Also got this to pair with the 50W led module as those need constant current but not voltage (to avoid burning them out). Build quality seems good and I guess it is waterproof as well (i.e. can be placed outdoors to drive LEDs at yard).

I'm using them with the SKU072299 50W COB LEDs (with big heatsinks of course) and they seem to work very well! Measured output power is fairly near to 50W, so you get what you order.

Doesn't work , Flashes , Goes Off , Goes On . Don't know if it's the LED over heating or what , So I got a special heatsink made of this LED , No help . Banggoods know sells a new 50w driver so I ordered one , got it the other day , hooked it up to the LED that was flashing and going off , works fine . It was this driver . I paid $13.11 for the one that doesn't work , the one that does work was $9.11 go figure .
