I got 6000k, most OEMs use either 4300 or 6000. Light output is excellent with the 35w, that is standard for HIDs as far as I can tell. GM OEM HID bulbs are 35w as well. I just ordered mine and will post some pics up when they are installed next week some time. Hope that helps!Looks good to me, I would rather buy them from a company then E-bay anyway becouse of the warranty. What color did you get, I think I will get the 1000k. How is the light output with the 35w?
