I usually eschew labels, preferring simply "sleep weirdo", but I fit the pattern of "Non-24 Sleep-Wake Disorder", with my sleep and waking times drifting progressively later at semi-regular intervals. The result is that I'm often awake through the night. (This week I'm going to bed around 9:00 a.m.) Even with that, I've noticed some pretty big productivity swings based on the season. Interestingly, this hit me very h…

>I tend towards 400-500 watt halogen bulbs.

Are those really 400-500 watt or just give light equivalent to 400-500 watts worth of incandescent light bulbs?

Is there any solid peer-reviewed, published papers on this stuff? While it sounds intuitively correct and attractive, I've struggled to find anything rigorous that shows light colour and intensity in the evening has an effect of sleep quality - its all anecdotal.

Second this, and I wonder how people who live near the equator respond to seasons and light vs. people closer to the Arctic circle.

Very much this.

I live in Norway. While I'm below the Arctic circle, summer nights are bright. I don't need outdoor lighting to read as the sun goes juuuust below the horizon. This time of year, days are short and the light intensity never really gets all that bright. I don't have issues with any of it - and I'm an immigrant.

Because I am more productive when it is dark or overcast. I get nothing done when it's bright.

I struggle to focus during the day and become more productive when it is dark.

That's interesting since I too can only really focus at night or late evening. I knew someone with ADHD and I could see some glimpses of me in their behaviour.

I put a bulb like this only in my office. Has helped tremendously although you notice the difference in light color between it and the other lights in the house right away.

I absolutely hate LEDs. I don't know why, but I just hate them. Especially the white ones. The yellower are similar to a mid summer day and I can cope with them, but there's always this feeling of something being off. I guess it's connected to us humans being used to non-sun light being (similar to) a fire - mainly consisting of yellow/orange tones. Also, I don't exactly remember from where I read this, but when a (t…

My experience is that daylight-blue (5000K–6500K) LEDs or fluorescents feel unnatural unless they are quite bright; something in the animal part of my brain worries that the sun is broken. Low CRI bulbs also feel off, which makes intuitive sense I suppose. I've found that high CRI warm white (2700K) bulbs are the way to go for me. I have these at home, and I like them a lot: https://www.lowes.com/pd/GE-Relax-60-Watt-…

You need more that 60 watt.

I'm most pleased with the page's non-Javascript based image comparison slider. Nice one.

It didn’t work for me on mobile, and only in a weirdly rendered way on tablet. I would have liked it if there were just plain image links available.

(Michael from f.lux): this kind of thing is necessary for most buildings, because otherwise people don't get a "day" signal when they spend time indoors. Most of us spend >90% of our time inside. However, we shouldn't mess with light levels like these (or even somewhat lower ones) without some limits, and the main one is some automatic timing to turn things down after it gets too late. Otherwise you will find yoursel…

I love f.lux and I've used it for years, however I have to bring up the one feature I dislike...the "alarm clock" type feature which supposedly could be turned off by an option, but in reality there was no option to turn it off. I was able to turn it off on one computer but not the other, both windows OS!

Not sure if it generalizes. And if it does, not sure if it does do all ADDs:

I'm ADHD without the Hyperactive component, subclinical, ADD or (ADHD-PI or Inattentive-ADHD more precisely). Or with the H component purely mental/internal, which kind of sucks because you get the "benefits" of ADHD plus a higher propensity to slide into an unhealthy ultra-sedentary lifestyle.

Same experience here. I film all the led bulbs I purchase in 240fps to see if they flicker at 60Hz. I discovered that Philips bulbs NEVER flicker. Occasionally I stumble upon other cheaper brands that don't flicker, but there is never any guarantee. I might buy 2 batches 6 months apart of bulbs from the same model from the same third party seller on Amazon, and they slightly changed the product (updated packaging and…

A ton of LEDs flicker at 120hz which makes me crazy. It's like a strobe effect that I only see when moving.

The Edison style are often like that. They use four led elements configured as a full wave bridge rectifier but because the diodes are themelves the load ther is no place to put the lowpass and so you get 120.
