So I got these new cheap 8000K HID d2s bulbs from ebay and pit them against philips ultinon 6000k
the 1st and 2nd pictures show the driver side with 8000k vs 6000k on passenger. as you can see, when you look straight at the source, it isnt quite blue, but the blue really shows on the wall. Im surprised that the output of the 8000k bulb is pretty good. not bad for $50 bulbs.
