One possible explanation for the two NK light conditions (dim and none) would be that the regime is on strict "power hours."
IOW, at 8:59 PM, there is light. Then at the sroke of nine PM, at 20 power stations, 20 master switches are thrown (who will argue with an order in NK?) and the country goes dark virtually all at once (except for Dear Leader's palaces etc with their own generators and fuel supplies).
This would be very cool to watch on streaming satellite video, if there is such a thing.
No streaming satellite video that I know of, but
here's that giant NASA composite shot of lights on Earth at night. You can see all of S. Korea is well-lit, then beginning right at the DMZ northwards, almost total darkness. Pitiful.
Uhhhhh . . . Never mind, lol! . . . I just look for the good posters I know and respond to them!
