Fluorescent Lamps
A Fluorescent Lamp or Fluorescent Tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. Unlike incandescent lamps, fluorescent lamps always require a ballast to regulate the flow of power through the lamp. However, a fluorescent lamp converts electrical power into useful light more efficiently than an incandescent lamp. Lower energy cost typically offsets the higher initial cost of the lamp. While larger fluorescent lamps have been mostly used in large commercial or institutional buildings, the compact fluorescent lamp is now being used as an energy-saving alternative to incandescent lamps in homes.
Fluorescent lamps contain mercury as a vapor and in the solid phase. Mercury vapor from broken tubes can contaminate the immediate area and may affect nearby people. Mercury is easily absorbed into the lungs and brain and is difficult to remove. Mercury is a Neurotoxin.
