LED Lighting

Why don't more people use LED grow lights? Apparently they still have all the same light power of HPS and metal halide. All while using between 70 and 80% less energy, and dissipating almost no heat. Which makes it seem like the obvious choice, but i must be missing something if i'm one of the few using LED.
