I want to mod Technisub VEGA 2 with three XML-U2's. I wondered to use Intel 775 CPU heatsink. The question is, whether it is possible to cool those leds driven at 2.5A each with this heatsink in a full plastic body? Unfortunately it is impossible to transfer the heat to water. The heatsink (any) would have to absorb all the heat produced in about half an hour.
Is there any other way how to mod this flashlight with these leds?
