Hah! If the earth was not curved height would not be the primary
determinant of geographic range. You've still ignored the question of
color which has a very large effect.

Yes, I do prefer more complete answers. The idea here
is to pass on information to other readers. Details count.

It is remarkable that you prefer a long winded yet incomplete answer to
that which gives _all_ the factors without being longwinded. Was may
answer not precise enough?

Same for you. Need a little more detail to get a point for the one
question listed below.

What are the factors that determine a single light's visible range?

The height and the brightness


To be more precise, the height determines the geographic range while
visible range is limited by conditions as well as luminosity and colour.
