That wouldn’t be possible to get a higher output of the suns energy after going through a solar panel as well as a lighting circuit.
Plants benefit more from the intensity of light rather than a slightly preferable spectrum.

However, GP may be right about the conversion efficiency destroying any gains that you might get from re-emitting light in only those wavelengths. The energy conversion efficiency of even the most efficient LEDs seems to only be about 50%, with the rest emitted as heat. (Source: just a quick Google, so take with a grain of salt) And then you've got the solar panel efficiency on top of that, plus any necessary voltage conversion. Definitely quite a tough ask.
