Additional Functions: Battery type recognition, Automatic shift down, over-discharge protection
Battery type recognition, different battery provides different output
Automatically shift down: When use lithium batteries, H2 could switch to high from turbo automatically. and voltage is below 3.0, it switch to Low mode, and voltage is below 2.75V, H2 turn off automatically.
Dual light sources, main light is for lighting and secondary light is for Signal use.
Click the switch to change between lighting modes, Double click the switch to access and change between the signal modes. In either signal mode, pressing the switch once changes to Low mode.
Reverse-polarity protection to prevent damage from incorrect battery insertion
Because of the different characteristics of lithium batteries and Li-ion batteries, the light output and runtime can vary
Fully charged 3.6 V/3.7V 16340 lithium battery with protection circuit is recommended.
Only when using fully charged 3.6V/3.7V 16340 lithium batteries, the H2 provides Turbo mode and battery over-discharge protection.
When using incompletely charged 16340 lithium batteries, the H2 will operate as if a CR123A battery is being used.
When the H2 is not to be used for a prolonged period, it is recommended to remove the batteries.
