2. Initial Battery Charging

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.

3. Accessory Attachment (Optional)

Remote Pressure Switch: Replace the standard tail cap with the remote pressure switch for remote activation, often used with weapon mounts.
Weapon Mount: Use the provided weapon mount to attach the flashlight to compatible firearms. Ensure the mount is securely fastened.
Color Filters: The kit includes green and red glass filters. These can be placed over the flashlight head to change the beam color for specific applications like hunting (green for animal vision, red for low-light preservation).

Operating Instructions

1. Power On/Off

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.

2. Mode Selection

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.

3. Thermal Protection

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.

Maintenance

1. Cleaning

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.

2. Battery Care

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.

3. O-Ring Maintenance

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.

Troubleshooting
