Finally did it! I'm really crazy about these triples.
My ARC's were sitting around, outcast and lonely with their poor dim Luxeons and underdriven electronics. Glad I never sold 'em now!
I'm sorry I didn't take in-progress photos but I was excited about this one!
I used the original aluminum heatsink, cut the electronics off the one side and Arctic Alumina'ed (AA) a Shiningbeam driver to it after I soldered the power wiring to the driver. Picked up power at the points on the original circuit flex where it bends around to the front side of the heatsink.
Used a sanded down copper penny for the LED board... I wired LED + and - to the driver first, drilled a hole in the center of the penny to get the wiring through and AA'd it to the front side of the driver.
AA'd the triple to the penny, wired it (parallel obviously) and checked it for operation.
OK, what can I use to enclose the sandwich in?? No proper fitting sleeve at the hardware store and no machine shop. I had some aluminum strips that I had cut from a generic supermarket baking pan that I used for P60 dropin shimming, so I cut it to size, wrapped it around the sandwich and AA'd it to everything. So now you're looking at a little pill with the triple on the business end and the original ARC battery contact on the other. Not polished and pretty, but machine shops are for the rich...
Sanded down the edges of an extra AR lens I had so it'd fit in the host, added a glow ring, put heatsink compound on the pill and tightened it in-carefully-with the original ARC threaded ring.
Done! Beautiful flood, gets warm immediately so my half-arsed heatsinking works, and it looks great! On high it's for the wow factor, more practical to use it on medium. Carlco medium frosted optic, 5000K XPG's, and the belt clip is from an Energizer 1W from Target. "Tactical" O-rings added for my fat fingers.
Enjoy!
