Yeah, that was my understanding too. More developing nations are using LED street lighting that's powered by solar panels. Just do any youtube search on "driving in xxxx" (I've searched "driving in Liberia" and "driving in Port-au-Prince") and you'll see LED street light fixtures with solar panels on the top. So it's not that the LED street lights are shining more light up into the sky per se (in fact, they're better at aiming the light downward), but more and more areas of the world are using LED street lights.
