I have a tank that is going to be set up next weekend. I was wondering if a t5 light would be strong enough. 5 bulbs at 39 watts apiece. The tank they would go over is 2 feet deep. The new tank has a low profile canopy that i like the look of and would be a PITA to try to use my current lighting of a hanging 250 watt halide and 2 39 watt t5 atinics.
