LEDs are better than incandescent lights, maybe on par with
fluorescents, and don't need a minimum voltage to run the electronic
ballasts. I think 100 watts would be the output for an average person
and even that might be pushing it for a person in a developing country
who may not have enough good nutrition. At 100 watts, solar panels start
to be a major investment and don't work too good at night or on hazy
overcast days.
How did we wind up here?
Cross posting.
