I don't know, as a neuroscientist this is very confusing. Blue light generally is linked to arousal, as in this study for instance: https://pubmed.ncbi.nlm.nih.gov/32973462/

I wonder if there is some paradoxical effect if you put in a lot of blue light you get a decrease in arousal? Perhaps it could also be something like repetition suppression, where there is a lot of activity and arousal initially, but this causes a backlash and you get a relaxing effect?

Or maybe it's all just placebo.

16 candlepower just doesn't seem like a powerful light. That's around 1800 lumens if unfocused.

Sometimes I can distract myself with a computer screen and I don't notice chronic pains but I don't think it's the blue light doing it.

This would explain why so many people were dazed and confused by the PC tower blue LED craze of the early 2000s.

I wouldn't claim dazed or confused for myself, but I _could_ read easily by them on my machines[1]. So I had make sure two were asleep, and the third…well, it thought it should blink a steady 1 Hz while in sleep. That one was also the brightest. There was no setting for the blink, so I had to unplug the LED to sleep.
