Viqua 602805 UV Lamp

Description

The Viqua 602805 UV Lamp is a genuine germicidal ultraviolet (UV-C) replacement lamp designed for select Viqua and Sterilight ultraviolet water disinfection systems. This lamp is engineered to provide consistent UV output at the germicidal wavelength, ensuring your UV system continues to inactivate bacteria, viruses, and other waterborne pathogens — helping deliver safer, cleaner water without the use of chemicals.

Replacing the UV lamp at recommended intervals is essential for maintaining validated performance and effective disinfection even if the lamp still emits visible light.
