- 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.
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 Veri Clean UV Sanitizing Wand is an important precaution, but not the only precaution that one should take.
