good luck with the gamble.
if you want another LED to consider, then I might suggest the finnex ray2.
I think the amount of light produced (PAR or whatever) is higher than the zoomed, so will give you better options.
but a 30H is going to be problematic to grow a carpet, whatever lighting you might choose.
I actually like this one a bit better. It seems like it will give me a better output but hopefully not so much that it becomes an algae disaster.
