I didn't mean compete in terms of max lux output, though if they actually wanted to do that for whatever odd reason (film studio? indoor weed farming?), the basic tech probably could as well.

I meant effective task lighting for multiple people and multiple tasks across seasons in a large building with multiple very similar large rooms that have windows in different places but usually along one wall only (in a valley, in a cloudy country relatively far from the equator).

Which on the face of it, seems totally absurd. Things such as Night School, and schools/offices near the poles for example, exist. Is there something more specific that you're actually saying?

Especially children need significant time spent in bright daylight in order to develop normally. It's not beyond our technology, but nobody actually does it.
