Types Of UV Light - UV C, UV B, UV A   

UVC - shortwave UV, which includes germicidal ultraviolet at 253.7nm wavelength - is used for air, surface and water disinfection. Unintentional overexposure to UV-C causes skin redness and eye irritation, but does not cause skin cancer or cataracts.

The longer wavelengths UV described below are NOT produced by germicidal UV lamps. They are part of the complete UV spectrum produced by the sun.

UV-B - A small, but dangerous part of sunlight. Most solar UV-B is absorbed by the ozone layer. Prolonged exposure causes sun burn and could result in unhealthy effects on the skin and eyes.

UV-A - Long wave UV causes premature skin aging.
