5. Setup & Charging

Initial Use:

Before first use, ensure the flashlight is fully charged. The battery is pre-installed.

Charging Instructions:

1. Unscrew the back cover of the flashlight.
2. Locate the hidden USB charging port.
3. Plug the flashlight directly into any standard USB device (e.g., computer, mobile power bank, USB wall adapter).
4. The charging indicator light will show the charging status (refer to product for specific indicator behavior).
5. Once fully charged, disconnect the flashlight and securely screw the back cover back on to maintain water resistance.

6. Operating Instructions

Turning On/Off:

Press the power button located on the side of the flashlight to turn the UV light on or off.

Focus Adjustment (Zoom):

To adjust the light beam, gently slide the head of the flashlight forward or backward. This allows you to zoom in for a concentrated beam or zoom out for a wider area of illumination.

Understanding 365nm UV Light:

The 365nm ultraviolet light is largely invisible to the naked eye, appearing as a faint purple glow. This wavelength is superior for revealing fluorescent materials without the distracting visible purple light often associated with 395nm UV flashlights. This makes it ideal for high-demand detection tasks.

7. Applications

Pet Urine & Stain Detection:

Use the flashlight in a darkened room to scan carpets, furniture, and other surfaces. Pet urine and other biological fluids will fluoresce, appearing as bright spots. The zoom function can help pinpoint the exact location of stains.

Anti-Counterfeiting Identification:

The 365nm UV light can reveal security features on currency, passports, and other official documents that are invisible under normal light. This aids in verifying authenticity.

Resin Curing:

The UV light can be used to cure UV-sensitive resins for various crafting or repair projects. Ensure proper ventilation and eye protection during this application.

Mineral & Ore Detection:

Certain minerals and ores exhibit fluorescence under UV light. The 365nm wavelength can help identify these specimens, making it a useful tool for collectors and enthusiasts.

8. Maintenance & Care

• Cleaning: Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Lens Care: Keep the UV lens clean for optimal performance. Use a lens cleaning cloth if necessary.
• Storage: Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery: Recharge the battery regularly to maintain its lifespan, even if not in frequent use.

9. Troubleshooting

• Flashlight not turning on: Ensure the battery is charged. Check if the back cover is securely tightened.
• Weak UV light: Recharge the battery. Ensure the lens is clean.
• Charging issue: Verify the USB cable and power source are functioning correctly. Ensure the USB port on the flashlight is clean and free of debris.
