Bioluminescence can cause photosynthesis, it has been confirmed. But is it feasible to grow algae, or some other plant, by the light of bioluminescence alone?
Is it technically feasible with existing animals? The best I could find for data was this article about fireflies. It suggests you need 35,000 to get the effect of a lightbulb. Ideally, we'd want to work out what lux bioluminescence is capable of producing.
Theoretically, the best way to work this out is to work out the optimal output of luciferin in a lab, then work out how well an animal could replicate that. But, so far, I'm having difficulty finding any study on the potential brightness of luciferin.
