Very nice. I need to do mine cause you can't see **** at night in my a4.

 

Looks good man. I bumped up to 6000k from the stock 4300k xenons and I'm pretty pleased with the color. 5000k would be brighter though right?

 

Yes. It's more white than the 6k. The 4300-4500 are basically white, lower gets yellow and higher turn blue'er then purple. Whiter the brighter

 

Ya I got 6000k, 4300k is white which gives the most visibility. Nothing like looking at xeonon gas electrons change energy levels creating photons of light!

 

Thanks. Yeah, it's a huge improvement over halogen bulbs. I think this color temperature provides the most light too. I used to run 10,000k a while back and it would just make signs and reflectors on the road glow.

 

4300K is peak output in terms of luminous intensity (the most usable light). All OEM applications run 4300K. As you move higher in the color temperature range the amount of usable light drops off drastically. If you move high enough, you'll end up with less light than the Halogens originally made. There is a false sense of intensity as the light shifts to the UV end of the spectrum.

People often use high color temp bulbs to gain that color flicker effect of the projector lens. The cause of which is simply the prismatic effect of the lens separating the colors of the light into a band at the top of the cutoff.

If you're interested improving the performance of your headlights, you shouldn't venture above 5000K.

 

I always wondered what setup some cars have with projectors when the color changes, seeing the car at different angles. For example, blue head on and white from the side. Is that what you're talking about?

 

I want to see some 3000k in the fogs. I still have to get some depots after i pay my taxes

 

Depo e-codes are on my list for this summer as well. I'm currently running "3000k look" H7 bulbs in my fogs and they look decent. Not as bright as projectors would be though
