OVERVIEW
The light that comes from the sun is energy and that energy is measured in nanometers. Only a small portion of energy from our sun is visible to the human eye. The ranges of 300 – 780 nanometers represent what we can see in the visible spectrum. Ultraviolet, or “UV” light, measured from the ranges of 100-400 nanometers is a range of light invisible to humans. To narrow the UV light range down further, within UV light there are different categories. Some of these categories are dangerous and we block them with sunscreens and sunglasses when we go outside.
We at UV Ray Lights are excited to introduce you to a newly recognized part of the UV spectrum called Far-UV. Far-UV’s nanometer range is between 207nm and 230nm and has been proven to be safe for humans while being effective against certain pathogens including coronaviruses
