They’re fine if the owner has the sensitivity and range set appropriately.
My neighbour has decided to put 3 lights up that come on when it goes dark and stay on all night.
We live in a small village with very little light pollution and as such we enjoy quite a bit of star gazing. These lights have completely ruined this. What’s more they’ve built a wooden “studio” 2/3rds of the way down their garden (painted black & nicknamed the death star) with a light on the wall facing us. So when we sit on our decking at the back of our garage/garden room, the light shines directly into our eyes.
We can no longer watch nature at the bottom of our garden and can’t see any stars. Totally ruined one of the reasons we bought the house.
