Fenix GL30R Reference ManualUpdated 24 minutes ago

Condensed information from the manufacturer's official manual for the Fenix GL30R tactical light. See the downloadable PDF reference manual on the product page for complete details.

Warning

Do not place this tactical light within reach of children.
Do not shine this tactical light directly into the eyes of anyone.
Do not place the light head near flammable objects — high temperatures can cause objects to overheat and become flammable/ignite.
Do not use this tactical light in inappropriate ways such as holding the unit in your mouth; doing so could cause serious personal injury or death if the tactical light or internal battery fails.
This tactical light will accumulate a significant amount of heat while operating, resulting in a high temperature of the light shell. Pay close attention to avoid burns.
Remove the battery or loosen the light head to prevent accidental activation when the tactical light is placed in a closed, flammable environment such as pockets or backpacks.
The LED of this tactical light is not replaceable; the whole tactical light must be replaced when the LED reaches the end of its lifespan.

Technical Parameters (ANSI/PLATO FL1)

ARB-L18-3400: Output 800 lumens, Runtime 135 minutes*, Max Distance 630 meters, Max Intensity 100,000 candela
2 x CR123A: Output 800 lumens, Runtime 70 minutes, Max Distance 630 meters, Max Intensity 100,000 candela

Impact Resistance: 1 meter | Submersible/Waterproof: IP68 (GL30R alone), IP66 (GL30R + AER-07 attached)

*Output is measured in a total of runtime including output at reduced levels due to temperature or protection mechanism in the design. Specs measured by Fenix using one ARB-L18-3400 rechargeable battery or two CR123A batteries at 21±3°C / 50–80% humidity; real-world performance varies.

Mounting

The GL30R comes with two standard Picatinny rail (MIL-STD-1913) mount kits and one M-Lok mount kit for flexible installation at any position on the rail. The included AER-07 also comes with its own Picatinny and M-Lok mount kits. After connecting the AER-07 to the GL30R, rotate its plug to lock it securely. For optimal performance, ensure all screws are fully tightened during installation.

Operating Instructions

GL30R Tactical Tail Switch: fully press the tactical tail switch to turn the light on/off. With the light off, tap the switch to momentarily turn it on. Note: when the GL30R is turned on with the tail switch, it cannot be turned off with the AER-07.

AER-07 Tactical Remote Pressure Switch: features a side locking slider to lock/unlock both switches. Switch 1 is a forward-clicky switch (single click to turn the light on/off); Switch 2 is a silent switch (single click to momentarily turn the light on). Note: when the GL30R is turned on with the AER-07, it cannot be turned off with the tail switch — disconnect the AER-07 to turn off the GL30R.

Battery Specifications & Installation

Fenix ARB-L18-3400 (18650, 3.6V): Recommended
Other 18650 Battery (18650, 3.6V): Usable
2 x CR123A (3.0V): Usable

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

Charging & Battery Level Indication

Connect the USB Type-C charging cable (after removing the AER-07). The indicator shows red while charging and turns green when fully charged; a full charge of the ARB-L18-3400 takes about 2 hours with a 5V/3A adapter (5V, max 12W/2.4A — does not support fast charging; do not charge while using two CR123A batteries).

Each time the light is turned on, the indicator shows battery level for 3 seconds: green on (100–85%), green flashing (85–50%), red on (50–25%), red flashing at 6Hz (25–1%). Battery level indication only works with a Fenix ARB-L18 series battery.

Intelligent Overheat Protection & Low-Voltage Warning

At 60°C/140°F or above, the light automatically steps down output to reduce temperature, recalling the preset level once it cools below that threshold. When voltage drops below the preset level, output gradually decreases; the indicator blinks rapidly to signal it's time to recharge or replace the battery (ARB-L18 series only).

Usage and Maintenance

Disassembling the sealed head can cause damage and will void the warranty.
Fenix recommends using an excellent quality battery.
If the light won't be used for an extended period, remove the battery to prevent electrolyte-leakage damage.
Clean the lens regularly, and replace the O-ring if worn to maintain a proper water seal.
Avoid contaminating internal components with organic solvents during maintenance — this voids warranty service.
Periodic cleaning of battery contacts (cotton swab + rubbing alcohol) prevents flickering or failure to illuminate from dirty contacts; a poor battery charge should be recharged or replaced.
If issues persist, contact your authorized distributor.
