Is 8000K brighter than 6000K ?
The correct answer is no. The Kelvin scale is a measure of the color temperature, not intensity or amount of light. HID setups that produce maximum light output are around 4100-4300K colour temperature, and the higher you go, the less light output. A 12000K HID kit will be dimmer than your stock halogen lights. 4100-4300K kits will have the colour of all the HID lights you see on cars that come equipped with them (like most BMWs, Mercedes-Benz’, and other luxury vehicles). The colour is very white, while light output becomes progressively bluer as colour temperature rises; 6000K is white/blue, 8000K is very blue, and above that you go towards purple. The purple/blueish color you see on OEM HID equipped cars is the light refraction in the projector glass.
