The 8000K's and up put stress on your eyes. That's what I had on the setup I posted pictures of and it hurt my eyes. The way I could tell is at night I would turn off the headlights and leave my 3000K fogs on. When I did that, it felt as though I had relieved stress on my eyes. I now have 4300's and it is way better.audtatious wrote:I would suggest nothing over 6000k as the drop in lumens goes up exponentially.
