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 night to a lower level.
We add light to the morning so that we can add as much light as we want at night - the two cancel out. But I think it would be better to really try to design the evening to look different than the workday. Lights should change, and they mostly don't.
There are for sure some people with long internal clocks (DSPD/N24) who need very custom lighting schedules to have a normal schedule, but I think if we make the overall signal stronger (more day to night contrast), a lot of the differences between night owls and early birds would become smaller.
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...
My office is not that big, so yes it is quite intense there. But, I should say just that system is capable of delivering >500 vertical melanopic lux (which is a metric based on holding the meter vertically rather than pointing "up"), and this feels remarkably bright.
