Fosforrör

Fosforrör, often referred to as fluorescent tubes or fluorescent lamps, are a type of gas-discharge lamp that utilizes fluorescence to produce visible light. Internally, the tube is coated with a phosphor material. An electric current passes through a gas, typically mercury vapor, which emits ultraviolet (UV) light. This UV light then strikes the phosphor coating, causing it to fluoresce and emit visible light. Fosforrör are known for their energy efficiency compared to incandescent bulbs and produce a less harsh light. They come in various lengths and color temperatures, ranging from warm white to cool white and even daylight simulations. Common applications include general lighting in homes, offices, schools, and industrial settings, as well as specialized uses like grow lights for plants. The lifespan of a fosforrör is generally much longer than that of incandescent bulbs, typically ranging from 10,000 to 20,000 hours depending on the type and usage. While energy-efficient, they contain small amounts of mercury, requiring proper disposal to prevent environmental contamination. Modern alternatives like LED tubes are increasingly replacing traditional fosforrör due to even greater energy savings and longer lifespans, along with the absence of mercury.
