Fluorescent tubes are a type of electric lighting that uses ultraviolet light to excite a phosphor coating on the inside of the tube, which then emits visible light. They are commonly used in commercial and industrial settings due to their high efficiency and long lifespan.
When purchasing fluorescent tubes, there are several factors to consider, including the size, wattage, color temperature, and type of ballast. The size of the tube will determine the amount of light it produces, while the wattage will determine the amount of energy it consumes. The color temperature of the tube will affect the appearance of the light, with warmer temperatures producing a more yellow light and cooler temperatures producing a more blue light. Finally, the type of ballast will determine how the tube is powered.
