Features:
1.Battery type recognition, different battery provides different output.
2.Automatically shift down: When use lithium batteries, voltage is below 2.75V, WK41 turns off automatically.
3. High efficiency constant current driver circuit.
4.Click the switch to change between lighting modes, Double click the switch to access and change between the Hidden modes. In either Hidden mode, pressing the switch once changes to Low mode.
5. Reverse-polarity protection to prevent damage from incorrect battery insertion.
Notice:
Fully charged 14500 lithium batteries with protection circuit are recommended. Because of the different characteristics of different battery types, the flashlight output and low-power indicator levels can vary. In the hidden modes, mode memory and the low-power indicator function are disabled. When the remaining battery capacity is very low, the WK41 may flash. When the WK41 is not to be used for a prolonged period, it is recommended to remove the batteries.
