“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.”
Seeing Gakona exhibition in Paris gave me a special attention to observe situations of energy tension . The exhibition was more focused in the myth that population creates behind phenomena’s or the use of electrics by Man kind . But those Myths grow up for respect to Nature uncontrolled power.
