Shielding of lights is an important aspect. Instead of having an open light, flat lights or shielded lights that prevent spill upward are crucial. They direct light to the ground, and not up into the sky.
In Canberra, the Australian Capital Territory government and light operator Omexom have been changing streetlights to do exactly this – no upward spill, and controllable lights.
In doing so, Canberra has reduced its light pollution by about 30% in only a few years, as my colleagues and I report in a forthcoming paper.
Same here. I was in the countryside recently, thought I’d be able to see the Perseid meteor shower but it was impossible: even the little village I was in had bright white streetlights on all night along every road, even the ones with no houses! This is a village where you rarely see anyone walking, even during the day. So why the streetlights at 2 in the morning?
Contact the city hall. I was pleasantly surprised to see that here in France, many people are thinking the same, and that a lot of small towns switch off light after 2 am. It saves energy, and it helps night life.
I must say however that it is pretty spooky walking or even driving in a totally dark street in the middle of a small town!
