Time to upgrade my grow lights
Currently using a 400W sodium light in an outdoor floodlight fixture.
I'm not sure how many watts it actually uses; probably close to 500W and although the bulb is very efficient the fixture is not. So I'm thinking about one of these (haven't decided which of the 2 yet): http://store.yahoo.com/pro-lighting/4lat5flhibay.html http://www.fullspectrumsolutions.com...res_35_ctg.htm (the 4-lamp version) What do you think? The fixture from FullSpectrum has a more efficient ballast, but the energy payback would take a long time. Also I wonder if the included 5900K lamps produce enough red spectrum for efficient use as a grow light. Of course I could pull 1 or 2 of the lamps out and keep them as spares and replace with 2700K or 3000K tubes. Bob |

LED plant grow lights are very suitable for any type of aquarium. These mounted lighting system has a higher initial cost. However, they have a reputation for more than 10 times lasting compact fluorescent lamps.
