Advantages: energy saving, fluorescent lamps consume about 60% of the energy can be converted to ultraviolet light, the other energy is converted to heat. The efficiency of converting UV light to visible light is about 40%. So the efficiency of the fluorescent lamp is about 60% × 40% = 24% - about twice the same power tungsten wire lamp.
Disadvantages: will produce light failure, fluorescent color than the incandescent lamp; light flicker phenomenon, have a certain impact on vision; In addition, in the production process and the use of waste after mercury pollution, resulting in environmental pollution.
Scope: factories, offices, schools, supermarkets, hospitals, warehouses and other indoor public space.
