CFL means compact fluorescent lamp (CFL), a type of
fluorescent lamp.CFLs contain argon and mercury vapor housed
within a tube.
In a CFL, an electric current is driven through a tube containing
argon and a small amount of mercury vapor. This generates
invisible ultraviolet light that excites a fluorescent coating
(called phosphor) on the inside of the tube, which then emits
visible light.
