Photographers often need to build an artificial window or create artificial sunlight. Here's a fairly good tutorial on how to do that using a used satellite dish:

Personally I have affixed studio lights to my home office walls, with umbrellas, for Zoom calls (total cost < $200). I find that they also enhance my mood / energy levels, so I switch them on whenever I need to boost my spirit or productivity.

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…

Since the OP is quite courageous about claiming someone "inventing" this in 2017, I'd like to highlight your prior art: > Been using one of those in my office for the last eight years or so. I use a server PSU for power. And as you mention, articles on it have been circulating for even longer.

It's Yudkowsky from LessWrong, he is actually a quite insightful thinker, but his disciples claim stuff like this all the time. LessWrong is an extreme echo chamber.

For me the breaking point was Roko's Basilisk, a self-proclaimed "most-dangerous idea of our time".

> Someone should probably start a bright home lighting company Such a thing already exists. Its called a lighting design company. People need to admit that lighting (like cryptography) is hard, and that if you're serious about "doing it right" you need to bring in a suitably skilled professional. Each house/apartment is different and every room within it is different, you'll never be able to magically buy good lighti…

People already spend thousands of dollars on skylights without any professional lighting design, yet they pay a professional draughtsman to design it specially for their house, council to approve it, and licensed tradesman to build it. I don't get why they don't spend those same thousands on what you suggest or an off-the-shelf product that an electrician (or DIY) can install.

"Natural light" is one of the motivating reasons for open-plan offices, so practical artificial windows could help reverse that trend.

I struggle to believe that this is the case. Many offices are massive single rooms in buildings with large floor plates and often meeting rooms may end up placed around the edge. So in practice I think big open offices (and the desire to have everyone close in one room) tend to lead towards not getting much natural light, but of course if you put smaller offices or cubicles in that space they’d get even less light.

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.

Well the sun makes 50klux of light on the surface, and we look at that amount all the time with no harm.

I tried doing something like this last year, I purchased lots of 1000 lumen LED bulbs. The light was blindingly bright to look at and it looks very strange in a room. My takeaway was: * that you need some type of diffuser. * The light leak out of the apartment was crazy. My apartment looked completely insane from the street. * The light warmth is very important. And proper sun coloured lamps don't exist or are crazy…

"Warmth" and "naturalness" are produced by high CRI index (90+).

I have 8 lamps with CRI 90+ in my living room, at 5000K color temperature, 1500 lumens each. They produce nice light that seamlessly mixes with daytime sunlight from the window: they seem to have the same color.

I also have a few LED strip installation over desks and tables, very bright at max dimmer setting. A diffuser is a must, even though it lowers the brightness noticeably. Without it, anything moderately shiny will reflect painfully bright dots of light.

Yes, but usually we don't look into that.

This has been applied for decades. Those 'ceiling windows' in art galleries are often false windows with bright daylight lamps beneath it. By the way, the sun produces ~50.000 lux on earth's surface. That's 100 times more than in a wall illuminated office. To reach that brightness, you would need tens of kilowatts of LED lightning for medium and larger sized rooms. That's totally infeasible. Also, imagine the heat bu…

Many people (including myself) find such brightness levels uncomfortable, and wear sunglasses.

Sunlight is free, but electric light is not. This is why light in my apartment is very bright but not nearly as bright as the streets on a sunny summer day.

If you have Hue lights, make sure to upgrade to the new generation that just came out. It's much brighter. The color ones were sold out, but I found it worthwhile to upgrade even though I can't make them blue anymore. Otherwise, Cree is one of the best home bulb brands.

Funny thing about Hue, instead of brighter, I wish they'd go dimmer. If I want more light, I can always get more bulbs. But currently the lowest brightness (at least for the standard white tones bulbs I have) is too bright to work for evening / night scenes.
