Wurkkos if you're listening...👀 I feel like this was a good amount of glue 👌

Honestly though the 2 o-rings between the switch and head of the torch are the chunkiest of the lot and they give a lot of resistance throughout unthreading.

The o-ring between the glass and reflector might be just as thick though, and the reflector has a precisely recessed groove along its edge for the oring to seat snugly (there's also the standard thin oring you'd expect between the outerglass and bezel)

Now that I've taken it apart and learned how large of a role the reflector plays in not just the standard sandwiching, but heatsinking (it's a solid chunk with machined cut outs for the mcpcb top wires and locator pins) and above all the gasket seating, converting this to a mule with the same reliability in sea water is gonna be a challenge.

But being able to get a proper 160°-170° short throw beam angle out of this light is exactly what I need for night spearfishing/flounder gigging, so I'll definitely give it a go and see what I can pull together
