I just added a fourth shop light above my 30 gallon tank- looks much better, less of a spot light effect. I still for some reason don't mind the look of the domes on top, kind of an industrial look. I still cant wait to get a bar to hang these on though as it's a pain to take them all off the cover when I want to open it up... Anyone else want to post some pictures of this set-up? I'd love to see what other ideas are floating around here.
