0.58 microEinsteins/Joule. Not bad, not good.

It is obviously penalized by making it's spectral distribution pretty (a lot 
of filters)
and having a lot of output in the yellow-green area.

It will grow plants great and the tank will look awesome, but it's far from 
the
best regarding making most out of the electricity put into it.
