Mike I wasn't here whenever they were installed but my wife say's these are 'cool white', we did have two cabinets in the kitchen that had brighter white lights installed mistakenly and we didn't like the color, they were a very artificial whiter light and they just didn't look natural.
I'm a bit confused Rick... 4300K is pure, white light. The terms "warm" and "cool" are relative the light spectrum. Warm is lower on the scale, given the light a yellow tint. When you move above 4300K, it is considered cool, with a tint of blue. For example, if you've ever been blinded by one of those dumbasses that swap out their headlights with irritating blue and purple HID headlights, those would be considered "cool white". Yellow fog lights on the other hand would be considered "warm white". 12V halogens are typically very close to 4300K.
