fluorescent light

Glowing gas tube

A fluorescent light is a tube-shaped lamp that produces light by passing electricity through mercury vapor, causing a phosphor coating to glow.

Fluorescent lights are more energy-efficient than incandescent bulbs but cast a flat, often unflattering light associated with offices, schools, and institutional spaces: The fluorescent lights hummed overhead.

The adjective fluorescent describes the greenish-white quality of this illumination.
