. The short life and low efficacy (lumens per watt) of this source limits its use mostly to residential and decorative commercial lighting.

Efficacy varies with wattage and filament type, but generally ranges from 12 to 25 lumens per watt for general service lamps. The incandescent source does, however, produce a highly accepted warm color and provides instant-on lighting. It is more convenient than other light sources because it can be run directly on line current and therefore does not require a ballast. It can be dimmed using relatively simple equipment. It is also available in different bulb sizes, shapes and distributions to add a decorative touch to an area.
