Right now i have 2 15watt lights that came with the tank, sister got it from wallyworld for me for xmas. But im looking at getting a coralife lunar model, its expensive, i also heard of a few people on the site running a Jebo Oddysea light, its cheap but it seems to work out for them and no complaints. Im probably going to go with the Jebo for now, and once i get the Sup postion at my job then i will get some MH for it.
