High-output lamps operate at 800 mA, and some types operate up to 1.5 A. The power level varies from 33 to 82 watts per meter of tube length (10 to 25 W/ft) for T12 lamps. [32] The simplest ballast for alternating current (AC) use is an inductor placed in series, consisting of a winding on a laminated magnetic core.
An electric light, lamp, or light bulb is an electrical component that produces light.It is the most common form of artificial lighting.Lamps usually have a base made of ceramic, metal, glass, or plastic which secures the lamp in the socket of a light fixture, which is often called a "lamp" as well.
