Warning

Do not shine the flashlight directly into the eyes of anyone.
All information provided in this manual is subject to change without prior notice.
Place this flashlight out of the reach of children.
Do not place the light head near flammable objects; high temperatures can cause objects to overheat and become flammable/ignite.
Do not use the flashlight in inappropriate ways such as holding the unit in your mouth — doing so could cause serious personal injury or death if the flashlight or internal battery fails.
This flashlight will accumulate a significant amount of heat while operating, resulting in a high temperature of the flashlight shell. Pay close attention to avoid burns.
Turn off and lock the light or take out the battery to prevent accidental activation during storage or transportation.
The LED of this flashlight is not replaceable; the whole flashlight will need to be replaced when the LED reaches the end of its lifespan.

Note: the above specifications are from the results produced by Fenix through its laboratory testing using the Fenix ARB-L21-5000 V2.0 battery, under the temperature of 21±3°C and humidity of 50%-80%. The true performance of this product may vary according to different working environments and the actual battery used. *The Turbo output is measured in total of runtime including output at reduced levels due to temperature or the protection mechanism in the design.

Battery Specifications

Fenix ARB-L21-5000 V2.0 (21700, 3.6V): Recommended.
Fenix ARB-L21-5000U (21700, 3.6V): Recommended.
Fenix ARB-L21-4000P (21700, 3.6V): Recommended.
Other types of 21700 battery (21700, 3.6V): Caution.

Warning: it is strictly prohibited to use an 18650, CR123A, or 16340 battery. 21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only using quality batteries with circuit protection will reduce the potential for combustion or explosion. Cell damage or short circuiting are considered user-induced damage and are not covered by any Fenix warranty or liability.

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

Loosen the light head to 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 indicator will display red while charging and will turn green when fully charged.
Once charging is completed, be sure to tighten the light head to maintain the dustproof and waterproof ability.

Note: when charging fails or the battery is reversely connected, the battery indicator will flash red to remind the user to check the battery. The normal charging time of the flashlight is about 3.5 hours from depletion to fully charged. The flashlight cannot be operated while charging. This feature only works with a Fenix ARB-L21 series battery.

Battery Level Indication

Each time the light is turned on, the indicator (unscrew the light head to see) 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 feature only works with a Fenix ARB-L21 series battery.

Intelligent Overheat Protection

The flashlight will accumulate a lot of heat when used at high output levels for extended periods. When the light reaches a temperature of 60°C/140°F or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C/140°F, the light will gradually recall the preset output level.

Low-Voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output, the light blinks 3 times every 5 minutes to remind you to recharge or replace the battery. This feature only works with a Fenix ARB-L21 series battery.

Usage and Maintenance

Disassembling the sealed head can cause damage to the light and will void the warranty.
Fully charge the light in time to ensure normal function the next time it is needed.
Fenix recommends using an excellent-quality battery.
If the light will not be used for an extended period, remove the battery, or the light could be damaged by electrolyte leakage or battery explosion.
Turn off and lock the light or take out 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 ring with an approved spare.
Periodic cleaning of the battery contacts improves the lamp's performance, since dirty contacts may cause flickering, intermittent operation, or failure to illuminate — check for a poor battery level or dirty contacts, and contact your authorized distributor if cleaning doesn't resolve it.
