ensete Thank you for this. It’s given me a lot to think about in terms of how my spaces are configured.

There is truth to this. I can unscrew an incandescent bulb that is absolutely fine in one room's overhead lamp and put it into another rooms lamp, and there are major differences in eye comfort. As far as I can tell, all of the lamp sockets seem to consist of a simple wire and no further electronics.

ensete This dovetails into my theory that color of light has a major impact on our condition.

I wonder if the Avulux lenses the @bkdo uses might help?

Avulux's physicians and engineers designed a lens that filters up to 97% of painful, migraine-triggering blue, amber, and red light...

chahahc I want to try the ABSOLUTE SERIES 99 CRI LED Technology | Waveform Lighting you mentioned before. It has the violet LED chip that @KM brought to our attention.

I have no experience with LED strip lighting, but it is a project I am looking into.

Their literature from that page:

Traditional white LEDs use 455 nanometer blue die as the underlying light source, and a dual-phosphor mix of green and red phosphors to achieve a semi-full spectrum light output.

This results in what is commonly referred to as the "cyan gap" - where there is a lack of light energy in the region between blue and green wavelengths, and an overshoot of blue wavelength energy. A close look at color rendering scores such as CRI R12 will also reveal that blue colors may appear over or under-saturated.

ABSOLUTE SERIES™ LEDs utilize a different method of producing white light to eliminate the cyan gap and blue overshoot. By shifting the underlying light source wavelength to a violet 420 nm die, a fuller, wider spectrum is made possible. This also provides energy coverage down to the nUV wavelength range.

The spectrum explanation is also strengthened in light of @KM finding that Quantum Dots can reduce LED backlight brightness associated pain.
