It constrains the light to within a cylinder so it won't illuminate 
anything that is not within it's path just like a laser pen,  so if you 
stick a media through it, it will show the path in the same way shining a 
laser pen through smoke will. All of the light_sources act in this way, 
they won't light up anything not in their path, the default point_light of 
course shines light in all directions. Take a look at spotlite.pov in the 
scenes/lights directory in fact have a look at most of that directory if 
you want to know more about lights

I think Alain has answered this one.
