Experimenting with night lights
“Light-pollution activists and governments have been very focused on street lighting, and that makes sense because it’s probably the biggest single source and the government has direct control over it,” Kyba said. “But my worry is that most of the growth in light is coming from other applications. If we want to reduce the environmental impact of outdoor lighting, it’s not good enough to change to LED streetlights and then stop. We need to think critically about all the different types of light sources there are.”

Re: Experimenting with night lights
Some businesses here have put borders of LEDs around their windows. They tend to be low end places, but there are still many of them.
Even churches are erecting large animated LED signboards to replace the old smaller signs that had modest floodlights.
Where are those that allegedly knock down the grid?

Re: Experimenting with night lights
Interesting that street lights have such a small effect, pity as it is the most controllable.
Cheers,
