1) UV-C basic information
What is UV-C?
Ultraviolet (UV) light is invisible to human eyes. It can be subdivided into three categories:
•
UV-C from 200 to 280 nm - For disinfection purposes and germicidal application.
•
UV-B from 280 to 315 nm - For medical use (i.e. phototherapy to treat skin conditions, including
psoriasis).
•
UV-A from 315 to 400 nm - For use with curing, suntanning and insect traps.
How does UV-C work?
•
UV-C radiation can break the DNA and RNA of bacteria, viruses and spores, meaning that they
leave them harmless. There are no known micro-organisms resistant to UVC.
•
UV-C technology has been used safely and effectively in hospitals and governmental buildings
for more than 40 years.
•
Most UV-C solutions utilize conventional lighting, with LED now improving in efficiency.
•
The peak output of our germicidal lamps (253.7nm) is close (80-85%) to the maximum
effectiveness of UV-C (265nm).
•
Smaller UV-C wavelengths (222nm) are being explored as less harmful alternatives.
