Package Contents
- 2 x Hilngav UV Blacklight Flashlight (365nm)
- 2 x Hilngav UV Blacklight Flashlight (395nm)
- 4 x USB-C Charging Cable
Wavelength Characteristics
Understanding the difference between the two UV wavelengths is crucial for optimal use:
UV 365nm Flashlight
- Wavelength: 365 nanometers.
- Detection: Excites more fluorescent molecules, leading to a generally better detection effect.
- Visual Appearance: In dark environments, the emitted light appears relatively light, more bluish-white. The purple light is purer with less visible light interference to the naked eye. Ideal for detecting subtle fluorescents.
UV 395nm Flashlight
- Wavelength: 395 nanometers.
- Detection: Excites a relatively smaller number of fluorescent molecules compared to 365nm. May be less sensitive to some specific fluorescent substances.
- Visual Appearance: The emitted light appears relatively dark, closer to purple, and contains more visible light, making it look brighter. Suitable for general purpose UV detection where strong visible purple light is acceptable.
Setup
- Unpack: Carefully remove all flashlights and USB-C cables from the packaging.
- Initial Charge: It is recommended to fully charge the flashlights before first use. Refer to the "Charging" section for instructions.
- Identify Wavelengths: Each flashlight is marked with its wavelength (e.g., "S22-UV365nm" or "S22-UV395nm"). Familiarize yourself with which flashlight corresponds to which wavelength for appropriate application.
Charging
The Hilngav UV flashlights are equipped with built-in rechargeable lithium-ion batteries and a USB-C charging port.
- Connect Cable: Insert one end of the provided USB-C charging cable into the flashlight's USB-C port.
- Connect Power: Connect the other end of the USB-C cable to any standard USB power source (e.g., wall adapter, computer USB port, power bank).
- Charging Indicator: The flashlight will typically have an indicator light to show charging status. (Note: Specific indicator behavior may vary slightly. Refer to product markings if available.)
- Full Charge: Allow approximately 1 hour for a full charge. Disconnect the flashlight once charging is complete to preserve battery life.
Important: Use only the provided USB-C cables or other standard USB-C cables. Ensure the power source provides appropriate voltage (e.g., 5V USB standard).

Operating Instructions
- Power On/Off: Press the power button located at the top of the flashlight to turn it on. Press again to turn it off.
- Optimal Use: For best results in detecting fluorescent materials, use the flashlight in a dimly lit or dark environment.
- Safety Precautions:
- Do not shine the UV light directly into eyes or at other people/animals.
- Keep out of reach of children.
- Avoid prolonged exposure to skin.
Applications
The Hilngav UV flashlights are versatile tools for various detection and curing tasks:
- Pet Urine Detection: Ideal for locating dried pet urine stains on carpets, rugs, and upholstery. The 365nm flashlight may offer clearer contrast for some stains.
- Resin Curing: Suitable for curing UV resin for crafts and repairs.
- Currency Verification: Detects security features on banknotes that fluoresce under UV light.
- Fluorescent Agent Detection: Identifies fluorescent agents in cosmetics, detergents, and other materials.
- Scorpion Detection: Scorpions fluoresce under UV light, making them easier to spot in dark environments.
- Mineral and Gemstone Inspection: Some minerals and gemstones exhibit fluorescence, aiding in identification.
- Uranium Glass Testing: Confirms the presence of uranium in glass, which glows brightly under UV light.
- General Cleaning Inspection: Reveals hidden dirt, grime, and biological residues not visible to the naked eye.

Maintenance
- Cleaning: Wipe the flashlight body with a soft, dry cloth. Do not use abrasive cleaners or immerse in water.
- Storage: Store the flashlights in a cool, dry place away from direct sunlight and extreme temperatures.
- Battery Care: For optimal battery longevity, avoid fully discharging the battery frequently. Recharge when the light output diminishes. If storing for extended periods, charge the battery to approximately 50% every 3-6 months.
- Material: The flashlight body is made of quality aluminum, which is durable and resistant to rust.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flashlight does not turn on. | Battery is depleted. | Charge the flashlight using the provided USB-C cable. |
| Flashlight does not charge. | Charging cable or adapter is faulty; USB-C port issue. | Try a different USB-C cable or power adapter. Ensure the cable is fully inserted. |
| Light output is dim. | Low battery level. | Recharge the flashlight. |
| Cannot detect stains effectively. | Environment is too bright; incorrect wavelength used for specific stain. | Use in a darker environment. Experiment with both 365nm and 395nm flashlights as different substances fluoresce best under different wavelengths. |
