DARKBEAM UV Flashlight Black Light 365nm Woods lamp, USB-C Rechargeable Filtered Blacklight, LED Ultraviolet 20W Powerful Handheld Detector for Pet Urine, Mineral, Fluorescent, Resin Curing HammerHead Showers Note:With a DC voltage rangeAbout this item UPGRADED 4 CORE UV LIGHT BEAD Made of upgraded 4 core light bead, with high power of 20W and 480mW radiant intensity. The 365nm Light is a real invisible uv light that is not dazzling (DO NOT ALWAYS LOOK DIRECTLY AT UV LIGHT!). It doesn't look as bright as 395nm because it is invisible to the naked eye. But, when it irradiates items containing fluorescent agents, security code or watermark, it will show obvious blue violet light.
