What I have heard about the light is that it is a descent light but the bulbs need to be replaced on them. The stock bulbs that come with them arent the greatest (which most fixtures arent anyway).. Never had one so I cant help further then that.. sorry..
I have the 4 T5 fixture with LED moon lilghting and its a really great fixture. I need to change out the bulbs soon, but the soft corals I have in my tank are growing well.
