Gas discharge lamps have the following characteristics: 1 The radiation spectrum is selective. By selecting an appropriate luminescent material, the radiation spectrum can be concentrated at the desired wavelength, or several luminescent materials can be used simultaneously to obtain the best combined spectrum. 2 with high efficiency, they can convert 25-30% of input energy into light output. 3 long life. The service life is up to 10,000 hours or more than 20,000 hours. 4 The light output maintains good characteristics and can provide 60-80% of initial light output at the end of life.
