8500K HID Lights
I finally got around to installing my new 8500K HID bulbs. I already had the stock HID, so all i had to do was replace the bulbs. (D2S)

I heard the blue wear's out your eye's at night. I upgraded to 6000k's and I love 'em. They're bright white with a alot of purple. Yours look real cool tho!!! Maybe I should get those???

I have to differ, i think that the blue lights are much easier on my eyes. I have had passangers say the same. also, these lights are not as noticeable as the 6500's because they have no purple in them. I've seen 6-7k lights and they really catch your eye, these just look like a bmw's blue flicker, continuously.

This is quoted from the above site:
"Everything on the road appears blue. After extended use of these 8000K lights (road trips), your eyes will fatigue."
MISCONCEPTIONS
There are many companies and private merchants out there that will advertise 7000K, 8000K, and even 12000K HID kits. Most of these vendors lurk around on ebay, online car forums, websites, and ricer accessory shops. 100% of the people that buy these kits do so because they are uninformed, uneducated, or misguided in the field of lighting, and will buy these junk kits thinking three things: that these bulbs are brighter, that these bulbs should cost more money, and/or that they will perform better. All three statements are completely false. Perhaps this misconception and frenzy for purple lights originates from BMW and Audi's infamous Hella projector HIDs.
So allow me to explain the real truth of the matter... Philips is the number one manufacturer of HID bulbs. The Philips OEM D2S bulb is rated at 4100K at 12.8 volts and produces 3200 lumens of light. The Philips Ultinon D2S is 5800K at 12.8 volts and produces 2400 lumens of light. As you can see, with all other factors remaining constant, the brightness of an HID bulb declines the higher up the color index you go. Vision, a Korean bulb manufacturer, makes an 8000K bulb, which they used to advertise on Acura-Forums as 2000 lumens bright. This is barely a marked improvement over halogens, and will produce more glare and eye fatigue than it is beneficial. 4100K has been proven through tireless independent research by the Germans, Japanese, and Americans to be the most functional, truest white and thus the brightest possible color temperature (ceteris paribus).
Every car manufacturer in the world (including BMW and Audi) uses none other than a standard 4100K gas-discharge bulb. No exceptions. The reason being is that 4100K is daylight white in color and produces the same color visible light as direct sunlight. This is least fatiguing functional color on the eyes and produces the most comfortable contrast on the road.
Dont get me wrong dude I love the way your lights look, but there are the facts.

The Professor
The Kelvin scale of colour temperature does have to do with thermal Temp.
It is dervied by the system of: seeing what colour a small black cube of metal will glow when it gets such and such hot.
Not too suprising, that it would need to be 9000K to glow blue!

there is about 15%-20% less light out put. Also, some things glow blue/white. for example, dirt on the side of the road will kinda flicker....other things will reflect a lot of light back. kinda cool if you ask me. about the fatigue, that worries me 
but i haven't had any problems
