Safe Use Warnings
- Keep this light out of the reach of children.
- Do NOT shine the light directly into the eyes of anyone.
- Do NOT shine the light 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-threatening risk 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, flammable environment such as a pocket or backpack.
- 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
Switch: the tail switch is the tactical switch and the side switch is the functional switch.
On/Off: tap the tactical switch to momentarily turn on the light (release and it goes out), or fully press to turn it on constantly (press again to turn off).
Output Selection: with the light on, single-click the functional switch to cycle Turbo → Eco → Low → Med → High.
Strobe: with the light on, press and hold the functional switch for 0.5 seconds to enter Strobe; single-click again to return to the previously used general-mode output.
Intelligent Memory Circuit: the light remembers the last-used output level (excluding Strobe) and recalls it the next time it's turned on.
Battery & Replacement
Uses a Fenix ARB-L18 series 18650 battery (3.6V/3.7V, recommended), and is also compatible with CR123A lithium (usable) and 16340 LiFePO4 (usable). Other 18650 Li-ion batteries should be used with caution; 16340 Li-ion and 18650 LiFePO4 batteries are banned for this light. Don't mix batteries of different brands, sizes, capacities, or types. To replace: unscrew the light tail, insert the battery anode side (+) toward the light head, and screw the tail back on.
Battery Level Indication
Each time the light is turned on, the indicator in the functional side switch shows 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%
Note: This only works with a Fenix ARB-L18 series 18650 battery.
Protection Features
Intelligent Overheat Protection: at 60°C or above, the light automatically steps down a few lumens to cool down, and allows reselecting modes once temperature drops below 60°C.
Low-Voltage Warning: as the battery depletes, the light automatically downshifts toward Eco; in Eco, the indicator blinks red as a reminder to recharge or replace the battery. Works only with a Fenix ARB-L18 series 18650 battery.
Care & Maintenance
- Do not disassemble the sealed head — this voids the warranty.
- Use only a high-quality protected battery.
- Remove the battery for proper storage if the light won't be used for an extended period.
- Unscrew the tail cap 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.
