i have a 60gal tall looking to upgrade my lighting. can't decide on 2 kessil a150w or the reef radiance lumentek pro 240. 2 kessils should do it and i really like the color they put out. but i like the programmability the reef radiance provides. I wasn't sure if it would have enough coverage on a 48" tank since it is only about 31". I could change the optics to 120deg.....not sure what to go with...
