I was playing around with the 1 AAA Rayovac penlight, a (DEAD!) battery, and a Beckman Circuitmate DM73 voltmeter and observed the following:

The LED + booster circuit turns OFF at a battery voltage of 0.215 Volts

The LED + booster circuit turns back ON at a battery voltage of 0.420 Volts

Not bad for a $2.93 flashlight from Walmart!

Does anybody have any measurements on any other flashlights, including even more expensive ones?

The taskforce 1AA works down to pretty low voltage as does the dorcy 1AAA earlier versions.
