51g: The Weltool M6-UV is a penlight that uses a 395nm wavelength UV LED. The power of the output is below 0.5W which makes it more suitable for short distance use. The optical glass lens on the M6-UV presents a round and uniform spot effect. The light output ensures there is no dark area, no glaring centre spot and no stray light interference. The M6-UV runs off 2 x AAA alkaline or rechargeable batteries and offers runtimes up to 3.5 hours. The low radiations intensity is less harmful to the skin and can be used for DIY nail art, checking fraudulent documents and banknotes, checking oil leakage in small gaps, checking pet defecation and pet skin conditions. This pen light also features an easy to use tail switch and has a detachable pocket clip.
