Technical Parameters (ANSI/PLATO FL1)

  • Turbo: 3000 lumens, 1 hour*, 470 meters, 55,200 cd
  • High: 1400 lumens, 2 hours, 300 meters, 22,500 cd
  • Med: 400 lumens, 7 hours, 160 meters, 6,400 cd
  • Low: 100 lumens, 29 hours, 80 meters, 1,600 cd
  • Eco: 30 lumens, 68 hours, 52 meters, 520 cd
  • Strobe: 3000 lumens
  • SOS: 100 lumens

Impact Resistance: 1 meter. Submersible: IP68. *The Turbo output is measured in a total of runtime including output at reduced levels due to temperature or protection mechanism in the design. According to the ANSI/PLATO FL1 standard, the above specifications are from Fenix's laboratory testing using one Fenix ARB-L21-5000 rechargeable Li-ion battery under 21±3°C and 50-80% humidity; real-world performance may vary.

Safe Use Warnings

  • Do not place this light out of the reach of children.
  • Do not shine the light directly into the eyes of anyone.
  • Do not shine at flammable objects at close range, to avoid burning objects or causing danger due to high temperature.
  • Do not use the light in inappropriate ways such as biting it in the mouth, to avoid personal injury or life threats if the light or internal battery fails.
  • This light will accumulate a lot of heat while working, resulting in a high temperature of the flashlight shell. Pay attention to safe use to avoid scalding.
  • Turn off and lock the light or remove the battery to prevent accidental activation when the light is placed in a closed and flammable environment such as pockets and backpacks.
  • The LED of this flashlight is not replaceable; the whole light should be replaced when the LED reaches the end of its life.

Operating Instructions

On/Off: With the light switched off, press and hold the side switch for 0.5 seconds to enter general mode. With the light switched on, press and hold the side switch for 0.5 seconds to turn off the light.

Mode Switching: With the light switched on, press and hold the side switch for 1.2 seconds to switch between general mode and flash mode.

Output Selection: In general mode, single click the side switch to cycle through Eco→Low→Med→High→Turbo. In flash mode, single click the side switch to cycle through Strobe→SOS.

Intelligent Memory Circuit: The light memorizes the last selected output in general mode. When turned on again, the previously used output will be recalled. The light will always enter Strobe when flash mode is selected.

Lock/Unlock: Lock: with the light switched off, double click the switch within 0.5 seconds to lock the light; the light will blink twice on Eco to indicate locked status. Unlock: with the light locked, double click the switch within 0.5 seconds; the light will be unlocked and activated on Eco. In locked status, clicking or pressing the switch will activate two one-second blinks on Eco to indicate locked status.

Battery Specifications

  • Fenix ARB-L21 Series: 21700, 3.6V/3.7V — Recommended
  • Rechargeable Battery (Li-ion), non-Fenix: 21700, 3.6V/3.7V — Use with caution

*21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using 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.

Battery Replacement

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

Charging

  • Reveal the USB Type-C charging port 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.
  • The normal charging time is approximately 3 hours from depletion to full charge with the light switched off. The flashlight can be used normally on Eco mode while charging, though charging time will be prolonged.
  • The indicator will display red while charging and will turn green when fully charged.
  • Once charging is completed, be sure to replace the USB cap to maintain the dustproof and waterproof ability.

*The charging input is 5V/2A; an adapter or mobile power bank of this specification can be used to charge the flashlight. Recharge a stored light every four months to maintain optimal Li-ion battery performance.

Battery Level Indication

With the light switched off, single click the switch to check the battery status; the indicator 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%

*This only works with a Fenix ARB-L21 series 21700 battery.

Intelligent Overheat Protection

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

Intelligent Downshift / Low-Voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco mode is reached. If the light is turned off on Turbo or High mode, when turned on again it will be activated on Med mode. When the voltage remains low in Eco mode, the light constantly blinks red to remind users to recharge or replace the battery in a timely manner. *This only works with a Fenix ARB-L21 series 21700 battery.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty.
  • Fenix recommends using only a high-quality protected battery.
  • If the light will not be used for an extended period, remove the battery for proper storage.
  • Lock the light or remove the battery to prevent accidental activation during storage or transportation.
  • Long-term use can result in O-ring wear. To maintain a proper water seal, replace the O-ring with an approved spare.
  • Periodic cleaning of the battery contacts improves the light's performance, as dirty contacts may cause the light to flicker, shine intermittently, or fail to illuminate. A. Poor battery level — recharge the battery. B. Dirty contact points — clean with a cotton swab soaked in rubbing alcohol. If the above methods don't work, please contact your authorized distributor.
