Sure, but where does the energy for that light come from? If the answer is burning things (this is the most likely answer today!) then you are making the world worse. Renewable answers all go back to the sun so why not use the sun directly and avoid all the inefficiencies from turning the sun into electric and then back into light? Which leaves nuclear - which is dieing because of expense.
Artificial lighting exists.

Photosynthesis only uses a couple frequencies. Using solar to generate electricity and feed that into target LEDs can be significantly more efficient.
