Energiasäästölamput

Energiasäästölamput, also known as energy-saving lamps, are a type of lighting technology designed to consume less electricity than traditional incandescent bulbs while providing a similar level of light output. The most common type of energy-saving lamp is the compact fluorescent lamp (CFL). CFLs work by passing an electric current through a tube containing argon and a small amount of mercury vapor. This process excites the mercury vapor, which then emits ultraviolet (UV) light. The inside of the tube is coated with a phosphor material that fluoresces when exposed to UV light, producing visible light.

Compared to incandescent bulbs, CFLs use significantly less energy, typically around 75% less, and have a much longer lifespan, often lasting 8 to 15 times longer. This efficiency translates to lower electricity bills and reduced environmental impact due to decreased energy consumption and fewer lamp replacements. However, CFLs contain a small amount of mercury, which requires careful disposal to prevent environmental contamination. Newer technologies, such as LED (Light Emitting Diode) lamps, are increasingly replacing CFLs as they offer even greater energy efficiency, longer lifespans, and do not contain mercury, making them a more environmentally friendly option. The term "energiasäästölamput" can broadly encompass both CFLs and LED lamps due to their shared goal of energy conservation.
