Somebody on reddit made a cheap do-it-yourself version for their basement office for $150 (using LED lights for plants):<a href="http://imgur.com/a/r31Gb" rel="nofollow">http://imgur.com/a/r31Gb</a>While definitely not the same, there should be an opportunity for something costing less than $35,000 while still getting closer.For example here is DIY 90,000 lumen flashlight that supposedly cost $250-350:<a href="https://www.youtube.com/watch?v=-JVqRy0sWWY&t=3m40s" rel="nofollow">https://www.youtube.com/watch?v=-JVqRy0sWWY&t=3m40s</a>Using 10 of these LED chips:<a href="http://www.ebay.com/itm/100W-Warm-White-3000K-LED-Light-High-Power-Component-Chip-100-Watt-8000-LM-USA-/281833108024" rel="nofollow">http://www.ebay.com/itm/100W-Warm-White-3000K-LED-Light-High...</a>

I'm looking up at my square white ceiling wondering what it would be like if the entire surface was this CoeLux panel. Imagine a vibrant blue sky with a beautiful sun tracking its way across your ceiling all day. I think it could be breathtaking.This is the type of 'simple' invention that you could never really anticipate but changes the future profoundly.

Sadly they write little substantial about the internal construction principle so I'm making an educated guess: Based on the pictures one can see that relatively hard shadows are created as expected by a point-like light source (like a far away sun). Also in the movie it can be seen that the 'sun' moves with the camera when the camera moves. The hard shadows would be created if all light emitting the 'window' are almost parallel, which would require some kind of optics. So I'm guessing that the 'skylight' is made of a slightly curved backside supporting a large number of white LEDs. Each LED then would have a small lense so that all light is emitted within a very narrow angle. The slight curvature of the backside would then lead to the apparent movement of the light-source if the camera moves. (Because one would look into the opening angle of a different portion of the LEDs) The blue color itself is a layer of nano-particles leading imitating Rayleigh scattering of the atmosphere.

Artificial sunlight could be revolutionary if applied with scale in cities. It could enable new, far denser forms of architecture "built for people", mitigating the ill psychological effects of being without natural surroundings.The energy use would be heavy, but it might be worth the cost given the transportation energy savings and higher productivity and happiness of the city population.

Wow. I was looking at the first couple photos thinking "I get it, that's what a skylight looks like, now show me the damn lightbulb!"Here's to hoping this tech gets commoditized and indoor spaces get a lot more pleasant.

The article is a year old. Does anyone know where the tech is actually at now?I was expecting this to be slightly more common by now.

67.000$ for a great looking light source seems too much. You can buy small houses at that price point where I live. With real windows, you know.

Coming soon to the office of a CEO near you.It's nice, but it's not $30,000 nice. Still, the cost of LEDs per lumen continues to drop. LED auto headlights are now below $100.There's a market for this in hospitals, to keep patients in intensive care units in sync with the outside world. Fake windows with lighting tied to the day/night cycle have been used. Here's someone looking for funding for a startup to do a really good virtual window.[1][1] <a href="http://windways.org/personal_page/virtual_windows/" rel="nofollow">http://windways.org/personal_page/virtual_windows/</a>

Here's a video of an actual one: <a href="https://www.youtube.com/watch?v=lD6VKLoS59g" rel="nofollow">https://www.youtube.com/watch?v=lD6VKLoS59g</a>It does look very realistic, but makes me wonder whether having an uneven light distribution is desirable or whether it's something that's needed to trick the body.

For those that work in office buildings and may be far away or do not have immediate access to Windows while working, would this be a good investment for companies to make?The sun availability does seem to affect my daily energy and motivation.

Bet the spectrum looks quite different to that of the sun. LEDs are narrow spectrum with peaks and dips, even when combined

In this video ( <a href="https://www.youtube.com/watch?v=aJ4TJ4-kkDw" rel="nofollow">https://www.youtube.com/watch?v=aJ4TJ4-kkDw</a> ) they talk about the usage for underground buildings. It could be for underground buildings what the lift is for high buildings (eg make it practical).This was on Product Hunt a while ago: <a href="https://www.producthunt.com/tech/coelux" rel="nofollow">https://www.producthunt.com/tech/coelux</a>

Not nearly the same, but Daniel Rybakken does lots of cool experiments with artificial sunlight that might interest you as well:<a href="http://danielrybakken.com/daylight_comes_sideways.html" rel="nofollow">http://danielrybakken.com/daylight_comes_sideways.html</a><a href="http://danielrybakken.com/daylight_entrance,_stockholm.html" rel="nofollow">http://danielrybakken.com/daylight_entrance,_stockholm.html</a>

Appears that the light is stationary, which to me seems like it'd be a bit creepy.

I'm photophobic and am guaranteed a migraine when in direct sunlight or high contrast lighting environments. Diffused, evenly lit indoor environments are my safe harbor without dark/polarized/full-cover sunglasses. Please don't take that from those of us that'd love outdoor lighting, but physically cannot tolerate it.

Now that's the kind of thing that would make Vault 101 more cheery! The survivors of the nuclear apocalipse would surely revere the inventor of this thing as a god....and obligatory musical reference: <a href="https://www.youtube.com/watch?v=txPqV0lZaSE" rel="nofollow">https://www.youtube.com/watch?v=txPqV0lZaSE</a>

I know it would be a tremendous waste of energy, but could you imagine spacecraft having a relaxation room like this?

It's be fun to have a tunable one that could simulate other atmospheres as well. There are days retiring to Saturn seems a good option ;-)With the added benefit you could use a low-power light for those distances.

If they can make a model i can hang on the wall (i really don't have the root space to mount this), i'm game.

Cool but creepy. How about just build non-gulag style buildings with exposure to actual sunlight?
