note: According to the ANSI/PLATO FL 1 standard, the above specifications are from the results produced by Fenix through its laboratory testing using one Fenrechargeable b ixARB-L 16-700P battery under the temperature of 21±3°C and humidity of 50% – 80%. The true performance of this product may vary according to lo different working environments ts nd the actual battery used.
The Turbo/High output is measured in a total of runtime output at reduced levels due to temperature or protection mechanism in the design. When turned on again the previously used output will be recalled. The high mode will be activated when turned on again if the light is on Turbo mode.

16340 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use quality batteries with circuit protection will reduce the potential for combustion or explosion, but cell damage or short circuiting are potential risks the user assumes.


Unscrew the light tail and insert the battery, with the anode side (+) towards the light head, then screw the light tail back on.


  1. First, switch off the light and plug the USB A socket of the charging cable into an electrical outlet, then connect the USB Type-C socket of the charging cable to the light.
  2. The indicator will display red while charging and will turn green when fully charged.
  3. Once charging is completed, be sure to close the anti-dust cover to maintain the dustproof and waterproof ability.
    The normal charging time of the included Fenix ARB-L16-70OP rechargeable Li-ion battery is approximately 1 hour and 20 minutes from depletion to full charging. Recharge a stored light every four months to maintain the optimum performance of the battery.


Each time the light is turned on, the indicator will indicate the battery level and will last for 3 seconds.

  • Green light on: saturated 100% – 85%
  • Green light flashes: sufficient 85% – 50%
  • Red light on: poor 50% – 25%
  • Red light flashes: critical 25% 1%
  • Note: This only works with Fenix ARB-L16-700P 16340 rechargeable Li-ion battery.

The light will accumulate a lot of heat when used on relatively high modes for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user the reselection of high modes.


When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Moonlight mode is reached. When this happens in Moonlight mode, the light constantly blinks red to remind you to timely recharge or replace the battery.
Note: This only works with Fenix ARB-L16-700P 16340 rechargeable Li-ion battery.
