I have the same setup as you LED wise from JBJ, They said its comparable to a 150watt metal halide, so I'd say yes, your good with a deresa or gigas at least...
I have the pro, I bought it used locally with a bad ballast for the hood for $150 tank/stand... I bought a new light ballast for $85 and its good to go. I think its a great tank and I love it so far...
