The Fenix LD01 is extremely small, not much bigger than the AAA cell it uses. It has three modes allowing the user to select the best compromise between brightness and runtime for any given task. The Fenix LD01 uses just one common AAA battery and, thanks to its negligible size and weight, it is perfect for every day carry.

Operation:

Turn the head of the flashlight clockwise to turn on the flashlight. A counter-clockwise turn will then switch it off. To switch between output modes, turn the light on, then turn it off. Within 1.5 seconds after turning the light off, turn it on again and it will be switched to the next output mode. Repeat this process to continue switching through the modes. If the light is turned off for over 1.5 seconds, the regulative circuit will be reset and the light will default to its primary mode the next time it is turned on.
