Hello, Weezard! Pleased to meet you, sir I've been reading alot about LEDs in these past few months and your contribution to the area has been very helpful! :thumbsup::thumbsup:

Now, as I said earlier, I would like to make two lamps for ratio-control, so I'm glad to hear you think it should work without adding more heatsink (I'm assuming that's what you meant). The rig was just put loosely together to get the pics so disassembly will not be needed. I wasn't really sure how I would get the joints watertight, but my default plan was to use some kind of glue or sealant. I haven't heard about the "voltaic joint" phenomenon, and although the glue might have prevented it, I will definitely be looking into using the kind of tape you described. It might be a good thing to have a non-permanent assembly for later, if I can avoid the glue alltogether!

As for safety, I'll try to find such a switch as you described there, but could I also add a fuse? If there is a leak somewhere and it shorts the circuit, could I save some expensive LEDs by adding a fuse to the beginning of the circuit and stopping the floodwave of current before it reaches the LEDs, or is that not how it works? (Guess the best thing would be to make the rig water-tight from the get-go, right?)

Well, thanks for tuning in!
