1, the use of high-quality quartz arc tube, so that the spectral types given a richer, more densely distributed, thus better color rendering. 
 2, in the course of normal lighting, the lamp electrodes for better protection, can make a more lasting lamp life. 
 3, the electrical system is compatible with good features, you can directly replace other high-color rendering of the European standard metal halide lamps. 
 4, high light efficiency and long life, can reduce the use of light engineering, electrical and lighting bulb replacement to reduce the number of times, thus reducing maintenance costs. 
 5, has a special anti-UV glass tube structure, to maximize the prevention of ultraviolet radiation, a higher standard of green products
