Comment(by cmbarton):

 Did you look at the screenshot? I tried this again with the nc_08 data, to
 make sure it was not something in my files, and have the same results
 (displaying elevation and firestations). The telling thing is to make the
 sphere's fairly large (e.g., 500) and watch the light model as you move
 the puck in the appearance pane.

 For example, set the view to the west (observer puck in the east). Switch
 to the appearance pane and move the lighting puck from east to west. The
 "light model" sphere will go from light to dark. But the vector point
 spheres will go from dark to light. Height is harder to figure out because
 it is also affected by the direction of the light. Height may in fact be
 OK once the horizontal direction is reversed.
