The Trustfire TR-J18 is a high-power LED flashlight designed for various applications including hunting, surveillance, and general illumination. It features 7 CREE XM-L T6 LEDs, delivering a maximum output of 8500 lumens. The flashlight is constructed from durable anodized aluminum and is water-resistant.

The TR-J18 flashlight operates with either two (2) or three (3) 18650 rechargeable batteries, or three (3) 26650 batteries. Ensure batteries are inserted with the correct polarity.

Before first use, fully charge the included 18650 batteries using the Trustfire 2-battery charger. Connect the charger to a power source and insert the batteries. The indicator light on the charger will show charging status.
To turn the flashlight ON or OFF, firmly press the button on the tail cap. For models equipped with a remote pressure switch, use the switch to control power.
The Trustfire TR-J18 operates in a single, high-power mode. There are no multiple brightness levels or strobe functions. This design is optimized for consistent, maximum illumination.
The flashlight is equipped with a thermal protection system to prevent overheating. Due to its high lumen output, continuous operation for more than 10 minutes is not recommended. The system will automatically reduce output or shut down if the head temperature becomes excessive.
Wipe the flashlight body with a clean, soft cloth. For the lens, use a lens cleaning cloth and solution. Do not use abrasive cleaners or solvents.
Recharge batteries regularly, even if not fully depleted, to maintain optimal performance and lifespan. Remove batteries if the flashlight will not be used for an extended period to prevent leakage.
The flashlight's water resistance relies on its O-rings. Periodically inspect the O-rings for wear or damage. Apply a thin layer of silicone grease to keep them lubricated. Replace damaged O-rings with the provided spares.
