Rechargeable 365nm UV Flashlight, Ultraviolet Torch with Blacklight Filter for Curing Resin/Oil Leaks on Rocks/Minerals

Professional 365nm UV Lamp: Adopts a 5W LG 365nm UV LED with a shorter wavelength. UV flashlights are becoming professional-grade for certain users. 365nm ultraviolet light is not visible to the naked eye, so it is not as bright as a 395nm ultraviolet lamp. Please consider your needs before ordering. Size: 135x27x27mm. Black UV Filter: Equipped with a robust black filter optical lens, it filters out ambient light and blocks visible light, but allows 340-380nm UV rays to pass through. This method reduces interference with visible light. USB Rechargeable Flashlight: Built-in 1200mAh rechargeable battery with Micro USB charging cable and output port. It can be used as a power bank in emergencies. Charging is indicated by a red light, and a green light indicates a full charge. There is no need to buy or find a separate battery.
