I currently use 4 – daystar ac’s with 600w hps lamps, and lumatek electronic 240v ballasts, in a 6′ x 8′ area. I have them over an aeroflo 60. I started with two, and found that the substantial growth I was enjoying needed more side light. I have them ducted all in series with a 6″ can fan, and even in the extreme heat of the AZ summer, they perform very well. I run the lights at night ducted to the outside (in and out), and I have to say that I was surprised at how cool they run. I think that the smaller design (over the radient) keeps the light tight. The fixtures I purchased came pre-wired and that is a plus. I would strongly recommend both the daystar ac and the radient ac to anyone who needs good light control and great cooling capacity. One thing that I would change is I would like a lip on the flange for the duct to better attach to. This would better facilitate the duct attachment and would lessen the chances of the duct from detaching from the fixture. I use insulated flexable duct not the aluminum ducting sold at the H-store. I have had the duct seperate from the fixture several times while changing the height of the fixture. This can be a problem when some of the fixtures are over plants that cannot be moved easily. …DFR

STANDARDIZED LIPS AND FLANGES NOW!!!!!!!!!! Not just reflectors, but filters, and fans! (we can dream) Hey, but giving a testament to lights in AZ is very worthy. Thanks!
