thats exactly what i was thinking.... so its basically a coin toss betweenDepends on what kind of light you want really. The 5000k is more clear like a white light and provides better viewing at night. 8000k is getting into the blues/purples and do not provide very good light at night, mostly for show. 6000k is kind of nice, should be a comfortable medium.
get the Oracle 8000K like me. they are white with a blue hue, in which in my terms is perfect. you can get them from Chad from "Unique Coatings & Automotive Lighting Specialties".
in this pic, my aiming was a bit too high, its adjusted now so it doesnt light up the top of the building.
some kits heat rating is different, you might see a 8000k that seems pure blue and you might see the ones like mine, that are a white/blue.
10k is still much better than any halogen. so your wrong about that. yes they will not put out as many lumens as lower kelvin rated bulbs. but any hid is better than halogens. and no 10k is not beyond the visible spectrum of humans because i had 10k in my 04 gt-s celica and i could see way better than in any previous vehicle id owned with halogens. so if that were true all vehicles sold with halogen headlights would be considered dangerous.i have 6oook with infiniti balsats from a G37 and let me tell ya.....rain shine snow hail whatever...lights and fogs on i can see for almost a mile both vertical and horizontal since i dont have projectors lol the only time i have problems is in sandy areas. other than that its great. its a white color with a hint of blue any rating higher than 6k you will lose visibility in any condition because the light is starting to go lower than the visible spectrum of humans. using a 10k is like using a candle in the dark. 5300-6000k is best.
