Sorry it has taken me so long to respond, I haven't been on here in a while. You are correct, the lighting is just a single 48" Beamswork "freshwater bright" fixture. I think the pictures represent the actual light pretty closely. Since it is a 135gal (72" long) there is a foot on each side that the fixture does not cover. I prefer a more subtle lighting effect so I have been really happy with this setup. Depending on how brightly lite you want your tank, you may want to go with two 3ft fixtures, or look into the brighter "double bright reef capable" fixtures.
