Tuesday Teaser: light bulbs

Imagine you are in a room with 3 switches.

In an adjacent room there are 3 bulbs in lamps which are on a regular table.

All are off at the moment, and each switch belongs to one bulb.

It is impossible to see from one room to another.

How can you find out which switch belongs to which bulb,
if you may enter the room with the bulbs only once?

Any ideas? Post them in the comments section. : )
