Current USA Nova Extreme T5HO X2 or Coralife 24 inch

Both of those lights are T5HO, not T5NO. And, a two bulb T5HO light is too much light for a non-CO2 tank, unless they are hanging about 8-10 inches above the top of the tank. Even T5NO 2 bulb fixtures might be too much light, but using the legs with the fixture might reduce the light down to the low light range.

What are your plans for the tank?

IMO you'd be better off with a PC fixture because both kinds of T5 lights are going to give you too much light. I've got a PC Coralife on my 37g and it does its job, my plants are growing, some several inches per week. But from my research, people think the reflectors aren't ideal and the Current Nova has good reflectors. You could also check out the AH Supply Bright Light kits.
