Characteristics:
   1. the lastest manufacturing processes for quartz arc tube;
   2. do not need assistant electrode;
   3. working starting with impedance ballast and high pulse ingnitor, it is worthy of the name of "pulse started";
   4. if being used in reasonable circuit, can protect the electrode very well, and extend its service life, which can be up to 20000h;
   5. the arc tube can be lighted at any burning position;
   6. much high lumen efficacy( 100lm/W), and excellent color rendering index( above Ra65);
   7. sending out bright light that makes you feel the real sunshine even indoors.

Applications:  road, street, commercial, industry, building flood lighting,  sport gym and other lighting occassions.
