That might be THE single dumbest thing I've ever heard...maybe if you installed a 55w bulb on a 35w system it would pop the ballast, but that's why you check the wattage before you buy bulbs. Typically OE systems are 55w in my experience. Thus, you would buy 55w 6000K bulbs. Voltage and resistance don't change, only wattage. That's why you can run a 35w PnP HID kit on the factory 55w halogen system (as I will be doing soon)
See answers in red:
Also, to clarify, the reason that higher color temperatures are a waste is that as color temperature increases, so does the wavelength of the light, resulting in lower output of Lumens. This means the actual light output is decreased and will tend to cast more shadows than light things up. In my experience 4500k - 5000k is the ideal range for a balance of light output and appearance. I also prefer to use 3000k in my foglamps as particularly in winter and wet road conditions, they help illuminate a lot of the stuff you'd normally miss with standard lights.
It should also be noted that wattage is a factor, in that a 55w kit with one step higher color temp will have better output than a 35w kit with a lower temp. For example, a 55w 6000k will have better ouput than a 35w 4500k, etc.

meh...they are chinese parts, so they definitely are cheaper, but I've had DDM's PnP kits (total count of about 6 of them) on multiple different cars over the years and never had so much as a flicker. Even with 100° summers and 5° winters I've yet to have a failure, and that's why I'm going to be getting them again.
