Impact of LEDs on Light Pollution
As infrastructure increases globally, artificial lighting is available in a larger and larger area. Developing countries chose LED lighting wrongly believing that LEDs are a long-term, more sustainable lighting solution. However, a huge problem with LEDs is their color. Making the switch from sodium lights that are orange-yellow in color, to the higher powered, bluish-white LEDs worsens light pollution. Blue light can scatter farther into the sky, which makes it more dangerous to both mammals and insects.
