If you look at the spectrum of white LEDs they have a much higher blue light content than compared to other lighting technologies. Often it's an other peak in the spectrum.
Also a lot of street lights have been replaced with LEDs, although probably better than Sodium Vapor since that light source has pretty narrow spectrum.
Probably means we should all be using warmer LEDs, instead of like 5000K, 4000K ect... for night lighting.
