Do what many seem to do; swap the modest lights for 500watt Eye Burners.

Or more likely these days 20 W LED eye burners that squirt light out
approaching 180 degrees and are next to impossible to control the
light from. It ought to be made illegal to sell floodlights with more
than a 90 degree beam width.


It would be a good idea. I have one pointing almost 80 derees down to avoid
spill beyong my boundary fence. Some sort of "barn door" shutters would
belp. Unfortunately I think some people see "lighting up the air" as a
benefit.
