I found a lux meter app for my phone and was very curious to see the lux reading under my Atlantik lights at 100% intensity.At the water surface(so scared I was going to drop the phone in the tank!) I measured 57000 and change under the left and right v1 units and 46000 and change under the center v2.1b unit. Interestingly at least for me that coincides with slower coral growth in the center of the tank. Coral color appears equal to my eyes. Hmm what does the sunlight outside measure? Right now, almost 95000 lux. I realize these are general #'s and different phones may give different results. That said, try installing a lux meter app and see what you get under your lights.I'd be curious to read your results.
