The differences between the various wavelength of the lights is that the 365nm light has less visble light and more UV light than the 385nm light. Risk Reactor’s 390 nm lights have the least UV and most visible light. The 400nm light is closer to the human visible range and was designed for hunting scorpions along with UV responsive minerals

How to Use:
Simply press the button and the UV LED fires up. Point the UV LED light on fluorescent material to make it glow. You can also use this to charge glow in the dark products such as paint and pigments.

Forged document detection:

Risk Reactor’s special purpose UV black lights produce a powerful beam of ultraviolet light, which will activate fluorescent invisible and visible inks, strips, & fibers that are used as anti-counterfeiting measures in bank notes, credit cards, casino chips, passports, checks, securities, cryptographic papers, and many more. Our keychain UV lights are also great for checking fluorescent hand stamps at clubs, curing UV-sensitive glue and many other uses. The keychain UV LED beam has a fairly narrow focus and unlike a traditional blacklights, most of the light produced by the BKEY365 UV LEDs is just outside the visible spectrum of light (BKEY365 has 365 nm). The BKEY is 390nm and the B4KEY is 395-401nm.
