If you are on a budget and want powerful led lighting then maybe do a simple multi chip build? It´s fun if you are into building stuff... Just find some old computer heatsinks and ad driver + leds and go from there.
My plants are bubbling away nicely under simple cheap cold white leds.
Edit: Will it be open top?
