CFL
Energy-saving bulb
CFL is an abbreviation with two common meanings.
A CFL is a compact fluorescent lamp—the spiral-shaped energy-efficient light bulb that largely replaced incandescent bulbs before LEDs took over: We switched all the CFLs to LEDs.
The CFL is also the Canadian Football League, the professional football league in Canada playing a variant of American football with a larger field and three downs.
