Yes, I read the same article. Do you believe, based on a single word, that the author believes that literally zero people in the entire course of human history have ever suggested “brighter lights” until Yudkowsky came along?

I don't know who any of these people are, but that is exactly what the article says, so why should we not believe that that's what the author believes?

Because it’s far more likely that the author chose slightly wrong words that ended up conflating a specific invention with being the first human “to invent the idea” that “hey, brighter lights would be closer to obviously brighter daylight” only 5 years ago. I’d wager that the author realizes that more than half of adults today had that insight sometime prior to 2017.

I always wanted to build a "periscope windows". Have a large light-gathering lens on the outside, then focus the rays into a much thiner "sun tunnel", bring them underground (in the same shaft as the water and heating pipes), then expand the rays into a fake window. If this was possible it would completely change the way we build homes, we could have many underground floors with "periscope windows" and a towers of li…

Not possible.

While Elizer certainly didn't invent the thing, just read the references he cites. He was right that its a pain in the ass to build and that pretty much all solutions available are no where near bright enough despite claiming otherwise. Expense and heat, which is really just more expense, aren't the only issues though. Assuming the premise that its good for health, another issue is that we do not know if the health e…

If I just like the daylight-bright lights, I don’t need a research paper to tell me that. I would buy many of these for several hundred £ if I lived in cloudy London again.

Quite tangential, but I always giggle at this version of time-is-money "I have already put 6+ hours into researching this idea; I would probably pay at least $400 to get that time back."

I understand the reasoning behind adopting such frames, but for me, this way of thinking wouldn't work at all. At best, it'd be my new procrastination shiney. I find a lot of benefit, and also quite enjoy, quantifying like this at a bigger scale, but micro-rationalising such as this totally doesn't suit my brain. I wonder if it's me or him in the minority?

The "therefore" following from the time-is-money logic (he would pay > $1000 for this product) seems like a pretty alien disconnect for me. My back of envelope would probably be "most people pay between $x-$y for lighting and/or other decor stuff, therefore..." s

I don't disagree on his conclusion (maybe $400-$1200 price point), which makes me wonder if either of us are really arriving at our conclusions in the way we think we are, or just retconning our reasoning using random ideas floating around our minds uselessly.

In any case, I think the overall idea is good and the timing is good. For a start, it's a fairly DIY-ish on the interior design front thing regardless of available products because you can't use 20000 lumen lights the way you would a 200 lumen light.

DIY Perks [1] has a good tutorial on how to make a super bright LED panel from LED strips. Quite easily, actually. Been using one of those in my office for the last eight years or so. I use a server PSU for power. I was surprised to see how bright it is when I once went outside while it was on. Not only was my window the brightest in the entire street by far. But it actually illuminated the trees around my window. If…

I was going to suggest diy perks but thought you were going to link his artificial sun video [1]. I’ve been wanting to build one but not sure where I could fit since it requires a bit more space then a bright led build would. https://m.youtube.com/watch?v=6bqBsHSwPgw

I wonder what one gains by using super bright lights. The pupil will adjust to counter the effects of lighting. Adding more lux just makes your pupil smaller. Or am I missing something? Maybe its non linear? Or maybe the idea is to reach the minimal pupil diameter? Or maybe happiness is somehow dependent on pupil diameter?

My guess is it's some complex neurological response triggered by 'knowing' (or being sufficiently convinced) that one is surrounded by bright outdoor sunlight, rather than a physiological response powered by the light absorbed by the retina. What matters is the brain's estimate of the current lux value, which would take pupil size into account. This is just a guess.

Not only that, but it would also be impossible to see what’s on your computer screen as this isn’t designed to outshine the sun.

if such a thing were possible, would it be healthy to use a monitor with a 10K lux backlight? I can't decide if this would help or just fry your eyes.

Perhaps in theory, considering that when you look at someone's face outside on a sunny day, it is brighter than that. OTOH, staring directly into a lightbulb isn't pleasant, so I suppose there's more to this.

Either way, I think the best way to deal with bright light isn't a brighter screen. It's an unlit screen, like e-ink or something.

In many cases (mine included), SAD is not so much about how much light we get, but about when: I manage my sleep/wake cycle by getting a good dose of light in the morning (I do my morning E-mails with a nice strong blueish LED-lamp next to my monitor) and dimming/reddening my screens in the evening.

It is not even the level of darkness outside, but the direction of the level change: I need my lamp from October to January (or when I have a gig in Norway in the winter) but already at the start of February I feel the light coming back, even though it is as dark outside as at the end of November

So, in summary: it is more about the timing of the light than the amount (but YMMV, of course)

I'm from India. Lighting in my middle class house, since forever, has been poor. I never consciously felt it when I was still studying. Just that the rooms were dark and I would prefer to play/study outside, or in the front room, where the door was always open, allowing a lot of sunlight. I realized the lighting factor a few years back. Now, My own home has two lights in every room and whenever I am studying/reading/…

> The difference is stark.

For led lighting, 20W (ceiling fittings) for every 100 sf in rooms with light walls provides a lot of illumination in my experience. Can double that for kitchens etc.

For a year I had my home office setup with LED strip lights all the way around the room. They were mounted on a narrow shelf encircling three walls. Color temp was about 6000K.

I loved it, for a while. It felt like a fresh bright day. However, after some months of 12 hours a day of working in this environment, I started having pain in my eyes, almost as if they were being squeezed.

This discomfort persisted for a month after I left my office (took a DN work-cation in the Caribbean). As I began looking into this, I started reading about issues with blue light. I found suggestions that too much blue light was harmful. And likely me spending 12+ hours looking at bright monitor screens was also harmful.

After returning from my trip, I removed most of my lights and turned my monitor brightness way down. Since then, I haven't had the same bad feelings.

I would think that light is light, and only brightness and color temperature would be the variables. But perhaps there's something more, because in general it seems that eyes are fine with outside daylight but less fine with indoor lights. I would like to know what is best for my comfort and health, but I'm not sure anyone really knows; studies and articles often disagree...
