@pepe72 F.lux doesn't adjust the backlight brightness. It just adjusts the black level, which makes the overall color easier on the eyes, appearing darker while not actually being darker. So you need to adjust the actual brightness of your display, which is done with buttons on the monitor or on the laptop.
ooh :( In the future will it be possible to adjust the brightness? My problem is that I adjust the brightness of my monitor to the minimum, but it's not enough! it's still bright. F.lux helps me, and it would help me even more if I could lower the brightness too!
If you are setting your monitor's backlight to its lowest possible brightness, then there's absolutely nothing you can do to make the backlight any dimmer with software. The only possible option you have at that your monitor's lowest possible brightness is using something that increases the Black Level (which can also be described as reducing the White Point) which f.lux does when you tell f.lux to lower the brightness. It isn't capable of adjusting the backlight's brightness.
What is the warmest color temperature are you setting f.lux to? Maybe that's the problem. Try 800K.
I have a quick question regarding a topic that was brought up by the OP. The OP suggested certain functions for the f.lux program, and I'm curious to know if these functions will be included in future updates or if there are any community-driven solutions available.
If anyone has information regarding the development plans for f.lux or if there are any existing community solutions that address these functions, I would greatly appreciate your insights. It would be fantastic to know if there are any updates or alternative options to explore.
Thank you in advance for your time and assistance. I look forward to hearing from you.
@Tungsten_smooth yes, in a directional light, lumens=lux at 1 meter. In a hue bulb (600lm) it's radiating in all directions so it is somewhat less. If you want 10,000 lux you would have to be very close or have a dozen or more bulbs at arm's length. Not easy to do with this form factor.
Hue v1 maxes out its melanopic content in the mid-4000K range because it employs the most "chips" and the illuminance is somewhat higher as a result.
The tubes are likely more directional and would probably be better. Many ad-hoc lightboxes were built like this. But also there are reasonable light therapy panels online for $50 that will make this amount of light to, though some of them have to be used very close to the eye as well.
Don't forget to diffuse the light - staring at any of these lights directly for 30m can be quite painful.
Hi @maxime - no we do not agree it is wrong. It's there for a reason, which is that your body is made up of clocks that entrain to light. That's all it says and it's true.
It would be wrong to say it's a psychological trick or a thing that only involves sleep or a little suggestion, it's actually pretty fundamental to our biology and we want more people to know about it.
Here is a paper that explains how half the proteins in the body are rhythmic based on when your eyes see light - the truth is that your body has billions of clocks, and they're everywher. In some ways, you can choose to have them work well or not, by giving them a strong day-night signal. This is the way immunity, digestion, repair are regulated by the body, and why timing of light is so important.
@Barrydunn f.lux is still better than Night Light, but hey, you gotta do what you like the most right? That's what I'd do, so that's all I can recommend. F.lux or Night Light, whichever you like the most.
The current warms the filament while also producing light. A typical dimmer reduces the current, which generates a little less light, but does not stop the incandescent from working. The LED bulbs are working differently, they don't produce heat while consuming energy, only light. I am using only leds in my house, because they are much safer in my opinion, plus they consume less energy. With this smart bulb which I got from amazon, https://www.amazon.com/smart-light-bulb-bulbs-color/dp/B0922Q43LY/I can change the color however I want, and not worry about the light's warmth.
Hi - from a color perspective, on our PC build at least - you can do "use wider slider ranges" and get more "blue" than normal during the day.
I should mention that the way we do this is by removing green and red, and so while there is more blue in a relative sense, it is hard to increase it overall. So this might not work as well as seeing more actual blue skies. But you are welcome to try.
There are indeed visual opsins in the skin, but many of them do not have access to a chromophore, so they don't activate to a neural pathway like those in the eye. There are some potential links with subcutaneous fat in recent experiments, but only in albino mice, and there is no consensus on it yet.
