What is the best solution for circadian-friendly artificial light?

@Cécilia

The problem is that just a bit of melanopic light (which peaks at about 480 nm) can disrupt melatonin production (and disrupt circadian bio-rhythms) significantly;

thank you for sharing your research and ideas

Im in USA, I looked at Sunlike, but the price stopped me from proceeding.

300hz flicker would be a deal breaker for me.

I tried the original Phillips hue bulbs… they work OK, but, my phone shows ripple that is not present in Incandescent.

I gave up on LED options until I hear of one that works, flicker free, w high CRI, at a reasonable price.

Here is a recent post about some 3000k LED strip lights… the feature I find lacking, is that the CRI is not 90+

How do you store your flashlights?

They’re USB, so they could run off a battery. I have some shelves where I charge all sorts of stuff next to this so they’re plugged into AC->USB. They cost more than others but the sections were almost the same measurement as the shelves, so I was able to get 2 strips above each shelf. I just had to notch the edges of the shelves w/ a file to pass the wire. https://www.amazon.com/gp/product/B08C7BJ3GF/

So I just use 100 CRI 3000k Incandescent for my house lighting. It does not seem to cause me any circadian issues, that are associated with LEDs
