Fluorescent lights

Fluorescent lights

A fluorescent bulb or tube uses the flow of electricity to excite mercury vapour in an inert gas (argon or neon), which creates invisible ultraviolet light. A coating of phosphor on the inside of the glass then converts this into visible light - a process known as fluorescence. They have higher energy efficiency and longer life than traditional incandescent bulbs. See also CFLs/low-energy lightbulbs.
