Introduction
The Alonefire SV103/SV101 UV Flashlight is a versatile ultraviolet black light designed for a wide range of detection tasks. This manual provides essential information for the safe and effective use of your UV flashlight, covering setup, operation, maintenance, and troubleshooting.
The flashlight is available in two main configurations: the SV103 with 3x365nm UV LEDs and the SV101 with 1x365nm UV LED. Both models are rechargeable via a Type-C USB interface and are constructed from durable aluminum alloy.
Setup
Battery Installation
The flashlight uses one 18650 battery. To install or replace the battery, unscrew the tail cap, insert the 18650 battery with the positive (+) end facing towards the head of the flashlight, and then securely screw the tail cap back on.
Charging
The flashlight features a convenient Type-C USB charging interface. To charge, locate the rubber cover on the side of the flashlight, open it, and connect a Type-C USB cable to a compatible power source (e.g., mobile phone charger, computer, power bank, car charger). The charging indicator light will show red when charging and green when fully charged.
Operating Instructions
Power On/Off and Mode Selection
- To turn the flashlight on or off, press the power button located on the side of the flashlight body.
- The SV103 model operates in a single high-light mode.
- The SV101 model features two modes: High light and Low light. Press the power button repeatedly to cycle through these modes.
Applications
The UV flashlight is designed for various detection purposes:
- Pet Stain Detection: Ideal for locating dried pet urine stains on carpets, rugs, and other surfaces that are invisible to the naked eye.
- Currency and Document Authentication: Reveals security features on banknotes, passports, licenses, and other official documents.
- Mineral and Gemstone Inspection: Helps identify fluorescent minerals and gemstones.
- Leak Detection: Can be used with UV dyes to detect leaks in automotive systems (e.g., AC, oil) or plumbing.
- Scorpion Finding: Scorpions fluoresce under UV light, making them easier to spot in dark environments.
- Fluorescent Agent Detection: Identifies fluorescent agents in cosmetics, textiles, and other materials.
Maintenance
Battery Care
To prolong battery life and ensure optimal performance, avoid completely draining the battery. Always leave some charge remaining. Over-discharging can damage the battery and prevent the flashlight from functioning.
Cleaning
Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the lens clean for best performance.
Storage
Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the battery to prevent leakage.
Troubleshooting
- Flashlight not turning on:
- Check if the battery is correctly installed with the positive (+) end facing the head.
- Ensure the battery is charged. Connect the flashlight to a Type-C charger and check the indicator light.
- Verify the tail cap is screwed on tightly.
- Dim or weak UV light:
- The battery may be low. Recharge the flashlight.
- The lens might be dirty. Clean it gently with a soft cloth.
- Charging indicator not working:
- Ensure the Type-C cable is securely connected to both the flashlight and the power source.
- Try a different Type-C cable or power adapter.

User Tips
- Optimal Detection: For best results when detecting stains or fluorescent materials, use the UV flashlight in a dark environment. The effect of UV light is significantly enhanced without ambient visible light.
- 365nm vs. 395nm: While this flashlight primarily uses 365nm UV light, it's important to understand the difference. 365nm UV light is less visible to the naked eye but is more effective for detecting high-demand fluorescent agents and security codes, offering a clearer fluorescence without much visible purple glow. 395nm UV light (not the primary wavelength of this product, but often compared) is brighter and shows a more visible purple light, which can sometimes obscure the fluorescence of certain materials.
- Portability: The detachable clip allows for convenient pocket carry, making it easy to transport and access when needed.
