Xenon Blub Upgrade?
 

I am looking into upgrading my stock xenon blub with a set of 10000K. I was just wondering what is the stock temp. 4300K?

Don't really think that is an "upgrade" as far as light output. 10,000K will put out less light (lumens) than the stock bulbs. It will give you a different color that's it.

Yes Denalio,

I mean I want to upgrade the color or the xenon.

10,000k is so purple that my flashlight will put out more light than your xenon. Even 8000k is pushing toward the dark blue/purple spectrum. To answer your question...yes, the stock bulb is 4300k

Well here are my 2 cents, i got a e53 and i just installed 8000k and sure there is a difference but with xenons the difference for me is nil and i dont wear glassess, lol. Seriously tho, i would get them if you like the colour look, but the difference ppl are talkin about is what they have read from hid kits for non-projector lights, i think they are fine, its still illuminates the road enough and the projectors give it less glare normally seen in halogen upgraded lights! I say go for it, dont push over 8000k, then you be lookin to cook some uncle bens, but 8000k or evn 6000k makes a nice difference.
