[PSUBS-MAILIST] Medical clamps and K Boats

[Alan via Personal_Submersibles]

Thanks Brian.
I will keep posting what I am doing with my new Flip LEDs in case it's of any
interest or you can put me on the right track. I bought the bare emitter, which
requires soldering the wires on to the heat sink. After some futile attempts at soldering
with a 25W gun, China advised me that I needed at least a 120W of heat.
so am ordering some more LEDs pre-soldered. Can't afford the wires falling off when
they heat up.
Cheers Alan

Turned a piece of aluminum bar to sit under the bulb as a heat sink. Also nicely holds the bulb just under the lens. Found an old, cheap Dive Rite canister designed for a regular lead acid battery. Replaced battery with Li Phosphate and that left enough room for a transformer. It worked so well I made one for Harold.
