(Michael from f.lux): this kind of thing is necessary for most buildings, because otherwise people don't get a "day" signal when they spend time indoors. Most of us spend >90% of our time inside. However, we shouldn't mess with light levels like these (or even somewhat lower ones) without some limits, and the main one is some automatic timing to turn things down after it gets too late. Otherwise you will find yoursel…

Have you considered manufacturing f.lux for home lighting, such as a wall-mounted controller for Hue or Ikea bulbs that changes color spectrum depending on time of day? Or possibly bulbs with f.lux build in, so no external controller is required?
During the day time all my bulbs are at 6000K and 100% brightness, at 6pm the bulbs in my bedroom/office dip to around 4500K and 50% brightness, and at 8pm to 2700K and minimum brightness (we have a toddler).
In my kitchen/living room during the day it's the same, at 8pm to 4500K at 50% brightness and at 11:30pm to 4500K at minimum brightness.
I considered having the schedule run on when the sun sets, but in my location that is 10pm in the summer and 4pm in the winter so it doesn't really work at the extremes (I have the same complaint with tooks like f.lux as well :D).
I'm extremely light sensitive, and so have built quite a few DIY solutions in order to alleviate my S-A-D symptoms. One of my systems may have been a bit over powered and over used, as I developed what a doctor friend later diagnosed as "light induced hypomania", which was quite an experience. Experiment at your own risk.
> One of my systems may have been a bit over powered and over used, as I developed what a doctor friend later diagnosed as "light induced hypomania", I would note that light-therapy lamps for SAD have clear instructions to not sit in front of them for more than an hour-or-so at a time. Your body really does just go on producing more dopamine as long as you're sitting there.

Hey Michael, first off I love f.lux and use it every day. I have a question relating to your comment: is there any reason not to have an extremely high lumen smart light fixture which progressively dims throughout the day and syncs with the solar cycle in the user’s area? That seems like the holy grail, and is simply a combination of Philip’s Hue/LIFX tech and the bulb in the OP.
Yes, I think that's right - we have 20,000 lumens in our office and it is pretty cool, except you can't see your screen when it's up all the way. I still prefer daylighting, because it changes the angle of the light and everything else through the day. A couple things: I don't think you necessarily need more light in the morning if you have a well-defined (artificial or real) sunset, and if you've reduced light at ni…

They are using these underground to help simulate the true daylight experience. Basically a smart led version of a traditional roof sunlight: https://www.youtube.com/watch?v=aJ4TJ4-kkDw

Can you elaborate ? 20k lumens doesn't seem like that much ...
I see residential interior decorating guidelines at about 20 lumens per square foot for non-intense areas like living rooms[1], etc., which implies a 1000 sf office (smallish) conservatively lit with 20k lumens.
I just put 11k lumens of background lighting in a 400sf living room and I am worried it's a bit under-lit, given 12 foot ceilings.
I think that perhaps you are talking about something different than I think you are ?
[1] As opposed to kitchens where I see 50-80 lumens per square foot recommended...

> cancer progresses much faster in summer than in winter This sounds fascinating. Do you have a source? Btw, I love f.lux and have been using it since probably like 2010, possibly earlier. Its basically the first thing I install on any computer.

Regarding only natural light, what would be the ideal latitude region for psychology year-round?
At 30°N and 30°S days swing between 10 hours to 14 hours through a year. Would it be ideal to live in between 30°N and 30°S, or would you expand/shrink the range?
ps. Any resources on geography-psychology relationships would be appreciated.
I usually eschew labels, preferring simply "sleep weirdo", but I fit the pattern of "Non-24 Sleep-Wake Disorder", with my sleep and waking times drifting progressively later at semi-regular intervals. The result is that I'm often awake through the night. (This week I'm going to bed around 9:00 a.m.) Even with that, I've noticed some pretty big productivity swings based on the season. Interestingly, this hit me very h…
"I keep going back to halogen as the sweet-spot between black-body radiation and energy efficiency." Permies put out an article arguing for incandescent if your goal is light AND warmth: From https://richsoil.com/electric-heat.jsp - "This last one was the most important. A standard incandescent light bulb heats something to the point that it glows white hot. So I used this to heat myself and it doubled as a light sou…
