Here is my 120 gallon mixed reef with one cozumel hamiton pendant 13" off the water. Its lighting an impressive 4x2' spread, I only wish I had a par meter might be the perfect light for a 4' mixed reef, nice par in the middle two feet with lower on the edges for lps and softies. I bought two pendants but I'm gonna see how one does for awhile before hanging the second. iPhone photo doesn't do the color justice
