Introduction
Thank you for choosing the DARKBEAM 501BX IR 850nm Infrared Flashlight. This device is specifically designed as an infrared illuminator to enhance night vision equipment, such as night vision scopes or cameras. It emits 850nm infrared light, which is largely invisible to the naked human eye. This manual provides essential information for the safe and effective use of your infrared flashlight.
Important Note: This is not a standard visible light flashlight. You will only see a faint red glow from the LED when it is on. A night vision device is required to utilize its illumination capabilities.

- Screw the tail cap back on securely.
2. Initial Charging
Before first use, fully charge the battery.
- Connect the USB charger to a 5V/1A USB power source (e.g., power bank, laptop, USB wall adapter).
- Insert the rechargeable battery into the USB charger.
- The charger's indicator light will show charging status (typically red for charging, green for fully charged).
- Charging typically takes approximately 3 hours.
Operating Instructions
1. Power On/Off
- To turn the flashlight on, press the button on the tail cap.
- To turn the flashlight off, press the button again.

2. Adjusting Focus (Zoom)
The flashlight features a telescopic focusing head to adjust the beam.
- To Zoom In (Narrow Beam): Extend the flashlight head forward. This concentrates the IR light for a longer, more focused beam, ideal for distant targets (up to 500 meters).
- To Zoom Out (Wide Beam): Retract the flashlight head backward. This spreads the IR light for a wider area of illumination, suitable for closer observation.

3. Usage with Night Vision Devices
The DARKBEAM 501BX is an infrared illuminator, meaning it provides supplemental IR light for night vision devices. It does not produce visible light for general illumination.
- Ensure your night vision scope or camera is active.
- Turn on the IR flashlight.
- Adjust the focus of the flashlight to match your observation distance and field of view.
- This setup is ideal for activities such as hunting, wildlife observation, outdoor search, and photography in low-light or no-light conditions.

Maintenance
Battery Care
- To preserve battery life, charge the battery every two months if the flashlight is not in regular use.
- Avoid fully discharging the battery frequently, as this can reduce its overall lifespan.
Cleaning and Storage
- Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners.
- Keep the lens clean for optimal performance. Use a lens cleaning cloth if necessary.
- Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures.
Water Resistance
The flashlight is designed to be water-resistant (IP65X standard met), making it suitable for use in wet environments. However, it is not intended for submersion. Ensure the tail cap is securely tightened to maintain water resistance.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flashlight does not turn on. |
|
|
| Weak or inconsistent IR light. |
|
|
| Cannot see IR light with naked eye. | This is normal behavior. | The 850nm infrared light is largely invisible to the human eye. It requires a night vision device to be seen. You should only observe a faint red glow from the LED itself. |
