The above mentioned parameters are based on tests according to international flashlight testing
standards (ANSI/NEMA FL1) using one 700mAh 16340 Li-ion battery in our laboratory. Results may vary
with different battery or under different environmental conditions. Operation temperature is 0°C -
40°C.

Low voltage warning: When the battery voltage is too low, the LED indicator in the side switch will
start to flash rapidly. Please recharge the battery.
Low voltage protection: The flashlight steps down automatically when the voltage is lower than 3.0V.
It also turns off automatically if the voltage gets too low. Please recharge the battery.
Advanced Temperature Regulation (ATR) technology: As the temperature rises, SC21 Pro is
