Dark north mode

Just going to chime in here and add my request for a feature that will allow extended daylight hours. I also live in Canada, and the sun goes down before I leave the office. I work in graphic design where color is important, so I'd prefer if there was a way to postpone the flux "sunset" so it didn't happen as soon as the sun goes down. I'm not sure what the best option would be, but being able to set a custom sunset and bed time would be awesome!

This is a "frequently asked question", and I think the f.lux team has some ideas about it. In the meantime, just set your location to somewhere in the south. The closer to the Equator you get, the more stable the sunset time will be. You can adjust what time it happens by moving farther east or west. For example, if you live in Denmark, I hear that Lolodorf in Cameroon is a lovely place to move your circadian rhythms to. Love the name, anyway.

I think I'm going to add a preset for the next f.lux for people far from the equator.
Current guess is that the sunset setting should be more mild (like 4500K or 5000K) and then we can rely more on the "bedtime" setting to avoid light before bed.
Love to hear any feedback of how this would work for you.
What I do in the winter is simulate a longer daytime with bright daylight-coloured lights. I think it helps prevent "the winter blues". I turn them off around 7pm, and use less bright tungsten coloured lights. Then an hour or two before bed, I turn those off too, and just have a small lamp with Rosco orange gel over it, which is close to the 1900K bedtime colour. Probably most people in the North do something similar - when it's 3pm and already dark, naturally you turn on a bunch of lights - we aren't living in caves anymore! But in the evening, they start to get dimmed or turned off, and a warmer colour feels more natural. Using f.lux probably makes people more aware that they should consider dimming/warming the lights even more, as the day winds down.
I've got f.lux to follow along - actually, it usually reminds me to change my lighting - by setting my location closer to the equator. So my screen colour more or less matches my lighting environment. It took some slightly annoying trial-and-error to get the right location, but now that I've got it set, I actually like that my "virtual sunset" does change a bit with the season - just not so extreme - rather than being always at 7pm. But I think most people would be happy to choose a fixed sunset time that corresponds with their working hours and so on, even if it has to be adjusted a few times a year.
Personally I wouldn't have use for a profile that goes to 4500K from the afternoon until "bedtime". I think it would only work for people who in the winter keep daylight-coloured lights on until just before bed, but I'd encourage them to switch to warmer lights in the evening instead. And in the summer, sometimes bedtime comes before the sun goes down...
I guess the bottom line is that it would be nice to have a more straightforward way of choosing a sunset time for f.lux that matches what people in the North simulate with electric lighting or curtains. Other than that, we're just normal people!

Just a suggestion - something like this maybe?

Yes we'll look into this some more - sounds like for sure there is something you're doing in between "sun is down" and "getting ready for bed" more like the 12-12 equinox schedule.

"Then an hour or two before bed, I turn those off too, and just have a small lamp with Rosco orange gel over it, which is close to the 1900K bedtime colour."I'd seriously like to see this lamp!! I'd say the easiest way to upload would be Imgur.

@timpster https://www.rosco.com/filters/cinegel.cfm?CategoryID=2 lots of spectral charts here

@lorna Wow I really like that! I may have to get a few bits and pieces of it. Cool, I clicked "About Us" and they have areas to ship from TX, which is about as far west as I'll go when getting stuff shipped to me. I like it because it's a central location and it's fair for most people, and well, great stuff comes from Texas!

@timpster it's just a little Ikea lamp with a normal 4W warm LED bulb. I taped a piece of Rosco gel around it, very low-tech! You should be able to buy sheets of Roso or Lee gel filters in local camera stores, or places that sell DJ or theatre lights. Should be US $5-10 for a good sized piece.

@Elhem-Enohpi Cool, very energy efficient!
