But for grow lights they're great. They are more carefully tailored
to specific wavelengths. Plus, the cooler operating temperature means
you can put them closer, meaning less of the light is wasted into the
surrounding environment.

Also, some of the newer LEDs are more efficient than fluorescents.

Plus, they last a long, long time, and are dimmable.
