So this would be less than 100 dollars for approx 40000 lumen, with all in one enclosure including head sink, can be wired to mains or wall socket. Also with this design they can be angled.
Not adjustable in brightness or colour temperature, but my preference would be overhead lighting for day, and then incandescent side lamps after dark (a sun above vs. fire).
But more like 300W instead of 28W. So taking the enclosure and remote control of the bathroom type light, with the LED setup of a floodlight.
As for CRI, I guess it would be bad. How important is CRI though? Does this relate to subjective sense of “harshness”?
The best solution I could find was LED security flood lights, e.g.

In terms of consumer product, I think something like this might be ideal:

I also found this: https://nofilmschool.com/diy-light-panel-busted-lcd-tv
Stresses importance of size, diffusion pads and fresnel lens for creating a soft, diffuse light.
Was thinking a good DIY project would be to take a LED floodlight and wire in behind a busted 50″ display as a side panel (artificial window).
So the ideal consumer product might need to have a pretty wide surface area and fresnel lens which would drive up costs.
