thank you! this is a nice and useful post.
a few related recommendations from personal experience:
these bulbs live further down the spectrum of more-lumen/less-CRI; i like them and use them at home: https://www.amazon.com/SANSI-Equivalent-Technology-Non-Dimmable-Efficient/dp/B0BV6CQ8JL
i have not experimented much with higher CRI bulbs, but i suspect that i’m sufficiently deuteranomalous that i wouldn’t get much value from them (low-confidence)
very quiet, effective, air purifier, also has an app to enable scheduling etc. i have one in my office and bedroom.
quiet, effective window ac, has app to enable scheduling etc.
reflective insulation—i put it on windows that are not used as such to prevent heat ingress and reduce light seepage through blackout curtains (i like it very dark when sleeping)

this is a big roll
some potential cilotoxicity for povidone iodine at high concentrations

ok- looking ranges: https://pubmed.ncbi.nlm.nih.gov/32520599/
looks effective above 0.5%. i mix for 0.75% to keep a bit of tolerance for mixing error while staying below 1% for nasal use.
if you are diluting an otc product to get desired concentrations, check for toxicity of additives esp if the product is marketed for external use only.
