energiasäästulamp

Energiasäästulamp, also known as a compact fluorescent lamp (CFL), is a type of electric light bulb that uses significantly less energy than incandescent bulbs. CFLs work by passing an electric current through a tube containing argon and a small amount of mercury vapor. This generates ultraviolet (UV) light, which then excites a fluorescent coating on the inside of the tube, causing it to emit visible light. Compared to traditional incandescent bulbs that produce light by heating a filament until it glows, CFLs are much more efficient, converting a larger percentage of electrical energy into light rather than heat. This increased efficiency leads to substantial energy savings over the lifespan of the bulb, making them a more environmentally friendly choice. They also tend to last much longer than incandescent bulbs, reducing the frequency of replacements. However, CFLs contain a small amount of mercury, which requires careful disposal to prevent environmental contamination. Modern CFLs are designed to minimize mercury content and have improved starting times and color rendering compared to earlier models. They are available in a variety of shapes and sizes to fit standard light fixtures.
