I was growing mine in an aquaclear 300 (200? not the big big model, the biggest one with the small impeller though, whatever that is.. about 6" wide for the media compartment), with 2x9W PC over top of it, and I could not keep up with the pruning, it grew so fast.
So a 15W NO might do the trick, it just depends on how high up the light is. My guess is it would keep it alive, but not grow as fast as it could as compared to brighter lighting.
