I forgot to say in my previous post that the watts at the wall is about 15% more than the watts at the board, which is the same as the Meanwell drivers. As for the output, I feel pretty confident to say it's the equivalent lux to the ChilLed puck which does use Samsung diodes. With white light the brightness as seen is good enough.
In a nutshell, the quality of he components may be a bit less than QB's with Meanwells, but you'd expect that, they've cut the price in half compared to what I'd normally have to pay in Australia. The efficiency is the same and a photon is a photon, the plant doesn't care. Anyway, I'll be starting a grow with this tomorrow by the look of it as my Think Big looks like it will be up tomorrow. So I'll be taking this all the way through under this light.
