I have been saying this for 20 years… now, someone has published something useful about it…

LED lights are horrific. My experience of them has been absolutely anti-health. They are the »wrong form of light. The shadows they cast are terrifying and wrongly ‘digital’, I cannot stand this form of light — it’s depressing, terrifying, and feels completely wrong to me as an organism, as an animal, and as someone with visual experience. The »frequency is abiotic… it damages my sense of well-being every time I am subjected to it. I would do almost anything to make it go away. It is an intrusive form of light-rape and I despise it.

“I started to confide in people that I was seeing things, that the light was wrong, and usually they knew exactly what I was talking about. Over lunch, a friend unspooled an epic account of his quest for dimmable bulbs that would actually dim. A stranger in a shared taxi forwarded me a blog post he’d written about his conviction that the color of objects lit by LEDs was washed out and about his incredulity at how fast they failed.”
