I don’t want to push you into doing this if nobody else is interested in them!
I’d buy a dozen, couldn’t use more soon. See if anyone else is interested to make it worth doing?
I’d wish for pills with solid back planes to mount the LED on so I could use the square 10mm Luxeon Rebels.
But if they have ledges I can stuff in a copper or aluminum disk with some thermal epoxy, I’ve done that with ok success before (and just drilled my own holes for wires)
But before you spend any time and effort on this — I’m just some guy, I would not be making these up to resell, but to give as gifts
I’d be putting in BLF 15mm SK68 drivers if I didn’t keep the originals, and “anything has to be better” LEDs.
One annoyance with improving SK68s is that it’s hard to solder drivers to pills — I just dropped one and had the driver edge solder crack off the aluminum pill.
No problem for me, but a fairly common failure when they’ve been given as gifts so I end up redoing that solder bridge.
I don’t know a simple good way around that problem of grounding the driver to the pill that’s idiot proof against dropping them.
