Today I had to change measure PAR levels and spectrum distribution of DIY led I build for the pico reef. It seems that there is quite much power under the fixture. Of course there is massive falloff to left and right side. I think the fixture can handle some SPS corals if positioned correctly. I used Seneye device to run measurements and it was taken without water on the tank (so there is some reduction of PAR levels when water is in the tank).
