Thank you to everyone for the interesting reads. I had no idea that LEDs draw as much as has been stated here and the info. on lights with cooling systems is interesting too.

I'm figuring retrofit kits in the future will look like the KIA's headlights, 4 independently focused beams that can basically be glued into any housing you can think of. Thus (hopefully) negating the need for cooling fans. Those CREEs shown above need to run much brighter because they had to be designed to work with a reflector that was never meant for LEDs. I'm assuming (and its a big assumption) that cooling fans would not be necessary on the KIA because the reflector is designed to work with the LED. New LED flashlights are really bright with a beautiful beam pattern and if they don't need a cooling fan, why would ones designed for use as a headlight need them? Lets me honest, the reflector is just as, if not more, important than the source of light.
