This is true, 3000k and 4300k refer to the kelvin rates. But in terms of internal temperature, I'm talking about the differences between the gases that are filled inside teh bulb. Stock bulbs run off halogen gas filled in the bulb, and when it gets ignited it illuminates. HIDs are filled with xenon gas. Because of the element difference, xenon headlights illuminate a lot brighter. I could google search into the chemistry and physics, but bottom line is if you place your hand on headlights with halogens, it'll probably feel hotter than with the xenons.
