I think those are very good lights, but the much newer Lumigrow ES is brighter with higher power LED's and true 660 nm red...top of the food chain right now. Also, that light you mention the probloom 1000 uses 430 watts total and must be water cooled which I'm guessing is a paint in the butt, also $1900 each! I heard the company that makes them is going out of business anyways and having legal issues. (was in one of the calibuddz threads)
