- Currency and ID Verification: The 365nm UV light can reveal security features on banknotes, passports, and other official documents that are invisible to the naked eye, aiding in counterfeit detection.
- Resin/UV Glue Curing: Suitable for curing UV resin, UV glue, and nail polish, providing efficient and quick hardening.
- AC Leak Detection: Can be used to detect leaks in automotive AC systems when a fluorescent dye has been introduced.
- Mineral and Rock Hunting: Many minerals and rocks exhibit fluorescence under 365nm UV light, making this flashlight an excellent tool for enthusiasts.
