1 Powerful Pure UV 365NM Light With Filter -- Made of high-quality light bead rather than the diode lamp, up to 10W power consumption and 1300mW radiant intensity. Equipped with hard toughened black filter optical lens that can cutout disturbing spectrum, and release purer invisible ultraviolet light, nice for demanding detection. When it irradiates items containing fluorescent agents or anti-counterfeiting codes, it will show obvious blue-violet light. 2 Invisible UV 365NM Blacklight Flashlight -- It doesn't look as bright as 395nm. Almost no visible violet light, because it is invisible to human s eye. Ensure a more obvious effect.
