The problem with LED lights for plants, is that LED lighting emits an incorrect color spectrum for plants. LED lighting is used alot for reefs and deep marine tanks. But aquatic plants grown in freshwater do not utilize the heavy blue light spectrum found in LEDs.
Now, maybe somewhere there is one that plants will like, but I don't know of it. The full spectrum (aka "daylight") T5s are very good for plants; I use those and compact fluorescents which are pretty intense lighting for freshwater. But I need the heavy duty lights b/c I keep a lot of red plants (high tech set up....CO2, nutrient dosings, blah blah blah)
