Cities are swapping traditional light bulbs for more energy-efficient brighter LEDs. The rise of these blue LEDs are creating problems for our night sky and our health.
This is not at all a LED problem. It is just very poor execution. When we switched to LED in our and neighboring cities the light pollution went down very noticably. The switch should be used to use light smarter, not just blast more with higher efficiency. We now have some streets that even have motion sensing and dim to 5% power when not in use.
