I think I came up with a new and relatively easy way to provide good heat sinking for the MaxFlex circuit board. I've seen some very tidy solutions where the board is connected to the underside of the heatsink, but I would rather not connect the only two hot things in the light.
So for my "SinkaFlex", all you need is a 35¢ copper coupler for 3/4" diameter copper tubing. A little filing here and there, some sanding, a quick bend, some Arctic Silver, and you're ready roll. By cutting the coupler open and expanding the diameter a bit, you can get it to spring into a nice tight fit inside the body and still take it out if required. The copper itself is not too thick, but excessive mass only helps you in dynamic conditions. Surface area is the name of the game for steady-state, and this one has plenty, I hope...
Thanks for looking!
