This high-output UV sanitizer bulb operates at germicidal wavelengths designed to help reduce bacteria, viruses, algae, mold, and other microorganisms commonly found in spa water. UV-C technology works by disrupting the DNA of microorganisms, rendering them unable to reproduce while helping maintain cleaner and clearer water without affecting water chemistry.

The updated ClearRay® XL replacement bulb provides approximately 20% greater water contact and up to 40% higher UV output compared to the original 6472-857 design, while maintaining direct compatibility with existing systems.
