Here is a link to my full review with pics, par readings etc. http://www.3reef.com/forums/led-aquarium-lighting/reefbreeders-120watt-dimmable-fixture-review-pics-par-numbers-137792.html I had to turn down the white's and adjust the photoperiod because my tri-colored acro was bleaching and I am not able to move it down in my tank without doing harm to it as it has attached itself to the rock that it is on. So far so good, I like the color and the ability to control the 2 channels. I am using a marineland submersable LED nightlight that I won as a nightlight for now. Also, for whatever reason, my darth maul colony died, all my other coral's look great.
