Setup

1. Initial Battery Preparation

The WUBEN L3 flashlight comes with a pre-installed battery. Before first use, ensure that any protective film or insulator is removed from the battery terminals. The battery is typically installed with a protective cover over the negative end for shipping purposes. Unscrew the tail cap, remove the protective cover, and re-tighten the tail cap securely.

2. Initial Charging

It is recommended to fully charge the flashlight before its first use to ensure optimal performance and battery longevity.

1. Locate the USB-C charging port. This is typically found near the head of the flashlight, beneath a screw-off ring or a rubber cover.
2. Open the rubber cover or unscrew the ring to expose the USB-C port.
3. Connect the provided USB-C charging cable to the flashlight and to a compatible USB power source (e.g., wall adapter, computer USB port).
4. The charging indicator light will illuminate (e.g., red for charging, blue for fully charged).
5. Charging typically takes approximately 2 hours for a full charge using an 18W power source.
6. Once fully charged, disconnect the cable and securely close the USB-C port cover to maintain water resistance.

Maintenance

• Cleaning: Wipe the flashlight with a clean, soft cloth. For stubborn dirt, use a slightly damp cloth. Do not use abrasive cleaners or solvents.
• O-rings: Periodically inspect the O-rings for wear and tear. Replace them with the provided spare O-rings if necessary to maintain the IP68 waterproof rating. Apply a thin layer of silicone grease to the O-rings to ensure a good seal and prevent drying.
• Threads: Keep the threads of the tail cap clean and lubricated.
• Storage: If storing the flashlight for an extended period, charge the battery to approximately 50% and store it in a cool, dry place. Recharge every 3-6 months to prevent deep discharge.
