CFL lamps, also known as compact fluorescent lamps, are a type of fluorescent lamp designed to fit into standard light sockets as a direct replacement for incandescent bulbs. They work on the same principle as traditional fluorescent tubes, utilizing an electric current that excites mercury vapor to produce ultraviolet (UV) light. This UV light then strikes a phosphor coating on the inside of the lamp's glass tubes, causing it to emit visible light.

The primary advantage of CFLs over incandescent bulbs is their energy efficiency. They consume significantly less electricity to produce the same amount of light, leading to lower energy bills and reduced carbon emissions. CFLs also have a much longer lifespan, typically lasting 6,000 to 15,000 hours compared to the 1,000-hour average of incandescent bulbs. This longevity reduces the frequency of replacements.

However, CFLs do have some drawbacks. They contain a small amount of mercury, which requires careful disposal to prevent environmental contamination. Some people also report a slight delay in reaching full brightness when turning them on, and the color rendering quality can vary depending on the phosphor used. While early CFLs were criticized for their light quality, modern versions offer a wider range of color temperatures and improved color rendering. The production and widespread adoption of CFLs have been a significant step in improving lighting energy efficiency.
