The dark is required, so many are all but blacked out. But I'm not sure on 100% artificial. I do know it's completely over reasearched.

Coops are now one of the most crazy over-specified engineering things you'll ever see. They test and maximize cost efficiency of things like: how often to wipe dust off the light bulbs, given 50 different variables, and then contractually write it out.

For every tiny thing, and that was 10+ years ago.
