48" LED Array - Up and Running...Mostly

[Ron99]

For comparison purposes Eugene at Oceanic Corals tested their 400W MH fixture (in their LED spotlight thread) and says that PAR was 500 at 12" below the water. I had 400 PAR at about that depth with the fixture say 7.5 inches above the water. I'll try to test with the fixture closer to the water at 12" depth and see what I come up with.

But I think my 400PAR as tested so far shows pretty well against the MH.
