CFL bulb

Coiled fluorescent light

A CFL bulb is a compact fluorescent lamp—a type of energy-efficient light bulb that uses a fraction of the electricity of traditional incandescent bulbs.

The tube is folded or coiled to fit standard light fixtures.

CFLs dominated the energy-efficient lighting market before LED bulbs largely replaced them.

We switched all our CFL bulbs to LEDs.
