*Turbo runtime includes reduced-output time from thermal/protection step-down. Specs measured by Fenix using one ARB-L21-5000 V2.0 battery at 21±3°C / 50–80% humidity; real-world performance varies.
Operating Instructions
On/Off: press and hold the side switch for 0.5 seconds to turn the flashlight on/off.
Mode Switching: press and hold the side switch for 1.2 seconds to enter Strobe. Single-click the side switch to select between Strobe and SOS.
Output Selection: with the light on, single-click the side switch to cycle Eco → Low → Med → High → Turbo.
Lock/Unlock: with the light off, double-click the side switch within 0.5 seconds to lock (blinks twice in Low output to confirm). Double-click again within 0.5 seconds to unlock (activates in Low output).
Intelligent Memory Circuit: the light remembers the last-used output level, but only for outputs of 1000 lumens or below (excluding Strobe and SOS).
Battery & Charging
Uses a Fenix ARB-L21 series 21700 battery (3.6V, included). To replace: unscrew the light tail, insert the battery anode side (+) toward the light head, and screw the tail back on. Do not use 16340 batteries or LiFePO4 (18650, 3.2V) batteries — both are banned for this light; other 21700 Li-ion batteries should be used with caution.
To charge: turn off the flashlight, open the anti-dust cover to reveal the USB Type-C port, and connect the charging cable. The indicator glows red while charging and turns green when full — be sure to unplug and close the anti-dust cover once done. Charging from empty takes about 3 hours with a 5V/2A or higher adapter (this light does not support fast charging; only use a certified adapter). The light can be used while charging.
Battery Level Indication
Each time the light is turned on, the indicator shows the current battery level for 3 seconds.
- Green, on: saturated, 100–85%
- Green, flashing: sufficient, 85–50%
- Red, on: poor, 50–25%
- Red, flashing: critical, 25–1%
Protection Features
Intelligent Overheat Protection: at 60°C/140°F or above, the light automatically steps down output to cool down, and gradually restores the preset level once temperature drops.
Low-Voltage Warning: below 3.0V, the light downshifts to Eco. At Eco, the indicator blinks red rapidly and the light itself blinks for 20 seconds as a reminder; single-click the switch to stop the blinking and stay in Eco (usable for 30+ more minutes) until the battery needs recharging.
Care & Maintenance
- Do not disassemble the sealed head — this voids the warranty.
- Use only a high-quality battery.
- Remove the battery for storage if the light won't be used for an extended period.
- Unscrew the light tail or remove the battery during storage/transport to prevent accidental activation.
- Replace the O-ring with an approved spare if it shows wear, to maintain the waterproof seal.
- Clean battery contacts periodically with a rubbing-alcohol-soaked cotton swab if the light flickers or won't turn on.
