In the history of LED lighting, it took quite a bit of work (hybrid phosphor technology, etc) to get them to emit warm color temperatures. The exact color temp can be a personal preference, but I think a lot of people aren't privy to the difference the color temperature of "white" light can make! I want to go on a guerrilla campaign around my neighborhood and replace porch light bulbs with warm equivalents.

While the color temperature situation has improved, the actual spectral quality of most consumer LED lighting still leaves a lot to be desired. CRI makes an effort to measure this, although it's a low-granularity measurement. I personally buy surplus cinema lighting equipment and use it to light my house. I have a bunch of fancy cinematic LEDs with high CRIs that produce decent light, although they still can't fully…

using surplus cinema lighting equipment is genius.

A big thing not often spoken about with eye strain is dry eye caused by the lack of blinking due to focusing on screens too close to our face. This is an evolutionary phenomenon--close dangers cause extreme focus without blinking. Extreme focus on close items reduces our blinks. Our eye lids have glands in them that release oils on your eye with each blink. These oils help prevent the watery part of your tears from e…

I, too, experienced dry eyes and found it challenging to consciously blink regularly. A few years ago, someone gifted me one of these "3-D puzzles" (similar to this: https://www.amazon.ca/Bookend-Miniature-Bookshelf-Birthday-B...). I kept it on my desk and it helped me somewhat regulate my constant focus on the screen by prompting me to glance at it occasionally. That's just something that worked for me.

I'm not aware of any triggers to cause subconscious blinking. That'd be fantastic if there was an option though. The web app can trigger a notification if your blinks / minute drop too low. Only challenge is modern browsers throttle websites that aren't visible, so the blink counting gets messed up.

Maybe you could set up the conditions for a Pavlovian response. E.g. let your app give a signal (e.g. beep or buzz) every 30 seconds if you don't blink. Then train yourself to blink if you hear the signal. Edit: Yes, it can be done: https://en.wikipedia.org/wiki/Eyeblink_conditioning

You could also lie less often, because you blink less frequently when you lie. ;)

> When it comes to light brightness, too much is just as problematic as too little Recently moved into a house with on/off light switches. Having the ceiling lights on full brightness was downright oppressive. I installed dimmer switches, and it's so much nicer it's hard to really convey.

How do you source lightbulbs? I have yet to find a reliable LED bulb that doesn't hum or flicker on a dimmer despite being advertised as "dimmable" . . .

Philips Ultra-Definition 60w equivalent bulbs are amazing and really reasonably priced. They also work really well with standard dimmers with extremely low flicker.

Would love to know how did you generate those renderings? Is it blender or something else?

It’s adobe substance stager 3d

Oh, it's CGI? I wanted to know who your housecleaner was and if I could borrow them. ;) So much cat hair...

Having worked from home for many years, I was surprised that I had never come across the acronym “WFH” before. It took me a moment to decipher its meaning, especially since the article introduced another acronym, “PWM” (pulse-width modulation), right at the start.

Have you heard of COVID? Is your home the ISS or something?

Now you need to tell him also what ISS is

Talk to me about color therapy

Nature bathing is great. But it turns out that people in hospital beds facing windows recover faster when they face nature. And, in fact, it's not the nature at all! It can be fake and just as effective. In the end, basically, it's the green. Color therapy or chromotherapy is incorporating specific colors into your environment to evoke desired emotional states. It blows my mind how well this works, and that's why you…

How do you accomplish silver colored lighting?

> An even, diffused lighting environment is best for the eyes indeed. i am unsure where the love for those "spotlights" embedded into the ceiling comes from. every time i enter a room that has them i want to crouch like gollum. the only thing they seem to do is blind you. indirect lights can be expensive and hard to find though. i built 12 hanging lamps that illuminate the ceiling instead of the floor myself, which s…

Doing it with hanging lamps is a clever solution. Doing it indirectly is the goal. There's one company out of the UK making super high end LED diffusers that can be precisely controlled - both the amount of light and the direction. Can't remember the company but it was similar to this: https://www.acalbfi.com/technologies/photonics/optical-compo...

A lot of the guidelines that are used to light a scene for a camera are also quite useful for lighting a room for yourself, just with less light needed as the human eye has a much higher dynamic range than a camera sensor: * Use diffuse light. This usually means multiple light sources bouncing and diffusing light off surfaces (ceilings, walls, etc) or diffusers. * Minimize shadows. Shadows lead to contrast which can…

I agree up until golden hour. It's a very specific style of lighting and isn't any better or worse. It's not the best time to take a picture, it doesn't have the best light. It's a specific kind of light.
