Product Overview

The Pentair 523036 is the genuine 80-watt high-output replacement UV lamp for residential Pentair BioShield UV disinfection systems. The lamp produces the ultraviolet light that inactivates bacteria, viruses and chlorine-resistant organisms as water passes through the BioShield chamber.

UV lamps lose output with use even while they still light up. Replacing the lamp on schedule keeps your BioShield delivering the UV dose it was designed for.
