Three Light Bulbs: Solution

math image

Turn on TWO of the switches and wait about 15 minutes...

Turn off ONE switch and go down to the basement...

The bulb that is lit matches up to the switch you left on...

The bulb that is off and WARM matches up to the switch that was on, but was turned off...

The bulb that is off and cold matches up to the switch you never touched.
