How Does UV Light Kill Germs?

Over 140 years ago Downes & Blunt discovered the antibacterial effects of sunlight. Determining that shorter wavelengths of the solar spectrum were more effective at neutralizing bacteria. It is now widely known that there are substantial germicidal and anti-bacterial effects from UV-C, UV-B, and UV-A  spectrum. 


DNA & RNA is the genetic material that makes up all living organisms, controlling their growth, development, functioning and reproduction. UV light produces electromagnetic energy that can destroy the ability of microorganisms to reproduce and by causing photo-chemical reactions in nucleic acids (DNA & RNA). The ultraviolet energy triggers the formation of specific thymine or cytosine dimers in DNA and uracil dimers in RNA, which causes inactivation of microbes by causing mutations and/or cell death and failure to reproduce.

Broad Spectrum of Light Optimizes Effects

Enertech's product lines, powered by Violet Defense technology, represent a significant breakthrough in germicidal protection for the world. Our UV lighting uses a powerful, broad spectrum light, including germicidal UV-C, UV-B and anti-bacterial UV-A to optimize their germ-killing efficiency.

UV-C is most traditionally referred to as germicidal UV with the ability to kill bacteria, viruses, mold, and fungus.

UV-A and UV-B light causes oxidation of proteins and lipids causing cell death.

Broad band UV lamps have also been shown to inhibit photo-reactivation, the process that can result in self-repair of damaged microbes.
