We have some data posted here, so I think you'll find that gunnar removes about 1/4 the melanopic light, similar to running f.lux at 5000K:

We recommend much stronger settings that remove 90% of the light at night.

You should definitely dim your display as much as you can.

f.lux helps adjust the display on a consistent timeline and keeps things bright enough to read, but dimming has a large effect.

Yes we should expose that as a separate parameter.

We designed this to handle lighting your "whole house" and not just the lamp near a screen, so if you have a bunch of people living together, they usually don't want to have the lights change because one person disables f.lux :)

Hi,

Night Light was better in the 1809 version, before and after that it's just unreliable.

The desktop uses RGB only, not YCbCr.

f.lux loads the current ICM profile, not any NVIDIA control panel settings. If you want to calibrate a display so all apps can use it, you should use something that makes an ICM file.

Update: I have to admit, it works perfect for my needs!

OK, it seems that flux is now holding control over the brightness instead of windows. I had to enable the F9 through F12 option in the screenshot below, because alt+pgUp etc.. was not working for me.
Now I can control the brightness with alt + F11 and alt + F12.

Hope that helps 0_1564779524135_8ae338b8-485b-4c40-a8e9-f08e94c06ade-image.png

@neil8507 please post your driver info. f.lux options > driver info

@lilyofthevalley no, f.lux is very good at loading spyder profiles. You just shouldn't have two programs doing the same thing.

same problem, I like to use f.lux with pleasure but lately I have apparently done something wrong.
The image dims as I want, but when I open a new page, I have a white image again which dims after a while.
What should I set to prevent that and it just dims in the evening and stays dimmed?
Macbook pro 15" mac OS 15.14.5 .

Fantastic, that did the trick. Thank you!
