Picatinny Rail Adapter

The GL4 comes with a Picatinny Rail Adapter for easy attachment
to firearms.

Temperature Control

The GL4 features Intelligent Temperature Control that maintains
a temperature range of 45-50 degrees Celsius.

Mode Memory

The Outdoor Setting has mode memory, meaning the flashlight will
remember the last mode used before being turned off.

Shock Resistance

The dual spring protected battery compartment reduces shock to
the battery.

Recharging

The GL4 can be recharged using the included charging cable and a
21700 li-ion battery. The max charging current is 2A (5000mAh) and
it takes 4 hours to fully charge. Charging indicators are Red –
Charging and Green – Full. The capacity indicator will turn on for
5 seconds after power on to indicate the battery capacity. Green
indicates 70%-100%, Orange indicates 30%-70%, and Red indicates
less than 30% battery capacity. The battery drain is less than
80uA.
