365nm UV Flashlight Rechargeable Black Light Powerful Ultraviolet LED for Curing UV Glue Detecting Minerals Diamond Scorpions and Leak Detector

If you want maximum effect from "black light" reactive items, 365nm is the best wavelength for this. Ultra-low "visible" light emission shines at a wavelength of 365nm- ensures the stain, not the surface, is illuminated. The 365nm light will appear white on neutral non fluorescent surfaces, where as the 395nm will appear purple. This flashlight produces a near pure UV output which is the optimum frequency for UV fluorescence. 365nm is well beyond the visible spectrum, so it can produce clearer florescence, cleaner more vivid colors, and no violet glow. 395nm is less expensive and can work perfectly well for detecting urine and bodily fluids in the dark, but for document verification, counterfeit detection, photography, and other specialty applications 365nm is a much better choice. Warm tips: Please clear your needs before ordering. 365nm Ultraviolet LED light is invisible to the naked eye, so that it is not as BRIGHT as the 395nm flashlight, but more perfect for detection of high demand like fluorescent agents & security code. 365nm flashlight is not recommend to detecting pet urine stains. it’s important to know that UV light is not visible so when you're shining it on non-reactive surface it does look dim which is a good thing. It needs an 18650 Lithium Ion battery, so you have better to get a battery and charger.
