> Too much light ... makes us less safe by creating harsh shadows and giving criminals a place to hide. LMAO

  It does link a couple studies to back up that claim. Critiques of those studies or evidence for the opposite would contribute to the conversation; this does not.

  Used to use this to great effect for capture the flag when I was a kid. We used to do it across the whole neighborhood. We realized that standing in shadows cast near street lights were excellent places to just stand and watch the other team. The bright light makes your eyes adjust and the shadows from nearby tree trunks become black voids.

  This is an issue driving the mistaken belief that we need more and more light, especially bright blue LEDs. The LEDs have a hard cutoff between light and dark zones, and both the blue tint and the excessive brightness of the lights decrease your night vision and make your eyes become more unable to see anything outside of these small lit zones.

    The low-frequency flicker also reduces motion resolution, and these LED lights are typically narrowband, meaning the CRI (Color Reproduction Index) is typically low enough that it meaningfully affects resolution across the board, from motion resolution to shape resolution. Typically under these bright blue narrowband LEDs I still find myself squinting and unable to make anything out, despite the intensity of the light. The whole industry of public lighting is a massive scam that is completely out of touch with the research.
