Most OEM setups run at 4700 - 5000 deg K. I personally run a set of 6000 deg K, which are very, very white with a little purple band around the edges. If I did it over again I would probably go with 5000 deg K for a little better visibility. Remember, as the color temp goes up the light output goes down.

BTW, the link you posted is the exact set that I have. I have had them on for a little over a year now and have not had any problems with them.
