We should add a little note for safety in here: Any of these drivers CAN kill you. If you touch the bare leads with no load, it will put out as much current as it can at the top voltage. THAT CAN KILL YOU!
Of course, you can stop your heart with a single D cell, if you connect it to needles and stick them in both arms. But I’m talking about ordinary skin contact. They probably have a floating output, so you would not be in danger if you touched a single output and a cold water fixture, but I would not count on it. You might want to make sure you are on a ground fault protected circuit to increase safety.
If you touch both leads of a 45 volt or higher COB with one hand you will get a shock, surprising but not too harmful. I wouldn’t try it with both hands or wet fingers. Shocks across your hands go through your heart. Use electrical tape or heat shrink tubing as needed and make sure none of your connections touch the heat sink, etc. Keep you wires tie-strapped to the frame so they are not hanging down. Do not try to use bare stranded wire under a screw terminal. Use a terminal connector or at least tin the wire with a little solder so the strands don’t go astray. Use adequate gauge wire for your current. You can look that up online.
