Three Plugs Puzzle

Guess which plug lights up the lamp.

You do not see the lamp, the lamp is hidden under a black box which does not allow neither light nor heat to go through.  The only things available are the three plugs and an electrical outlet.

You can plug in the plugs in any sequence you like, before you open the box.  But when you open the box you will have to guess which plug lights up the lamp.

How do you do that?
