Led germicidal lamp UVC 260nm 270nm 280nm ultraviolet disinfection  lamp

       Studies have shown that uv is mainly based on the microbial spores (bacteria, virus and other pathogens) of the radiation damage and damage the function of the nucleic acid kill microorganisms, so as to achieve the purpose of disinfection ultraviolet radiation on the function of nucleic acids can lead to broken strands of key and chain between crosslinking and photochemical products, etc., which changed the biological activity of DNA, the microbe itself cannot be copied, this uv damage is also fatal injuries

How many time dose it need to kill bacteria?

       It takes anywhere from a few seconds to a few minutes, depending on the type of bacteria.
