Simple streetlight hack could protect astronomy from urban light pollution

Some of the newer street lamps in my area have smaller light for pedestrians! They're mounted at human height and shine down on the sidewalk.

Motion sensing, I find, similar to LED technology, is often used more for increasing lighting levels rather than decreasing. My pet peeve are people who have motion sensors that activate their 20k lumen floodlights based on motion on the public sidewalk. Cities should not allow those.

Isn't that just a matter of perspective [whether the presence of motion is used to increase lighting or the absence of it is used to decrease]?
