Yeah the problem is the light makes so much heat(the boost as well) that i cant dump it into the air with high enough efficiency. The bodys going to be aluminium and the pcb copper.
Hm, that reminds me! If you're designing your own PCB, some manufacturers will make the PCB out of aluminum for you instead of FR4. This is commonly used for high-intensity LED lights to help keep them cool.
Here's some random info about them so you can see what I mean:

An alternative would be copper-clad polyimide adhered to the body. That also has better thermal properties than FR4.
I was already planning to use a copper core pcb. This is pretty common among insanely powerfull lights. The flashlight community has some great examples. But most of these lights use resistor based voltage regulators which waste a lot of energy in the form of heat so im trying to improve on the traditional design.
That sounds even better!
