Fénycsövekkel, or fluorescent tubes, are a type of gas-discharge lamp that uses fluorescence to produce visible light. Inside the tube, an electric current passes through mercury vapor, which emits ultraviolet (UV) radiation. This UV radiation then strikes a phosphor coating on the inside of the tube, causing the coating to glow and emit visible light. Fluorescent tubes are known for their energy efficiency compared to incandescent bulbs and produce less heat.

The basic components of a fluorescent tube include a glass envelope, electrodes at each end, and a filling of mercury vapor and an inert gas like argon. A ballast is also required to regulate the current flowing through the tube and to provide the initial high voltage needed to start the discharge. Early fluorescent lamps used magnetic ballasts, while modern versions often employ electronic ballasts, which are more energy-efficient and offer features like dimming.

Fluorescent lighting has been widely used in both residential and commercial settings due to its longevity and lower operating costs. However, concerns exist regarding the disposal of fluorescent tubes, as they contain small amounts of mercury, which is a hazardous substance. Proper recycling procedures are essential to mitigate environmental impact. While still prevalent, fluorescent lighting is gradually being replaced by even more energy-efficient technologies like LED lighting.
