if your tank is 48" or less there are plenty of good lights for $500 or less. nova extreme pros, sunpods, sundials, TEK T5's, Aquactinics TX5, sunlight supply or PFO metal halide pendants and dual ballast, any brand metal halide or T5 retro kits ect ect. some may go over slightly with the cost of bulbs but not much and well worth it.
