Reverse polarity protection from improper battery installation

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(above 55℃), IF22A is programmed to automatically step down and step up the brightness to prevent over-heating.
