I have this in my build thread too, but thought might as well put it in a more visible spot for anyone that might be curious. There are 5 units over my 48" 120. I would probably not have that many if I had not won 1, but I am really happy with the setup of having 5, there is a great amount of overlap so areas that would be totally shaded at least get some light.
The light levels are very even over the entire surface, spots where you see higher numbers like on the right rear are because the ceramic rock there is tall but hard to tell from the picture. The coral in that spot are under only 4" of water.
