Fluorescent tube also known as fluorescent lamp, is a low-pressure mercury vapor gas-discharge tube that converts fluorescence into visible light. Fluorescent tube lamp have the advantage of being much more energy efficient than incandescent lamps. They are a relatively low-cost and long-lasting type of lighting and are used in a variety of residential and commercial applications.

The fluorescent lamp is easy to attract dust when it is hot. When it is ready to clean, turn off the power supply, and then try to let the indoor air circulate. Wipe the lamp tube gently with a twisted dry rag dipped with a little detergent, and then use a clean dry cloth to clean the detergent.
