Operating Instructions

Continuous Dimming Function
For precise brightness control, use the continuous dimming feature:
- While the flashlight is on in Continuous Dimming mode (via the right switch), press and hold the right switch.
- The brightness will smoothly adjust between 500 and 1,000,000 lumens.
- Release the button once your desired brightness level is achieved.

Focus Adjustment (Floodlight/Spotlight)
The flashlight features a variable focus design to adapt to different lighting needs:
- Gently push or pull the head of the flashlight forward or backward.
- Pushing the head forward will narrow the beam into a focused spotlight, ideal for long-distance illumination (over 1500m).
- Pulling the head backward will widen the beam into a floodlight, suitable for illuminating a broad area (up to 280m²).

The flashlight is equipped with a built-in USB-C charging port and can also function as a power bank:
- Charging the Flashlight: Connect the included USB-C cable to the flashlight's charging port and plug the other end into a USB power source (e.g., wall adapter, car charger, computer). The LCD display will show the charging progress.
- Power Bank Function: In an emergency, you can use the flashlight's USB output port to charge other devices, such as your mobile phone. Connect your device to the flashlight using a compatible USB cable.
