Are you telling me these streetlights didn't sprout here?

they have a sharp wavelength peak,
but they'll have a continuous spectrum superimposed on that as well. I think.
Any light coming from them will no doubt have been affected by other things by the time it hits your retina anyway.

the spectrum of a sodium street lamp apparently looks like this:

i'd love to get my hands on some streetlamp beans
imagine the fun you could have planting them in neighbours' gardens, or sneaking them into pot plants belonging to people you didn't like

or eating them! what'd that be like?

i'd swap my only cow for three of those beans
