A pond sterilization lamp, also known as a UV-C lamp, is a type of pond equipment that helps to eliminate harmful microorganisms and bacteria from pond water by exposing it to ultraviolet radiation. These lamps are commonly used in outdoor ponds to maintain clear and healthy water for fish and other aquatic life. Pond sterilization lamps can be installed as a standalone unit or as part of a larger pond filtration system. They are available in different sizes and wattages to suit different pond sizes and water flow rates.
