A tube light, also known as a fluorescent tube, is a type of lighting fixture that consists of a long, tubular bulb filled with gas and coated with phosphors. When electricity is passed through the gas inside the tube, it produces ultraviolet radiation that causes the phosphors to glow and emit visible light.
One of the main advantages of tube lights is their energy efficiency. They use less energy than traditional incandescent bulbs and can last up to 10 times longer. They also emit less heat, making them a more comfortable option in warm environments.
Tube lights require a fixture to hold the bulb and provide the necessary electrical connections. The fixture may also include a reflector to help direct the light and increase its efficiency. Some tube light fixtures may be equipped with additional features such as a diffuser or lens to help soften the light and reduce glare.
