The new version gives me problems every evening. I have the setting to "work late" - because that's what I do - and it kicks in properly. However, regularly at midnight it abruptly changes back to daytime colors, then goes down again, then up once more for a short peak. It really drives me crazy and "wakes me up".
The last version did not have this problem - at least not for me.

The latest version of f.lux has some nice enhancements. In particular I like the ability to disable it on a per application basis so that, if I'm working in Photoshop, for instance, it will not kick in and distort the color space.

The ability to customize the color used at night time is probably it's strongest feature. This enables me to set it to suit my preference rather than use the default settings. The new version takes a little time to tweak, given the new variables, sunset and bedtime, but it's well worth the effort.

I love this app when working at night. So much easier on the eyes than my iMac's default settings.

My main problem with f.lux has always been remembering to keep it switched off when watching a movie or using graphics software. This update addresses that problem, allowing you to disable f.lux for the rest of the night rather than one hour, and also for individual apps: just select Disable from the f.lux menu and the current app will be excluded. I'd prefer to have an editable list of exluded apps in the preferences, but this is a workable solution.

A great little application that's a 'must have' for those of us who sometimes work late.

Nifty little app that automatically color-shifts your computer screen for nighttime use. It's easy to turn f.lux on and off without quitting the program. It's both stable and polite. Since f.lux doesn't DIM the screen, I use it combination with the screen dimmer Shady. When dimming is off, your screen looks normal.

Features I hope the developer will add: a setting for white LED bulbs; ability to change the color temperature to red to preserve your night vision; and an integrated dimmer (so I can use one program instead of two).

Excellent little app, and I tested a bunch of them before picking this as the best. Stable, easy to use, can dim your screen WAY down, and doesn't affect the screen brighteness or color at the brightest setting. Plus you can just switch it off to watch a movie, and keep your settings. I use it in combination with f.lux, which color-shifts the screen but doesn't dim it.

Oops, I thought I was on the Shady page; this was my review for Shady. I have contacted support and am trying to get this removed. (And why isn't there an easy and obvious way to do that, at least within the first 5 minutes of posting? Hello, MacUpdate!)

I will never go back. Worth jailbreaking iPhone just for access to F.lux as well.

Great app!
The only improvement I could hope for would be to add different durations for the dim effect (2 or 3 hours).
For those having blinks if used together with Shades, you can instead use Shadeit! (version 1.1) which doesn't conflict with F.lux. ;-)

IMPORTANT NOTE: there seems to have been some confusion somewhere... What I wrote about Shadeit! version 1.1 was indeed about Shadeit (without "!") version 1.1 now available there http://www.dsd.net/prod/mac/shadeit.php and not being free!
Instead, Shadeit! version 1.1 is not a dimmer but a black screensaver.

Wonderful application! Why I haven't found it earlier? My eyes love it.

You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better. Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.
