would normal flourescent light bulbs work for a light source for low light plants? Or would it be better just to use incandescent?
You are talking about the bulbs right? Generally speaking you want a bulb that is rated between 5000K and 10000K. Many household bulbs are rated below 5000K, often labled as 'coolwhite' and are less effective for aquarium use than the higher K bulbs.
:iagree:CFLs (compact flourescents) should work in your fixture. You can find them at Wallmart and most home improvement type stores. Check the K rating, 5000K to 10000K. Daylight 6700K bulbs are pretty common and would be a good way to go.
