Fluorescent Lamp Tubes

Fluorescent Lamp Tubes

Fluorescent lamp tubes are a type of electric lamp that produces visible light by the excitation of a gas or vapor, which then emits ultraviolet radiation. The ultraviolet radiation is converted into visible light by a phosphorescent coating on the inside of the tube. The tube is filled with a low-pressure gas, usually argon, and a small amount of mercury vapor. When an electric current is passed through the gas, it ionizes the gas, causing the mercury vapor to emit ultraviolet radiation. This radiation then excites the phosphorescent coating, which emits visible light. Fluorescent lamp tubes are commonly used in commercial and residential lighting applications due to their energy efficiency and long lifespan. They are available in a variety of sizes and shapes, ranging from small tubes used in household fixtures to large tubes used in commercial and industrial settings. The most common types of fluorescent lamp tubes are T8 and T12 tubes, which refer to their diameter in eighths of an inch. One of the main advantages of fluorescent lamp tubes is their energy efficiency. They consume less energy than traditional incandescent bulbs and can last up to 10 times longer. This makes them a popular choice for businesses and homeowners looking to save money on their energy bills. Additionally, fluorescent lamp tubes produce less heat than incandescent bulbs, which can help reduce cooling costs in warmer climates. Despite their many advantages, fluorescent lamp tubes do have some drawbacks. They contain small amounts of mercury, which can be harmful to the environment if not disposed of properly. Additionally, they can produce a flicker or hum, which can be annoying to some people.
