My rules of thumb:
* if you just want to position a light source somewhere, use the beacon and
leave the position at (0,0,0)
* the main/only good reason for using the position is if you want to attache
the
light source to another object, but not have it at the origin of that object.
(e.g. headlights of a car)
Hope it helps
