Overview

What is F.lux?

F.lux : Pf.

In depth

A closer look at F.lux

Pf. Llux is a small app that adjusts your screen color to the amount of light you are in. Pf. Lux uses the type of light in the room you are in and the time of the day as points of reference. If you want to get greater precision you can use halogen fluorescent or natural light. For your geographical setting and time zone the program requires your coordinates which you can find using the set your location function. This takes you to a webpage where you can confirm where you're from.

finally, just indicate if you want a fast (20 seconds) or a slow (60 seconds) transition between the color tones used on the screen.
