https://journals.sagepub.com/doi/abs/10.1177/074873049701200205 … very weird: nonhuman primate lives 9-10 seasonal photoperiod cycles (days getting short and then long again) and if you speed up those cycles its lifespan drops 30%. If you slowed down the photoperiod cycle could you *increase* lifespan?!

Nice! Much brighter than what I've done. You can probably get an app on your phone to estimate lux. This is only about 2000 lux at eye level, but people in the vicinity still found it unpleasant. Maybe a gradually brightening environment helps adjust.https://mobile.twitter.com/mchapiro/status/1082023050504155137 …

I'm also interested in getting the right spectrum, maybe with a peak to match melanopic sensitivity. Almost all white LEDs and SAD lights have a peak around 440 nm and a big dip around 480 nm where sensitivity peaks.https://mobile.twitter.com/mchapiro/status/1139944338773778432 …
