But I don't want my office to be as bright as the outdoors. I want it to be dark.

I’m the same. It is very interesting how people have radically different experiences with light. I feel the best in winter with cloudy dark days. My wife is completely opposite and so are most people it seems, they feel good in sunlight. I’m afraid of it and the summer heat.

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 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…

Possibly due to the lights being driven from AC power making them pulse. You gotta find ones with big enough caps that they don't flicker, or buy some grow LEDs and a decent DC driver to emulate the sun.

I have an LED build-out that was inspired by the Lumenator (https://arbital.com/p/lumenators/). Since that post 1600 lumen A19 bulbs have gotten much cheaper and so I run 9 of those in a 3-fixture tree lamp with 4-way spliters.

I also experimented with commercial string lights and ended up hanging one strand with around a dozen bulbs over an ikea pyramid coat rack behind a Japanese style paper screen and that made for a bright and beautiful standing lamp.

I also found that having a timer/dimmer was a great way to wake up in the morning. Much better than any alarm, but if you don't sleep alone you need to get your partner on board.

I highly recommend trying a build for yourself!

> I fit the pattern of "Non-24 Sleep-Wake Disorder", with my sleep and waking times drifting progressively later at semi-regular intervals. This is a disorder now? I thought that's just how humans worked. It's how I work, anyway - if nothing else (like work, or children waking up at 5:30am) forces me to get up at a set time, I'll slowly cycle through until I'm going to bed at sun-up and waking up at 3pm.

No this isn’t typical. Are you particulary good at coping with jetlag?

> isn't this expensive to run comparing lighting to the consumption of a fridge, which is one of the most energy intensive appliances in an average house, is kinda ridiculous. Its like saying your lawn mower energy use is just fine because it consumes the same as your SUV. Tl;dr: 2kwh per day for a light is a LOT. A standard led light would consume about 5% of that.

Three incandescent light bulbs that would have been standard 10 years ago would consume as much energy while putting out far less light. It's not a crazy amount of energy, standard LED lights just use so little energy that it's hardly worth measuring.

It can't be much worse than being under the blue sky.

The blue sky's spectrum doesn't have a giant spike like this: https://www.benkuhn.net/img/lux/ledspec.png

Yes it does! A giant spike in the blue region is literally what makes the sky blue in the first place. If there weren't such a spike the sky would be white. When you look up at the sky on a typical clear day, you're getting more blue light than almost any one of these indoor setups.

this comment makes no sense. even assuming these things are equal, no one is just out there staring at the sky for hours on end for the small percentage of time the sky is actually blue.

So when you're at the beach, hiking, or driving on the highway, what are you looking at instead? The blue sky is going to be most of your field of view unless you just stare at the ground.

I have a one-person office with glass walls in a coworking space. I've been looking for a lighting option that could possibly go above or below my monitor. I like the bulbs in this article, but I would prefer something directional so that I don't disturb my neighbors. Any suggestions?

I'm not quite following - which direction do you want the light to shine?

I've got bias light setups at both my home and office with bulbs behind my monitor shining at the wall.

When it gets dark by 3:30pm and there’s so much cloud cover it never gets past dusk, you’ll appreciate the crutches. Biggest downside to living in seattle atm.

Ugh yeah I wanted to kill myself more and more every year I spent in Seattle. Moved somewhere sunnier and that urge just vanished .

Yup. Half my life is now managing that problem. I’ve gotten better at it but I really do need to move somewhere sunnier, especially for the winter.

> But as of recently, it’s totally practical to fill your entire house with light that’s as bright as full daylight.

If you actually get your house as bright as sunlight, that means you have ~1kW / m2 of light in your house, which is impractical no matter how cheap and efficient LEDs get.
