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…

>* Select your color temperature based on needs and feeling. A lot of people prefer warmer color temperature lights and cool temperature lights are known to be more stressful for folks with anxiety-related conditions, but if your work requires accurate color representation, or you find yourself mentally trying to compensate for color temperature, then change the temperature to what you find most productive yet relaxing.

This is huge. I personally can not stand warm color temperatures in my office or bedroom, I know all the colors are off and it aggravates me to no end. On the other hand, I can't stand cool color temperatures in the dining room because it doesn't lend well to eating comfortably. And in either case, I can't stand warm color temperatures on any monitors/screens or televisions because of the same reason as when I'm in my office or bedroom.

Use color temperatures that suit your preferences, going against them just because someone says it's better for you (eg: red shift at night, aka blue light fearmongering) is patented bullshit.

85" @ 1.5m is insanely big for me, do you not get sore having to dart your eyes about to read the corners?

> do you not get sore having to dart your eyes about to read the corners? I wouldn't be surprised if this is what makes it healthier. Not only are you exercising your eyes, you're also giving them a chance to let you know when they need a break.

Yep, I set my mouse sensitivity to extremely low as well so that I’m basically “wiping the windshield” of my desk while using my computer

I'm in a basement and had fairly good success with certain "led shop lights" to make the space feel more like it has natural light (though I could improve things further). I do find however, that using diffuse lighting and minimizing shadows is what makes lighting feel artificial. Natural sunlight has very parallel rays that create very evenly lit surfaces with very sharp shadows. Whereas most artificial light has ra…

What I'm trying to achieve is lighting a bit like in these "Artificial Skylight" concepts: https://architizer.com/blog/practice/materials/let-there-be-... They claim their technology is about "Rayleigh scattering" but I think that's mostly marketing mumbo jumbo. Sure that might add a bit of diffuse blue but their main secret, I would bet, is parallel rays which explains why their fixtures require so much space above the ceiling to get around conservation of etendue. The effect of parallel rays and sharp shadows are definitely represented in their example pictures.

They claim to know a lot but then none of them build proper Cf Lumen or F.Lux style tooling (i.e. super easy default instead of requiring tons of setup) for turning ALL blue light off (red shifting) IN THE DEFAULT OS as the primary way to use your device at night. None of that wussy shifting the color temperature brown shit that doesn't meaningfully reduce blue light hazard. I can literally preserve my whole night vi…

Probably not what you are aiming for but for Linux this is a somewhat solved problems. The default DM, Gnome, has built-in color shift with a time schedu…

Can confirm https://github.com/jonls/redshift works great; been using it for years.

How did you go about that? Can you just take your prescription someplace and have them made?

Not OP but look into "computer glasses". Usually they're optimized for distances a bit closer than 1.5 meters, but I'm sure that can be changed.

The magic words I think are “occupational multifocals”, which have a small area at the top for distance vision and the remaining 75% set for whatever your occupation is. You need to be very specific on the distance setting

How do you accomplish silver colored lighting?

I would guess by reflecting light off something silvery, eg, a wall painted in metallic silver paint.

That's not how colored light actually works. (That's the joke!)

There isn't a silver "color" of light, it's a visual phenomenon that warps and reflects the color of the environment around it.

So unfortunately there are no silver colored light bulbs (except for using a silver coating to block or reflect the light).

Maybe it's that shiny reflective things like disco balls are therapeutic, imparting modernity, sophistication, intuition, reflection, coldness, or disco fever.

I am quite sensitive to glare. I have tried many setups in my windowless office with low ceiling height and have found linear up-down pendant lights the best option. Up-light is more important as it bounces soft light from ceiling. When I want to work in dimmer environment in the evenings, I switch off the down-light. I also try to buy lightning fixtures that are designed anti-glare although they are more expensive.…

Glasses are extremely affordable online (e.g. eyebuydirect, owned by the same multi-billion dollar company that sells lenses and frames to local opticians) if you have the prescription, PD (pupil distance) and physical frame measurements of your current glasses.

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.

I just went through this with my car. All the OEM overhead interior lights were horrible 6000k+ type bulbs that not only made the interior feel like a hospital room but completely ruined my night vision turning me into the classic “Jesus!! You’re going to kill someone!” dad whenever my kids would fiddle with them at night. I cannot overstate how much of a difference it made switching them all to 3000k warm whites. Of…

Well done! How did you figure out 3000K replacement part numbers for each SMD?
