Don't they look green because they reflect most green wavelengths?

- ncmncm 7y agoYes, they don't use green. Or infrared, beyond 700nm. I don't know if they reflect the IR like they do the green. Conversion efficiency of the part they do use can't be more than a few percent, so they probably radiate in IR. Converting IR radiating from plants, as suggested in TFA, thus seems like a good idea.
