4. UV Light Applications (365nm)
The 365nm UV light is ideal for professional detection tasks. It is less visible to the naked eye than 395nm UV light, making it more effective for revealing fluorescent agents and security codes. For best results, use in a dark environment.
- Pet Urine Detection: Easily spot dried pet urine stains on carpets, rugs, and furniture.
- Scorpion Detection: Scorpions fluoresce under 365nm UV light, making them easier to locate.
- Currency and Document Authentication: Verify security features on banknotes, passports, licenses, and other official documents.
- Oil Stains and Leakage Detection: Identify hidden oil leaks in machinery or automotive systems.
- Mineral and Ore Identification: Observe fluorescence in various minerals and ores.
- Art and Antique Conservation: Detect repairs or alterations in art, furniture, and other collectibles.
- Deep Cleaning Helper: Detect hard-to-see stains on carpets, sofas, walls, and bathrooms.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flashlight does not turn on. | Battery not installed correctly or discharged. Insulation film not removed. | Ensure battery is inserted with correct polarity. Remove battery insulation film. Charge the battery fully. |
| UV light appears dim. | 365nm UV light is less visible to the naked eye than 395nm. Presence of fluorescent substances is required for visible effect. | This is normal for 365nm UV. Use in a dark environment for best results. Ensure the object being inspected contains fluorescent material. |
| Flashlight not charging. | Loose cable connection or faulty charging cable/adapter. | Check Type-C cable connection. Try a different USB adapter or cable. |
| Power bank function not working. | Flashlight battery is too low or cable connection is loose. | Ensure flashlight battery is sufficiently charged. Check USB-A cable connection to the device. |
