I'm not sure where to post this so I just decided here. I am curious about full spectrum lighting. There doesn't seem to be any good information on how much light is needed for a particular space. The aviary room I am making is 880 cubic feet. Does anyone know how many of the Philips full spectrum tubes are needed to provide adequate light for birds in that size space? Last night I ordered one fixture that will hold two, four foot bulbs. Is that enough or should I add more?

Thanks,
