Characteristics:
    1. Uni-form 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 lumen 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 around the arc tube, explode proof, ultraviolet radiantion shield; suit for the Open Rated or Enclosed Rated  fixtures. UV-stop.

Application: public lighting, street, road, industry, commerical, building flood lighting, sports gym, ceiling lighting, especially the occassions which require high illuminance and produce high quality products, such as the steel factory etc.
