I like this, but to play the devil’s advocate: How does that mesh with usually having just one giant overhead light (the sun) outdoors?

You mean one giant overhead light (the sun) during "work hours" and a soft reddish ground-level light (the campfire) during night?

Its moves, and twice a day its nice and low like a lamp. In the middle of the day when its highest, its nice to shelter under a tree where there is dappled light filtering through the leaves.
