f.lux vs. Night Shift in macOS 10.12.4
-
@herf when you are comparing to Night Shift, are you using the default mode? How much blue light does it remove if you put it on the warmest setting?
-
@cjmegatron81 The full dataset is here for iPad Pro:
https://fluxometer.com/rainbow/#!id=iPad Pro Night Shift/defaultThe Night Shift UI implies that the defaults will help you sleep better, which I disagree with. To be specific, their defaults remove <30% of the impact blue light has on your body. (Your body wants a "dark signal" not a "slightly less bright" signal.) Also, in software we know that a huge majority of people stick with the default settings.
The strongest settings do appear to be better. However, the Mac version is also brightening the screen on the warmer settings (which cancels out most of the benefit), so the iPad data are somewhat better than the Mac. We'll post data when we've updated a newer machine.

@herf is it possible for me to run tests on my machine to find out myself? I have a late 2015 iMac.

@cjmegatron81 We have a way to do this coming up very soon. Most of the f.luxometer measurements are done on a Photo Research PR-655 Spectra Scan, you can see the current project at https://fluxometer.com/rainbow/

@lorna thanks!

I have compared Night Shift with f-lux for the past couple of days, or should I say evenings and nights, and I do not hesitate to say that f.lux is much better than Night Shift. So, I happily donated another 5$ this year. Keep up the good work!
-
Very nice comparison. Are you guys planing to compare the night mode in Windows 10 with f.lux?
-
@AlixSPQR Thank you for your kind words and your support, it means a lot.
-
@meinmoises Yes, we post all new data at the f.luxometer project: https://fluxometer.com/rainbow

@lorna You're welcome! :slight_smile:

One (and the only one) thing that Night Shift as of now does better is that there is no white areas color corruption on fullscreen YouTube videos.

People are reporting that it works in f.lux too since they fixed the bugs we reported to them... Love to know more about your system if it's working in one and not the other.

@lorna sorry, I might have old information because since latest macOS update I have never actually watched a YouTube video in fullscreen with f.lux enabled.
Did a quick test right now, no issues so far, woo-hoo! -
@herf Could you please include some axis titles on your color charts? What do the grey areas signify? Is uW, Micro watts? I take it the colors shown are what are displayed on the screen, not what colors are being blocked.
What do you use to output the graph? I'm curious enough to do some tweaking on my own screen.

More info is at https://fluxometer.com/rainbow/
The screenshots do show scale as uW/cm^2/nm (spectral irradiance) in the top corner, but for spiky spectra that is not the most useful number.
We might be more interested in the total irradiance for each photoreceptor, which you can find in the "non-visual" tab on our site. It shows the "equivalent illuminant E" irradiance, as well as total power.
Our models and sources are on the pages too.
