I found this article interesting. It seems the switch to LED may not be as substantial with reducing light pollution as we thought mostly because the cost savings are pushing higher implementation. Maybe we need regulations around the amount of lighting allowed or soon no one will know what true darkness is.

An excerpt and full article link below.

Researchers have been documenting the steady growth of artificial lighting ever since it was invented, and they’ve been wondering when the trend might stop. During the second half of the 20th century, electric light grew at an estimated rate of 3 to 6 percent per year. According to the new study, Earth’s artificially lit outdoor areas grew by 2.2 percent each year from 2012 to 2015, with a total radiance growth of 1.8 percent each year. During this span, nearly 60 countries experienced rapid increases in nighttime illumination between 110 to 150 percent, while another 20 countries experienced growth rates as high as 150 percent or more. Nearly 40 remained stable, with only 16 countries experiencing decreasing rates of nighttime illumination.

It's a hopeless situation...
