Hypothesis:

This cool astronomer's LED flashlight is really two flashlights in one. There are two power switches, each controlling an LED. An LED is a light emitting diode, which is an electronic device that requires very little current to run, so the batteries last a very long time. Also, LED's do not burn out.
