You WANT your light to get hot, your going to kill your Malkoff if you don't dissipate the heat. it might not show right away but your slowly cooking the led and it wont last very long at all.

The aluminum foil is going to help conduction of heat from the module to the head/body. I use foil for all of my LED drop-ins for Surefire bodies. Use of foil will result in slower drop off in output due to heat. It is measurable and I have compared runtimes using Malkoff M30 with and without foil using bounce with lightmeter. Not sure why the poster said he did not feel any heat pulling 2+ amps, using the Malkoff P7.
