Today I stopped by BigAls and purchased a 24'' Coralife F/W T-5 Aqualight Double Strip Light. Looks much better than my old single strip 15 watt light. I am hoping the 3 java ferns in my tank right now will grow even more. I am planning on added many more plants soon and was just wondering if this lighting over my 20 gallon tank is considered low light, because I am not too sure about the difference of T-8, T-10, and T-5, etc.
you should be able to grow low and some medium light plants. i have one over a 20 long and able to grow a fair amount of plants. the difference between the different T bulbs is the size of the bulb. the smaller the bulb the more efficient it becomes.
If so, you have at least a medium light set up. <T5's are more efficient than T12, so that is like having 60W of NO T12's.> You should be able to grow quite a large selection of plants.

you will be very happy with your lights!! upgrading to t5 lighting is the bomb!! i think you can grow any medium light plant and if you put co2 in there then you could grow any high light plant aswell.
You are still fairly low light, but can probably grow the easier stem plants. Try growing Ludwigia Repens, Rotala Rotundifolia for starters, see how they do.
