I just felt a jolt of anxiety reading this. I feel physically unwell when in a room lit by 6000K "daylight" bulbs, and even imagining being in such a room gives me a twinge.

I don't know how I respond to these "blue pump" LEDs; are they currently on the market? How would I know whether a given bulb uses this technology? Maybe I'm OK with them (fingers crossed).

The difference between LED bulbs cannot possibly be a major contributor to CO2 emmissions. If they're going to be draconian about this, look forward to "15 minute cities" where you're not allowed to drive outside of your zone, since that would save orders of magnitude more energy.

made a small "high CRI desk lamp" using a portable LED light brick and a flexible gooseneck stand (https://www.bhphotovideo.com/c/product/1713648-REG/smallrig_... / https://www.bhphotovideo.com/c/product/1580737-REG/raya_frb_...)

you can change the temperature of the light using the small OLED display on the back and the dial to tune it, it's not super accurate but it's enough for me to be able to tell say when I set it to 4000K, it gives me a reference when comparing to 5000K or something

I think most of us share this vulnerability.

I have an inverse issue where I get uncontrollably tired from warm colored lighting to the point of needing to nap.

Same here. I have bright daylight lights in the kitchen part - it looks like a lighthouse because this is a place I need to see.

The living room is warmer but still very much daylight, otherwise I would sleep there all the time

Yeah man I seem to be sensitive to both: red lights (or red shifted monitors) during the day make me feel fatigued and sluggish; white and blue lights at night make me feel anxious and vulnerable.

I'm surprised to read your description of 15 minute cities. The idea behind them is to make daily neccesities available within 15 minutes of travel by foot, bike or public transport. Not allowing people to drive (cars) out of some designated zone would be kind of silly, since the idea is to make stuff that would be within such a "zone" available without a car. See the Wikipedia article: https://en.wikipedia.org/wiki/15-minute_city The way you describe them sounds similiar to the "Conspiracy theories" section.
