Hey Mike, I am no expert and do not know what you are wanting to keep. PAR readings with one of the 72W modules to a 42" depth should be okay for some species, but knowing their specific lighting requirements and placement become key. A pair of these LED modules will definitely be stronger and so allow you to keep more light demanding species. That said...there are other LED fixtures that will provide more light, but will also put a larger dent in your pocket book.
