A one bulb T8 light will work, if you keep it about a foot inches above the substrate. Otherwise, even that will be too much light for a non-CO2 tank. Don't even think about any T5 lights. Screw-in CFL bulbs will work, if they are very low in wattage, especially if they have no reflectors. If you have 2 inches of substrate in that tank the light will only be 6 inches from the substrate!

This might be one of the rare times when one of those cheap panels of very low power LEDs might work.
