My main issue with f.lux (and the reason I don't use it) is that you can't configure it to wait until a certain time to start with the transition. When I go to bed at 11 pm, I would like f.lux to start its one hour transition at 9 pm so that I don't see that much cold light the last two hours before sleep. And in the morning it should start directly with the settings for the day, without any transition. Tying it to s…

Similar issue here. I love it but it starts too early and clicking the "turn off for a hour" setting all the time was just a pain. I like that it initially tries to auto-tune itself, but I'd enjoy it even more if it had a customizable schedule. And this might defeat the purpose, but if I could configure it to know what Spaces it was in in OS X, I could still design and not have to turn it off manually for just that o…

Pick a location on the equator, and offset it to your preferred schedule instead of your actual sunrise/sunset time.

Half the people in my office leave their laptop display at about 50% brightness all day. It drives me crazy -- I always want to go over and turn it all the way up. I like my monitors BRIGHT, but others say it bothers their eyes. You might be right...

That's kind of funny. I personally can have real issues with bright displays. Only in very light sun lit offices, I don't mind the brightness being up. When at home in the bat cave, I far prefer dimmer light. Some days my eyes are more sensitive, or perhaps getting used to dimmer displays make you more sensitive to bright ones. I used to use the transparant filter with compiz, just to take the edge of some glare/brig…

I've also found that having both a light and dark color theme is useful for your editor. I am currently using Solarized in Sublime Text.

It seems to work well, and if you read the description, it seems like a lot of effort has gone into matching the two versions.

This thing gets a lot of love by a bunch of folks here, so I gave it a good half year of trying. But it's just too annoying. Around 5pm, your display turns pinkish orange and it becomes a lot harder to see anything. Code gets harder to read, colors display wrong, video just fades to black. None of the advertised happiness ensues. The second half-year it remained installed, my only interaction with it was to notice it…

(author of f.lux here) Color adaptation actually takes about 2 minutes, and we transition by default in 20 seconds (some video cards use a ton of CPU during the transition time, so we pushed it a bit faster.) The slow transition option should help some people. Also a badly-calibrated monitor can give a very undesirable result color-wise, but a white page should look like your room lighting if we do things right.

I love f.lux, thank you. It's on my Mac and on my iPad. It'd be on my iPhone too if I could jailbreak the thing yet.

Oh and here is a bug that's been niggling at me. If you have your laptop plugged into an external display after the evening light kicks in, then unplug the laptop, it's in screaming bright normal colors on its own screen until you quit and restart f.lux. Same if you plug in the external screen in the evening.

Summary of feature requests so far: - default to a slower transition - support dimming too - Add an API - Sunset is fine, except in the winter Most of these are on our list but it is all good feedback!

An Android version, please. The clones available all suck. It annoys me that I could run flux on an iPhone, but not my Galaxy Nexus. :/

Am I the only one that keeps the same value for night and day? I have it set to 5400K regardless of the hour. I like the subtle warm glow to remain constant instead of fluctuate.

While a bright monitor can reduce the quality of your sleep at night, I actually read somewhere (sorry, can't find it now) that a bright monitor at daytime can be beneficial for your circadian rhythm if you don't get exposed to much sunlight otherwise.

In my opinion, it really depends on the brightness of your monitor(s). My iMac screen is rated at 350 nits, a.k.a. super-bright, so when Flux kicks in, I don't mind it if I'm working on that screen. On the other hand, my 2nd monitor is an el-cheapo Samsung I bought before I cared what "nits" meant, and is rated at 250 nits -- a significant difference. My typical workspace at night is, left screen (iMac) holds the bro…

So are you enjoying your new monitor?

(Have you tried calibrating both screens? flux should not affect brightness/gamma differently.)

> I wonder if there's some sort of genetic difference? Maybe some people just aren't sensitive to bright light in the evening? No, it's probably people not noticing that they have a problem and insisting that they don't. Happens all the time.

Maybe some things just aren't for everyone?

Things that depend on common human physiology rarely have exceptions...

It turns reddish gradually, so I don't really notice it. If I disable it at night, the sudden blueness hurts for a second, which implies there's some benefit to being redder.

In some WWII submarines, the sleeping room lined with bunks for the bulk of the staff, the lighting is red. Why? Because you can sleep in it easily -- it's always just red in that room because there are some day and night shifts even on a sub.

The story that I heard (from my army dad) about red lights for night work was that red lights cause less night blindness than white lights.

Wikipedia corroborates this story, but indicates that a Navy study (from the 1980's) didn't find strong support for the practice.
