1). The internal and external xenon bulb is Phillip’s, others may use GE or made in China
2) .The Metal Halide made in USA , others may made in china .
3). The Mercury’s Purity of xenon bulb is 99.999999%, others is 99.9999%,The purity is more, protect the electrode is better
4). Imported the newest product line from Kore, most of are made by machine
5). The ability of Anti-UV is best as choose the Silica Crystal Glass tube
6). Permeability is better
7). The xenon gas imported from Germany , the purity is higher
8). Atmospheric pressure of internal bulb is higher , Keep up to 6 pa ,that can protect the electrode, enlonger the life of xenon bulb
9). Every ballast suit for every xenon bulb, down the defect rate.
10).The international xenon bulb voltage is 85±17V,Ours are 85±10V,suit for the specification
11). Special for Phillip’s, The internal Xenon bulb’s Diameter is 9.0~9.1mm.
