UV LED Flashlight Torch

Several customers have asked this question, UV led flashlight use wavelengths to distinguish effectiveness of the flashlight, 395 and 365 wavelength uv flashlight effect will certainly vary, but there is no flashlight can control wavelength of the light. Now introduce 365 wavelength of a uv flashlight.
365nm only some weak white light , in general, very little visible light , almost all kinds of authenticity products can use it , 365NM brightness , although weak, but the fluorescence effect is very clear , because the UV small flashlight is a special light source , please use it under low light environments,to have the ideal effect! Uses : Check fluorescence reaction gemstone .
1. Help category . Some gem on color appearance relatively close, but the fluorescence reaction yet obvious differences, can make use of ultraviolet fluorescent to points it out . For example : ruby and garnet , some green mother green, and green glass, sapphire and blue cone ore . The results are not the same

2. To help judge repair or bonding. The ceramic has no fluorescence under ultraviolet,if a certain part of porcelain emerge fluorescence under ultraviolet, you should consider whether or not patched , because the patch need to use glue, and most of the glue will fluoresce under ultraviolet : Some stick gem's stick place will also fluoresce , because they may also use the glue so it is important to identify such things ! Such goods are not suggest to buy,no fluorescence under ultraviolet gem does not have identification significance

Use UV torch to check cosmetic, the fluorescent scared shit out of me. Ms Chan who living in Xiaoshan used to do face and back care at a Beauty club called ”Duofang”, and has costed 25,000 in there.
