Kaito V5-DB UV Flashlight 395nm 10W USB-C Rechargeable

Compact UV 395 nm Tool

The Kaito V5-DB is a pocket-sized ultraviolet flashlight built around a 10 W LED that emits at 395 nm with 1300 mW radiant intensity. An aluminium body measuring 3.5 by 0.85 inches and weighing 57 grams houses a USB-C rechargeable cell. A full charge takes one hour and delivers one hour of continuous output. A red indicator on the tail switch warns when power is low, and a lanyard allows one-handed carry.

Detection and Curing Tasks

This light suits hobbyists who cure UV resin, identify fluorescent minerals or locate dried pet stains on fabric and carpet. Gem collectors checking uranium glass or amber will find the wavelength effective. Users needing water resistance, longer run-times or a wider flood beam should look at other designs because the aluminium shell is not sealed against moisture and the battery is fixed at one hour.

395 nm Wavelength Decides Fit

The single specification that determines suitability is the 395 nm peak wavelength paired with 1300 mW output. Materials that fluoresce strongly at this wavelength — such as certain resins, security inks and biological stains — will be clearly revealed; substances requiring shorter or longer UV bands will not respond.
