The data may vary slightly during real-world use due to battery type, individual usage habits and environmental factors.

Operation instructions

Battery installation

Insert one 18650 battery or two CR123 batteries with the positive pole pointing forward (toward the light head).


  1. Ensure batteries are inserted with the positive ( +) end pointing to the head. The P16 will not operate with incorrectly inserted batteries.
  2. Ensure when turning the P16 on, the beam is directed away from the eyes of people or animals.

Switching ON/OFF

To switch ON: Press the button on the tailcap until a “click” is heard.
To switch OFF: Press the button on the tailcap a second lime until a “click” is heard.

General Operations

With the light turned on, press the side switch in quick succession to cycle through the following brightness levels: ultra-low, low, medium and high. Once a desired setting is displayed, ii may be saved by turning the light off at the tail switch.
Note: For user safety and to prevent overheating/ failure, the P16 will automatically switch to a lower mode after three minutes of use at its highest level of output.

Special Modes

With the light turned on, press and hold the side switch lo activate Strobe mode. Press and hold once again to access Location Beacon mode and repeat once more for SOS mode. To exit any one of these modes simply press the side switch lo be returned lo your previously used brightness level.
NB: Strobe mode is the default special mode and is the only special mode that has a memory function. If the light is turned off at the tail switch while in strobe mode, strobe will resume when the light is next turned on. SOS and Location Beacon modes have no memory function.

Power Tips

  1. With the light switched on, the power indicator will blink once every two seconds when power levels reach 50%.
  2. With the light switched on, the power indicator will blink rapidly when power levels are low.
  3. With the light turned off, press and hold the side switch while simultaneously pressing the tail switch lo display the battery voltage (accurate lo ±0.1V) with a series of blinks. For example, when the battery voltage is at a maximum charge of 4.2V, the power indicator will blink 4 times in quick succession, followed by a one second pause and two more blinks, indicating a total battery voltage of 4.2V.

Changing Batteries

When the power indicator blinks rapidly this indicates the batteries need to be replaced. Alternatively if the light becomes dim or unresponsive to adjustment this also indicates batteries need to be replaced.


Every 6 months, threads should be wiped with a clean cloth followed by a thin coating of silicon-based lubricant.
