Why do you need 10,000 lumen to light a room? What sized room are your considering? And, if you are responding to your parent post, it says light enough to walk around. Even 100 lumens would be sufficient to walk around a 100 sq ft room.
- groby_b 12y agoOf course that's sufficient - but that's half of what moonlight provides. Given that you already can have that for free, I assume the plants are supposed to provide some improvement. Any light output that's a marked improvement will mean either large plants, or a surprisingly large chunk of the metabolism dedicated to light generation. I don't say it can't be done - my bio-sciences fu is too weak - but I'm somewhat skeptical given the pure numbers. I'll be happy to be proven wrong.
- hrjet 12y agoYou can rely on moonlight just about 5% of the nights, because of the monthly changes in moon phase, and nightly change in position due to earth's rotation. I am skeptical about the plants too, and like your calculations. But the numbers you have chosen seem too harsh.
