anyone who is considering building a LED fixture should not be unexperienced with electricity in the first place. besides as little as 35Vdc can give you a hell of a jolt, more so if the power supply allows for higher currents, the TR does have short circuit protection which should tell you if something is wrong the first time you plug it in

think about what were doing here. we're soldering a ton of wires to pads on a hunk of aluminum and suspending it over a tank of water... what is safe about this in the first place? as with any DIY involving electricity, this is not for some one who doesn't feel confident working with electricity and there skills to do so.

I am actually testing a couple ways to electrically isolate everything after it is together, for a few reasons. one - so humidity can condensate and make a water drop shorting out a led to the heat sink, two - so you don't bump a bare wire while your working by the light, and 3 - to prevent corrosion of the solder joints from salt creep and humidity. when I find one I am happy with I'll post it, but so far the liquid electrical tape is looking pretty good.
