"Sellers that claim the higher the Kelvin rating the brighter the light. 4300K is actually the WHITEST part of the lighting spectrum. 6000K and upwards still provides triple the output and visibility as conventional halogen bulbs, but with a bluish hue."

While this statement is true at face value (the higher K lights do actually still provide 3X the lumens) it DOES NOT provide triple the usable light. Higher K you go, the less usable light you have and the worse the lights will do at night. Just keep it in mind....
