The Reef Breeders Photon is a wonderful light. Just had a friend purchase one and he is extremely happy with it. That is a lot of light for a 55G.... I would seriously consider either a 75G or 90G for a 4' footprint. It is extremely hard to do anything with a 55G due to it only being 13" depth (front to back) I have extremely good luck with LED's and there is no going back for me. For either a 75G or 90G I would do the Photon 32. The 48" is going to have a lot of light spillage at either end of the tank. The same goes for using this light on a 55G..... you'll probably end up having a lot of light spillage on the front and back due to the 13" depth. A 12" to 16" fixture will do approximately 24" x 24". Also I would probably put the 90 degree optics on it and hang it anywhere from 8' to 12" off of the water. If you need to be less than 8" than I would just do 120 degrees!
