What is cfl meaning?

CFL stands for Compact Fluorescent Lamp. It is a type of energy-saving light bulb that uses less energy than traditional incandescent bulbs and lasts longer. CFLs are typically spiral or tubular in shape and contain a small amount of mercury vapor that produces UV light when an electrical current is passed through it. This UV light is then absorbed by a phosphor coating inside the bulb, which causes it to emit visible light. CFLs are popular because they can save up to 75% on energy costs and last up to 10 times longer than traditional incandescent bulbs. However, they do require special handling and disposal due to the small amount of mercury they contain.
