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.

Technical Parameters (ANSI/PLATO FL1)

Impact Resistance: 1 meter  |  Waterproof Rating: IP68

*Turbo runtime includes reduced-output time from thermal/protection step-down. Specs measured by Fenix using one ARB-L18-3400U V3.0 battery at 21±3°C / 50–80% humidity; real-world performance varies.

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.

Charging

The light itself has no charging port. The included ARB-L18-3400U V3.0 battery charges through its own USB Type-C port: remove the battery from the light and connect it to a USB power source with the included cable.

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

• If the light won't turn on when new, remove the plastic insulation disc inside the body before first use.
• 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.
