Well, finally got some copper heatsink slugs from a friend (with access to a machine shop). Here's some pics of my mod to a cheap Target torch.
Next pic shows the SE epoxied (thermal stuff) to the copper slug. The circuit board is my own current regulator driver PCB. It's a step down converter with current regulations. Works down to about 4V and then goes out of current regulation. The torch runs on 4AA NiMH batteries.
Next pic shows the installed SE in the torch head
This pic has the SE beam on the left and a Star/O on the right.
cheers,
george.
