The fact that cities are continuing to buy white streetlights that have intense green spectrum emissions despite light-pollution being a widespread and well-known issue, is beyond me. Even if you’re going for the energy efficiency of LEDs over the monochromatic sodium lights, it is not cost prohibitive to slightly adjust the spectrum. Instead we have stupidly bright lights high in green light that blow out night vision, that then break and turn purple. It pisses me off to no end.
