Characteristics:
    1. single pulse start: it declines the igniting voltage when starting the lamp, avoids lamp nigrescense in early using; reducing light attnuation, extends the lamp service life;
    2. compliance of light&color: the arc tube adapts special oval shape outline design, can bring excellent color and light compliance, achieving the effect of ceramic metal halide lamp;
    3. universal burning position: the arc tube can be lighted at any position, including horizonal burning position and vertical burning position, but the vertical position is better;
     4. no welding-point structure: with no welding-point installation structure, can prevent bracket welding-point from breaking while shaken fiercely, enhanced the lamp stability;
     5. high luminous efficacy: it is 20% higher than the common Metal Halide Lamps;
     6. if used in the reasonable circuit, can protect the electrode very well and extend the lamp service life, which will be up to 20000 hours;
     7. stable and short restarting time: it  takes 50% less time than that of commong lamp to restart.

     8. with quartz inner protection wall, explode-proof, ultraviolet radiation shield; suit for the lighting fixtures which do not have protection glass.
