fluorescent bulbs

Gas-discharge light tubes

Fluorescent bulbs are electric lights that produce illumination by passing current through gas-filled tubes, causing a phosphor coating to glow.

They use less energy than incandescent bulbs and last longer, though they contain small amounts of mercury.

The characteristic cool, slightly bluish light became ubiquitous in offices and schools: The fluorescent bulbs hummed overhead.
