Most also asked me,Is it very bright When the color temprature up to 8000k or 10000k ? Here, I'll explain color temperature (K number) and brightness of relationships on HID Headlights:

1、More highr aout the K number, More brightness, actually this is a wrong understanding, 4200 K is a demarcation line, The spectrum can produce maximum brightness of K number, downwards, light color is yellow, Up to 3000 K , "golden eye", the upgrade, light color is blue, and even purple with rage. Finally become a "color lamp" , What's more ,lack of brightness.

 

This is the physical spectroscopy law in HID Headlights : color temperature inversely proportional and brightness, the higher of color temperature,the lower of the brightness
