Scientific definitions for fluorescent lamp

fluorescent lamp

[ flu-rĕs′ənt ]

An electric lamp that produces light through fluorescence. In most fluorescent lamps, a mixture of argon and mercury gas contained in a glass bulb is stimulated by an electric current, producing ultraviolet rays. These rays strike a fluorescent phosphor coating on the interior surface of the bulb, causing it to emit visible light. Fluorescent lamps are much more efficient than incandescent lamps because very little energy is lost as heat. Compare incandescent lamp.
