What Is UV-C Light?

UV stands for ultraviolet light. Ultraviolet light represents the frequency of light between 100 nanometers (nm) and 400nm and cannot be seen with the naked eye. Within the UV spectrum lie three distinct bands of light: UV-A, UV-B and UV-C.
  • UV-A (400nm-315nm): The long wave UV light (315nm to 400nm) or UV-A refers, to what we commonly call “black light.” This is the longest wavelength region and has the lowest energy. UV-A represents the largest portion of natural UV light.
  • UV-B (315nm-280nm): The UV-B (280nm to 315nm), or mid-range UV, causes sunburn.
  • UV-C (280nm-100nm): The germicidal UV light (100nm to 280nm), or UV-C, is effective in microbial control.
Scientific research has proven that the most effective frequency for microbial destruction is between 280nm and 200nm, which is within the UV-C band. Therefore, as long as the nm frequency of a germicidal lamp is well controlled within that range, the microorganisms will be destroyed effectively.

Please note: Opportunities for infection are abundant and virtually everywhere, so it is important to realize that use of the Travel UV Sanitizing Wand does not guarantee that the user will avoid illness. To avoid microbial infection, one must take a wide range of precautions. Use of the VeriClean™ UV Sanitizing Wand is an important precaution, but not the only precaution that one should take.
