Safety Information
Warning: Ultraviolet (UV) light can be harmful to eyes and skin. Always observe the following safety precautions:
- Do not look directly into the UV light source.
- Avoid prolonged exposure to UV light on skin.
- Keep out of reach of children.
- Use in a well-ventilated area if performing resin curing.
Setup
- Battery Installation: The SV85 flashlight typically comes with a rechargeable Lithium-ion battery pre-installed. If not, unscrew the tail cap, insert the battery with the positive (+) end facing the head of the flashlight, and re-screw the tail cap securely.
- Initial Charge: Before first use, fully charge the flashlight. Connect the supplied USB-C cable to the flashlight's charging port and to a standard USB power source (e.g., computer, wall adapter).

Operating Instructions
- Power On/Off: Press the power button located on the side of the flashlight to turn the UV light on or off.
- Adjusting Focus (Zoom): The SV85 features a telescopic zoom function. Gently push or pull the head of the flashlight to adjust the beam from a focused spotlight to a wider floodlight. This allows for versatile use across different detection or curing needs.

- Charging: When the battery is low, connect the USB-C cable to the flashlight and a power source. The charging indicator light will show red during charging and turn green when fully charged. Charging typically takes 4-6 hours.
Applications
The Alonefire SV85 365nm UV LED Flashlight is suitable for a wide range of applications due to its specific wavelength, which is effective for revealing fluorescent substances.
- Pet Stain Detection: Identify hidden pet urine stains on carpets, rugs, and upholstery that are invisible under normal light.
- Ringworm Detection: Assist in identifying ringworm on pets, as affected areas may fluoresce under 365nm UV light.
- Currency and Document Authentication: Verify the authenticity of banknotes, passports, and other official documents that incorporate UV security features.
- Scorpion Detection: Scorpions fluoresce brightly under UV light, making them easier to spot in dark environments.
- Mineral and Gemstone Inspection: Observe fluorescence in certain minerals and gemstones for identification or quality assessment.
- Resin Curing: Accelerate the curing process of UV-sensitive resins and glues.
- Leak Detection: When used with UV-sensitive dyes, it can help detect leaks in HVAC systems, automotive fluids, and plumbing.

Maintenance
- Cleaning: Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the lens clean for optimal performance.
- Battery Care: To prolong battery life, avoid fully discharging the battery frequently. Recharge the battery regularly, even if not in use, to maintain its capacity.
- Storage: Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures. If storing for extended periods, charge the battery to about 50% and recharge every few months.
