I don't think it will be enough, which is why i recommended 3 light fixtures of 168 watts. Each fixture is 2 T5 bulbs (which IMO are better than using T8's) at 28 watts each ( 2x28watts=56watts, 56wattsx3=128watts). Using 2 fixtures for the entire photo period (112 watts/50gallons=2.23wpg) and the third for a noon burst (168 watts/50gallons=3.36wpg) to prevent algae blooms that occur with newly setup aquariums.
Not sure where you got 84watts but using a range of 112-168 (2.23wpg-3.36wpg) will be more than enough and he will not be limited on plants. To me it makes more sense spending approximately $370 for EVERYTHING (pressurized Co2, lighting, substrate, diffuser) than spending $123.99-$238.81 on lighting alone. But it is his choice, this is just my $.02.
