Rayovac 395nm UV Keychain Flashlight 6 Pack

Portable UV Detection Kit

This six-pack supplies 395 nm ultraviolet keychain lights for quick fluorescence checks on documents, currency, stains and pet messes. Each unit weighs 0.29 ounces and measures 0.32 by 1.2 by 1.46 inches, so the set fits in a glove box, tackle bag or nightstand drawer. The 12 lumen output is tuned for close-range inspection rather than area lighting. Buyers who need a wide-beam torch or long-throw UV flood should look elsewhere.

Two-Mode Operation & Battery Swap

Activate momentary light by pinching the centre of the body, or slide the side switch for continuous 12-hour runtime on the installed CR2016 cells. Replacement requires prying open the plastic housing; the small tabs can snap if forced, so work on a flat surface and keep the tiny screws together. The lights are not water resistant, so dry them promptly if they get damp. Users wanting rechargeable cells or a sealed body will not find that here.

Compatibility Check Before Buying

Verify that 395 nm wavelength suits your target materials; some security inks and minerals fluoresce better under shorter or longer UV bands. Confirm you have a small Phillips driver for the battery compartment and a supply of CR2016 spares for extended trips. The key-ring loop accepts standard split rings but may not clear thick carabiners or heavy-duty lanyards. If your application demands submersion proofing or hands-free head mounting, this form factor will not meet the need.
