UPGRADE UV LIGHT SOURCE- Made of high-quality light bead, with high power of 1300mW radiant intensity. The 365nm Light is a real invisible uv light that is not dazzling (DO NOT 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 or anti-counterfeiting codes, it will show obvious blue-violet light. FILTERED UV 365NM LIGHT- Designed with hard toughened black filter optical lens that can filter out unwanted visible light, and release invisible ultraviolet light, which is suitable for more professional detection needs. More Obvious Detection Effect - There is almost no disturbing visible violet light.
