no specifics of "artificial light" definition anywhere.

Not sure I'm following your thinking here; what light sources are you unclear about w/ regard to their status as artificial or not?

most literature makes distinctions on blue, red lights for sleep impact. they just named it artificial night light, even included the moon there.
