No idea, just stumbled across it searching for cheap led lighting.
I use 2 cheap par38 (18x1w) over a 60*30*36cm tank (60p) with good results and a diy 150w led multi chip over my 90*45*45 tank, so that ossie ebay-store light should in theory be good stuff. Keep in mind that it is fan cooled, so could be noisy.
Link to my diy monster light. I run it at about 50% and itīs still overkill for low tech: https://www.plantedtank.net/forums/sh...=418946&page=3
