Im getting an Hid kit tomorrowish and am tossed between the 8500k kit for 179.99 or the 6500k kit for 199.99. Which would give me the most usable light out put?

 

as close to 4300k as possible

 

I run a 6K or 8K on my box depending on the day, and when you have one of each in you can tell that the 8000 is a softer light and has a little bit of blue but not overpowering on the color. The 6000 is straight white and does give more output both provide plenty of useable light.

 

 

5000k

 

i would say 6500k if you like crystal purple and 8500k if you like crystal blue--more like blue blue.
