I bought 3 mc-e torches from dealextreme and was worried about heat, so based on some reading decided to wrap one of the dropins with heavy aluminum foil from a baking pan last night. I brought all 3 in to work and shot them with our thermal camera to see if it really works, not just by feel.
You can tell the modded one transmits the heat to the full cap much quicker than the other 2 without the aluminum. It was also about 5F hotter when I shut them off.
A free mod (after washing the aluminum pan) that works.
ambient temp on all 3 laying on floor
about 60 seconds in the difference is very noticeable and you can see the middle one was hotter at the end where the reflector contacts the cap
75 seconds after that, you can see it's hotter and more uniform
Here's a second test I did after they had cooled back down, this shot is just 10-15 seconds after turning them on
and just a little bit later with my hand as a reference
