When you get up to 8K you are going for color but the output is still vastly superior to OEM Halogen. 10K, 12K and getting up to 30K. The deep blue, purple and pink lights you do notice a lose in output. You also will start to run into eye fatique on long night drivers with the high Kelvin temps.
Epic post!

LOL@Frog - no shit man, haha.

I have 4.3k headlights and 55W 6K fogs.
If I had to do it again I'd go 3k, but I didn't know they existed back then (maybe they didn't) lol.
