fluorescent bulb
Gas-discharge light source
A fluorescent bulb is a tube-shaped light that produces illumination by passing electric current through mercury vapor, which emits ultraviolet light that causes a phosphor coating to glow.
Fluorescent bulbs use less energy and last longer than incandescent bulbs but contain small amounts of mercury.
The long tubes in office ceilings and the spiral compact fluorescent lamps (CFLs) for home use are both fluorescent bulbs.
