Thermographic infrared images of electric bulbs
An electric light is a device that produces visible light by the flow of electric current. It is the most common form of artificial lighting, providing interior lighting for buildings and exterior light for evening and nighttime activities. In technical usage, a replaceable component that produces light from electricity is called a lamp. Compact lamps are commonly called light bulbs; for example, the incandescent light bulb. Lamps usually have a base made of ceramic, metal, glass or plastic, which secures the lamp in the socket of a light fixture.
Three categories are actually existing: incandescent, gas-discharge and Light-emitting diod.
