\nCFL is a type of fluorescent lamp designed to replace incandescent lamps.
\n<\/section>\n
\nThe acronym CFL stands for Compact Fluorescent Lamp. These lamps are designed to be smaller and more energy-efficient than traditional linear fluorescent lamps, allowing them to fit into the same fixtures as incandescent bulbs.
\n<\/section>\n
\nCFLs work by passing an electric current through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light, which excites a fluorescent coating on the inside of the tube, causing it to emit visible light. They use significantly less energy and last much longer than incandescent bulbs, although they contain mercury and require special disposal.
