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.

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.

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

The company's website suggests that you can change the position of the sun, presumably there's nothing preventing you from modifying it on a timer or slider.

Actually, the light is set at a certain angle and can't be changed [0]. They let you choose between different angles – 60º, 45º, and 30º (mounted on the wall). They say that they are working on allowing for light adjustment in the future [1].

(Not your fault though - their website is pretty sparse on information.)

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]

Somebody on reddit made a cheap do-it-yourself version for their basement office for $150 (using LED lights for plants): http://imgur.com/a/r31Gb 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: https://www.youtube.com/watch?v=-JVqRy0sWWY&t=3m40s Using 10 of t…

While this is is nice, the main breakthrough of CoeLux is the simulation of Rayleigh scattering, not just a bright diffused light.

And while fun to read, the cheap trick above doesn't have the right lightwaves to make you feel the same.

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.

LED bulbs started expensive as well. I just bought one for $1.97 (Cree 60w equiv) at Home Depot this evening. Manufacturing efficiencies take time.

That's an incredible price for a Cree. Is it a special sale?
