What you have to keep in mind when choosing any light for any tank:
If you have moderate lighting (like what we're talking about here) then to balance this properly with nutrition and co2 (your fish) is very very simple.
Double your light and likely the co2 from your fish won't be enough so you will have to substitute with a liquid possibly, that's getting kinda tricky.
Triple the lights and you will need higher amounts of ferts (the plant nutrition needed for good health) AND a co2 system. While adding it all is easy part, BALANCE this is hard, done wrong this can/will easly & quickly turn your nicely planted tank in a neat little show case of algae.
So in short and simple: Less lights is easier to maintain AND have great plant growth AND happy fish.
FYI naturally fish are used to dim waters not bright high output 5x flood lamps from the stadium

As for your plant selection: What fish do you have and what plants do you already have? Or is there something in particular you see on one of my tanks you like?
