Comment on CoeLux: Artificial Sunlight That’s Real Enough to Trick Your Camera and Brainparent

It’s also a 660-pound object installed in a drop ceiling nearly a meter thick. You’d need very high ceilings to start with, and you’d better hope it’s installed well. Not to mention that it consumes up to 300W of power.

Well sunlight is around 1kW per square meter energy density, so it doesn't surprise me in the least that this takes .3kW to simulate sunlight.

I wonder if they could glue their magic scattering pane to a mirror and lit it with a lamp from underneath (from inside the room that's being lit.

... or even make el cheapo version with just bluish tinted mirror.
