Warning

Keep this light out of the reach of children.
Do not shine the light directly into anyone's eyes.
Do not shine 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 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 from the light 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; so the whole light should be replaced when the LED reaches the end of its life.

Operating Instructions

On/Off: With the light unlocked and switched off, press and hold the switch for 0.5 seconds to turn on the light. With the light switched on, press and hold the switch for 0.5 seconds to turn it off.

Output Selection: Single click the switch to cycle through Eco→Low→Med→High→Turbo.

Mode Switching: Press and hold the switch for 1.2 seconds to enter Strobe; single click the switch again to return to the last used output in general mode.

Lock/Unlock: With the light unlocked and switched off, double click the switch to lock it — the light will blink twice on Eco to indicate locked status. With the light locked and switched off, double click the switch to unlock it — 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

Rechargeable Li-ion battery (21700, 3.6V). It is recommended to use Fenix Li-ion power batteries, or the 10,000 lumens maximum output may not be reached.

21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Use only quality batteries with circuit protection to reduce the potential for combustion or explosion; cell damage or short circuiting are risks the user assumes.

Battery Replacement

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

Charging

Switch off the light and plug the USB A end of the charging cable into an electrical outlet, then connect the USB Type-C socket of the charging cable to the light. The indicator displays red while charging and turns green once fully charged; be sure to close the anti-dust cover once charging is complete.

Normal charging time is approximately 3 hours 30 minutes from depleted to fully charged.
Only Eco output is available while charging.
Recharge a stored light every four months to maintain optimum performance of the battery.

Battery Level Indication

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

Intelligent Memory Circuit

The light memorizes the last selected output of general mode. When turned on again, the previously used output of general mode will be recalled.

Intelligent Overheat Protection

The light will accumulate a lot of heat when used at Med, High, or Turbo output levels for extended periods. When the light reaches a temperature of 65°C or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 65°C, it will then allow the user to reselect the previous output.

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 output is reached.

Impact Resistance: 1 meter.
Waterproof: IP68, 2 meters underwater.

Note: The above specifications are the test results produced by Fenix through its laboratory testing using the included Fenix ARB-L21-4000P rechargeable Li-ion power batteries, 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 protection mechanism in the design.

Usage and Maintenance

Disassembling the sealed head can cause damage to the light and will void the warranty.
Fenix recommends using an excellent quality battery.
If the light will not be used for an extended period, remove the batteries, or the light could be damaged by electrolyte leakage or battery explosion.
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 ring with an approved spare.
Periodic cleaning of the battery contacts improves the lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons: the battery needs replacing (recharge or replace the battery); or the threads, PCB board contact or other contacts are dirty (clean with a cotton swab soaked in rubbing alcohol).
If the above methods don't work, please contact your authorized distributor.
