I owned a couple SolarFlares a few years ago and they worked fine. You might want to consider Autocobs. I have the 3500K which comes ready to hang, or you can get the finish build. Autocobs are silent, very efficient, generate less heat, low electrical draw, small and easy to move. You can check them out at
www.cobshop.net. Also lots of information in here under the "lights section" I have the 3500K lights. They are incredibly bright. I use one cob per plant.
