Why f.lux changes color temperature set then I adjust it?
f.lux changes color temperature

This happens when you've used Alt+Page Down to artificially reduce the brightness.

This can also happen automatically on a laptop if you have f.lux set to go warmer at the same time when you lower your laptop's brightness. You can find this setting by opening the f.lux menu and choosing "Extras...".

Okay, cool. Thanks. :)

@harrydry You'll want to try changing the gamma levels, maybe that helps.

how much should i put the brightness

Do you mean the color temperature?

@rsoler Wow, I thought the trend would be higher color temperatures. Shit. I understand the want for lower colors, but why not swap back to those in the later hours, and keep bright white during the day? I've thought that would be the best way to go. Most fixtures have 3-4 lights, so have 2 for daytime and one, or the remaining for warm white, without as much cyan or blue spike.

@Astara thanks! I'll see if I can change that setting.

Thanks! This is really hardcore stuff for a mere mortal programmer ;-)

Working towards my own lamp, one research paper at a time (https://forum.justgetflux.com/topic/2850/rgbw-led-strips-f-lux-and-open-source)

Kelvin. It's a unit of measurement for temperature. For f.lux, it refers to the color temperature. Lower Kelvin values are "warmer" because they have less blue.

@Tungsten_smooth If the lamps you are looking for are in this database, download the data and graph them in your favorite spreadsheet? http://galileo.graphycs.cegepsherbrooke.qc.ca/app/en/home

Can you please include Hoya bluecontrol lens in your filter tests of fluxometer to be more accurate and scientific?

It doesn't make the color temperature warmer, it just reduces the brightness which means less light which means less red, green and blue light.

Oh! I didn't think about the input voltage.

For me, my thing is, when you want to know something, ask an internet search engine like I did.

@lorna No I didn't grow up with anyone using halogens, it was only incandescent in the 90s and it still is except for lower power halogens (28 watt with soft coatings) and fluorescents. I'm going to get the warm 43 watts to use, I can't wrap my mind around these lights.

Is it possible to set my own default settings on f.lux (e.g have Dark room mode activated everytime is run F.lux without having to go to settings all the time)

No, not with this current version. Perhaps with a future version? I don't know.

For future reference, "f.luxometer" is not the correct forum for questions like this. You should have used one of the appropriate f.lux support forums.

@jennlerner Try opening the activity monitor, and looking for "flux" there. If you find it, close it, and reboot the computer. Does that fix the issue?
