CFL bulbs, or compact fluorescent bulbs, are a type of energy-efficient light bulb that uses less energy than traditional incandescent bulbs to produce the same amount of light. They work by passing an electric current through a gas-filled tube, which produces ultraviolet light that is then converted into visible light by a phosphor coating on the inside of the tube.
CFL bulbs have a longer lifespan than incandescent bulbs, typically lasting up to 10 times longer, and use up to 75% less energy. They are also available in a range of color temperatures and styles, making them a versatile option for a variety of lighting needs.
However, CFL bulbs also have some drawbacks. They can take a few moments to warm up and reach full brightness, and they contain a small amount of mercury, which makes them more difficult to dispose of than traditional incandescent bulbs. Additionally, CFL bulbs may not be compatible with all types of dimmer switches.
Despite these limitations, CFL bulbs remain a popular choice for energy-efficient lighting, especially in commercial and industrial settings. In some countries, regulations have been implemented to phase out the production and sale of incandescent bulbs in favor of more energy-efficient options like CFLs.
