Operation and function

The f.lux program automatically adjusts the color reproduction of your monitor to the time of day. If you don't like the standard setting, you can adjust the color temperature of your screen individually. Select "Daytime", "Sunset" or "Bedtime" and set the desired color temperature with the slider. You can also choose when to get up. Depending on the setting, the automatic color temperature control is further adapted.

In addition, there are a few more options available to you via the icon in the notification area of ​​your system. For example, you can use the "Darkroom" mode for light-sensitive environments or the "Movie mode" for watching films. You can also deactivate the software for an hour, a specific application or until the next sunrise.

The program also has a so-called "white list". There you enter programs and apps in which the application should automatically deactivate. This is particularly useful for graphics programs and games, especially since f.lux can cause a loss of the frame rate.

Availability

The program is available for common systems such as Windows, Linux, macOS and Android and is completely free of charge and free of advertising. For the Android version, however, you must have activated root rights on your smartphone. The software is only available in English.

Conclusion

f.lux is great software that makes working at dawn or dusk or at night much more pleasant. It effectively avoids eye strain. It is also nice that the software is available completely free of charge and free of advertising, but only in English.

In games and graphics applications, f.lux can be responsible for a loss in the frame rate. In addition, you usually want to use the standard color rendering so that the representations look realistic. However, so that you can fully enjoy the graphics, you can set f.lux to deactivate itself automatically for certain applications. Operating systems such as Windows 10 now have their own night light mode. However, f.lux offers significantly more configuration options. We can highly recommend the software to you.
