Setup
Initial Charge
Before first use, fully charge the spotlight using the provided USB cable. Connect the USB cable to the charging port on the device and to a standard USB power adapter (not included). The power display indicators will show charging progress.
Attaching the Shoulder Strap
Attach the included shoulder strap to the designated loops on the spotlight for easier carrying and hands-free operation.
Using Color Filters
To use a color filter, place the desired colored lens into the lens holder and attach it securely over the main light. These filters are useful for signaling, fishing, or enhancing night vision.
Operating Instructions
Power Button Operation
The spotlight features a single button switch for controlling all lighting modes. Press the button repeatedly to cycle through the available modes.
- Main Spotlight Modes: High Beam → Medium Beam → Strobe.
- COB Side Light Modes: High → Medium → Red & Blue Strobe (Safety Warning Mode).
To turn off the flashlight, continue pressing the button until all modes have cycled and the light turns off. Alternatively, some models may allow a long press to turn off directly from any mode.

Using Color Filters
Once a color filter is attached, activate the main spotlight. The light will project through the chosen filter, providing red, yellow, or blue illumination as needed. These are particularly useful for specific tasks such as night fishing (red/blue), signaling (red), or reducing glare.
