WebCompact fluorescent lamp (CFL) and light-emitting diode (LED) light bulbs last substantially longer than incandescent light bulbs, reducing labor costs of replacing light bulbs. Coal-burning power plants emit mercury into the environment; using ENERGY STAR light bulbs can reduce these emissions. WebDec 7, 2001 · The central element in a fluorescent lamp is a sealed glass tube. The tube contains a small bit of mercury and an inert gas, typically argon, kept under very low pressure. The tube also contains a phosphor powder, coated along the inside of the glass. The tube has two electrodes, one at each end, which are wired to an electrical circuit. hop-louse
