Starting a 40 gallon long..
 
Would 1 T8 bulb be sufficient for a low to moderate plants? I know usually you would want 2 tubes over a 4ft aquarium, but with a 40 long being more shallow was wondering if 1 would do.

It depends upon the tube length, tank length and depth, and the type of tube. Assuming the tank length is 4 feet and height is 16 inches [you call it a 40g long], you could have one 48-inch T8 tube. A good Daylight tube around 6500K would suffice for low to moderate light plants. Crypts, green-leaf swords, Anubias, Java Fern, Java Moss, Brazilian Pennywort, and most floating plants would or should manage.

A single tube T5 with a 48-inch HO tube would open up options more, but shouldn't bee too much with a good cover of floating plants. Finding single-tube T5 fixtures is not easy.
