I vaguely remember fluorescents at gas stations & private lots.
They used tubes & were set at a 45 deg angle.
The big thing especially out west is the BIG telescopes can be
made useless by some lighting for some types of research.
Been a big push for years to change out the bad lighting & make
it much more directional.

I sure would like darker skies. You can still see the milky here way but
the sky glow is closing in on us.
