I'm using this to drive a single high-power LED lamp (perhaps 10W) and it's working fine: nice uniform brightness and it runs very cool. It took me a while to dial in the appropriate current limit (those aren't 10-turn pots; they're like 100-turn!) but once I was able to do that, it worked like a charm. The LED colors and meanings on the product page aren't quite right (some are reversed; "yellow" lights are actually red, etc.) but this isn't a show-stopper.
