fluorescent lamps
Gas-discharge light tubes
Fluorescent lamps are electric lights that produce illumination by passing current through a gas-filled tube, causing a phosphor coating to glow.
More energy-efficient than incandescent bulbs, they dominated office and commercial lighting for decades.
The characteristic cool, slightly buzzing light became synonymous with institutional spaces: the harsh fluorescent lamps of the waiting room.
