Default 8000K vs. 10000k HID Kit

What do you guys think would be better, a 8000K or a 10000k HID kit?

4300K. anything higher is too ricey IMO. If you must, 8000K would look much better.

I would go 5000K, no joke.

I went from stock HID's to 8000K and Actually lost visibility despite upgrading from 35W to 55W ballasts. Yes, it's pretty blue but it's not as bright and it's more tiring on your eyes. There is a reason why OEM systems are 4000K-5000K. A lot of people don't know this, but increasing the color temperature decreases the light output significantly. depending on the brand, 8000K loses 30%-40% output vs the OEM bulbs.
I'm going back to 5000K this week.

*edit* ^ damn I type sloooow...

Fun fact:

The higher the number, the worse the visibility.

Purple light doesnt reflect much.

-The proper torque for just about any bolt: Tighten until it snaps off, then back off half a turn
-Your from the "measure-twice/cut-wrong" school of carpentry, huh?

5500K is about as close to pure white as you can get IIRC

I appreciate all the replies and i guess it would make sense. I guess i will keep it at a lower number.

The temperature is related to the peak wavelength (color) of the light spectrum emitted by the bulbs. Higher temps produce shorter frequencies like blue and violet, and produce light outside of the visible range (visible = 380-750nm).

If you put the same amount of energy/time (power) into different temp bulbs with the same efficiency you should get the same amount of energy (light) out of it. The scatteriing or reflection of light depends on many factors such as angle and material properties. For instance, the probability for the atmosphere to scatter light depends inversely on the fifth power of the wavelength. Therefore blue and violet are strongly scattered. The human eye is much more sensitive to blue light and therefore the sky appears blue.
