Abstract: 

CFLs are known as compact fluorescent lights or compact fluorescent light bulbs. In a CFL, an electric current is driven through a glass 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.
