context_page_description: A germicidal lamp is an electric light that produces ultraviolet C light. This short-wave ultraviolet light disrupts DNA base pairing, causing formation of pyrimidine dimers, and leads to the inactivation of bacteria, viruses, and protozoa. It can also be used to produce ozone for water disinfection.
  There are four common types available:
  Low-pressure mercury lamps
  High-pressure mercury lamps
  Excimer lamps
  LEDs
