> The nearest turbine is over five miles away ... a bright red light at the top ... with about 20 of those lamps visible it destroys the night darkness ... even for a good night's sleep That sounds like a measurable decrease in quality, but to be fair you're starting from a highly unusual baseline. And I don't mean to be uncharitable, but when it comes to sleep effects (reported by others, apparently), I suspect that the light emitted from tower-mounted aircraft lights at a distance of five miles has a greater effect on their psychological perception than on their photon receptors. The light "pollution" of a full moon is surely larger than the tower lamps. And more variable over the night (the moon moves, towers do not).

point sources are more intense than diffuse sources.

  The moon is effectively a point source of light. Of course it's neither a point nor a source, but in the night sky it acts like one. In dark locations, the moon can be bright enough to cast shadows indoors.
