OEM lasers in 26.5mm modules?

Something like this is what you ant copper tape for non solder applications.

Thing is, if the heatsink is 26mm in diameter anyway then that's already quite a large mass. Using the copper tape will mean there is some dissipation to the host (even if not a huge amount) so it'd, surely, just mean slightly longer cooldown times.

Don't discount the p60 drop-in yet. Remember, p60 is for a portable light. You want infinite duty cycle? get a labby.

I've never used the copper tape, but I've used foil with noticeable results, even with multiple layers (and hence, multiple air-metal junctions), on some LED drop-ins. Before and after was noticeable with my hands. (LED drop-in was a k-bin MC-E)

Now, keep in mind, these are LEDs. I haven't tried it with my laser because:
1: the heatsink doesn't get hot.
2: I had it made specifically for the L2, not the surefire or ____fire.

I think as far as filling the gap goes, copper foil > aluminum foil > copper tape.

I should add that right now, my MC-E drop-in is in the ultrafire C1 with some Al foil, and you can barely pull that drop-in out. You have to go at it by prying it up bit by bit. Hopefully that's enough metal-on-metal contact to have better thermal conductivity than when it was just floating around in the drop-in pocket.
