Any comments on meters you've liked?

I've got v2 color bulbs and a lightstrip. I thought I might as well get as close to zero melanopic light as possible at night. Any blue in the spectrum isn't helping at night. During the day the Raspberry pi program cranks it back up to white. (I'm on mac by the way, so i use flux for the screen but not for controlling the Hue lights.)

Currently I just look at the light through the cheap spectrograph and use the hue app to move around the orange color range. There's actually some surprisingly large amounts of blue in some orange looking areas, but it's hard to be precise with the simple spectrograph I have.

@herf said in f.lux and wallpaper:

You can just make your wallpaper darker all the time - it doesn't have to be a particular color as long as it's dark.

It is on our list to do something like this automatically, but we would have to figure out what images to put there - currently our download is <1MB so it would be expensive to send out 4k images in comparison. :)

What he's asking for is if you can find a way to make f.lux only affect his existing wallpaper instead of affecting Windows globally. He's not asking for you to make new wallpapers.

If you're on any of the recent versions, there is a "wake time" setting, and for this schedule we recommend that you set it about halfway through your sleep time.

So if you tell f.lux you wake at 10AM or 11AM it should do about the right thing.

We don't have any support for ChomeOS yet.

@neweye said in Blue Light Screen Blocker:

excuse me, but f. lux on my monitor philips 221el eliminate the problem blue ligh? I select 1200k...... I haven't the glasses

I think about 99.99% of the people on this planet don't need anything other than f.lux on any monitor. 1200K is more than good enough.

I would love to see an option for set to sunset settings for an hour rather than just disable. Sometimes I need something slightly less dim that really late settings, but I don't want to go all the way back to normal. I can do it manually, but it would be nice to have an easy drop down selection.

Ok, it looks quite useful. But I don't know exactly how to make sense of the data to compare the performance of the different filters.

Specifically, when I select a filter, a button appears called "Analyze filter". If I click on that a new graph appears and there is a tab called "Compare" below the graph. Apparently this is where data on each filter can be tabulated for comparison. I've figured out how to tabulate the data for the various filters, but I don't know what the data means. Is there some instructions somewhere explaining what "CCT", "Cyanopic", "Melanopic" etc. mean. And which data is most relevant for comparing the filter performance?

Ultimately, I want to get sleep glasses and a screen filter for my iPhone which I will use in the evening in my apartment. So I want to compare the performance of the filters for these applications.

I am interested in Hue Go, but not sure if it is helpful for sleep

It seems to me the answer is a big 'yes': https://classic.startpage.com/do/search?q=night+light+with+aromatic+essential+oils

@herf Thanks, that really helps. So, bright light will still have it's normal effect, along with this "extra effect" after dim light, so you still say dim light before that, will be better if the times aren't predictable. I'm glad I won't think too much into this effect now, but I'm glad it's on your research page.

I'm good on the dim bathroom light, I have two I can choose from, and one gets extremely hand burning hot (I have to turn it into the socket each time) using 20 watts, and the other no where near that level of heat using 24.5 watts. I like the dimmer more orange looking light, but wow it hurts! It's more orange, the other is a gold yellow and I don't like it as much.

All the best for the Tests :)

@OpticalDesigner many tens of
thousands of f.lux users have written in already - instead of allowing it, they released Night Shift, which is really not effective enough - it's not as strong an intervention and it only works on new machines with bigger and brighter screens. Oops.

We would love it if people keep writing in and saying they'd like to see Apple allow real f.lux for iOS. Thank you!
