It depends on what you're going for. If you're interested in that high of temperature range, you will be sacrificing visibility for color output. Those will be either a solid blue, or purplish. I have 6000K, and they're bluish/purple. Don't get me wrong, 8000K will still have more light output than halogens, but the lower the temperature rating, the brighter they'll be. It comes down to what you want.
