I like darkness at night. I don’t like my neighbor’s lights glaring into my windows; I don’t like the orange glow in the sky from the shopping center parking lot after all the stores are closed.
My town has streetlights everywhere; the next town only at intersections. The former feels safer for walking, but really there is no difference.
IMNHO, street lights should not scatter upward.
And Christmas lights are beautiful. So is a night-lit city from the air as you land, or Manhattan and its bridges from FDR drive.
:: street lights should not scatter upward ::
RTF science negates your plea. Like RTF-Radar emissions, “scatter” in all directions is the price of transmission.
Buffers, caps, shields and mirrors won’t stop light from “bouncing” into the local sky.
Y’all can try, but, you won’t succeed.
