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, SP35 is programmed
to automatically step down and step up the brightness. These thresholds are set at 45°C, 55°C and
65°C. The higher the temperature gets, the more the brightness will drop. Once temperature
decreases, brightness will be increased again according to your selected mode.

Battery Type
Rechargeable li-ion battery
Battery Installation
Unscrew the tailcap to insert one
21700 battery with the anode
side (+) towards the head, then
screw the tailcap back on.
Important advice: If you
purchased SP35 with a battery
included, please make sure to remove the insulating paper on the negative battery pole and charge the
battery before first use.
Power Indicator
The LED indicator in the side switch shows the power status for 5 seconds after turning SP35 on.
Green = remaining battery power is good.
Red = remaining battery power is poor (less than 30%).
Flashing Red = critical power, replace or recharge battery as soon as possible.
