Yup, what he said. The temp of the lamp is personal preference as we have rehashed that topic in another thread.
It has been a consensus that the 4300K is a very appropriate color for use on snow. In this case, a larger number does not represent better. Please keep in mind, this is very relative to each and every owner, and I'm sure we will have some debate in this thread as well. But without a special request, many of these dealers will provide you a 4300K lamp and anything else optional.
I as well have installed a Sledstart kit and two of Rocks kits. (3 sleds, 2 Apex and 1 Phazer) Cake to install and you will spend more time buring wires and zip-tying ballasts to clean it up.
Good luck, If you are unsure, get a good return policy.
