Tony, that is even more awesome! I see the Falkland problem has disappeared.

The Falkland Islands are much smaller than the red and yellow blob that is shown in the first map, which is very weird. The second map makes much more sense.

But I think I figured out what the problem is. The first map shows night sky brightness *pollution*. So it measures the ratio of artificial versus natural brightness. The bigger the ratio, the more intense is the pollution, but not necessarily brighter.

The second map seems to be only a photograph.
