Hey chuckh, one last question..... lol i feel like a super noob... anyways, I finally found a seller that has some Catz "galaxy white" 4300k HB5 (9007) bulbs... still haven't bought them yet, but had to ask you this.. Since they are burning at 4300k, there shouldn't be any yellow present at all right? Looking at the kelvin temp. chart, there shouldn't be, but than again, it shows 4000k being pure white as well.... lol so what do you think? 4300k sounds just about white right? I mean Catz are a good brand i heard, ppl state that its up along side with piaa. If you want, give me your email addy and i'll send you some pics of the Catz bulbs, so you get an idea what the coating looks like. Thanks again in advance!
