There are no instructions or warnings on how to use this, so you are on your own. The input side is labeled "i" and "i" on the sides of the case, so apparently it is agnostic as to which one is power and which one is common. When I bench tested it, it worked, but after I installed it, it failed. Its only then that I realized that the wires are probably color coded to the European union convention - brown for positive, blue for neutral, and white/green for ground - but who knows? Still, even if I reverse wired it, it should have been robust enough to handle the error. Stay away from this one. Get one with basic buck converter functionality built in (like short circuit or reverse wiring protection).

All aluminium constant current supply to replace one that failed in one of my 50w spotlights. Easy replacement that worked good.
