If your PUR water purification system needs a UV lamp replacement, this LSE Lighting equivalent is exactly what you're looking for! This 60-watt UV lamp produces that crucial 254nm wavelength that effectively neutralizes bacteria and viruses in water systems. The 24-inch length and 4-pin base (all pins on one end) match the specifications of PUR PUV25H systems perfectly. With an operating current of 800mA and high-output design, it delivers the same performance as the original equipment lamp. Manufactured in an EPA Registered Establishment (No. 96823-PA-1), so you know it meets regulatory standards for quality and safety. Important safety note - always use proper safety gear during installation, including gloves and eye protection, since you're handling glass and dealing with UV light. This is an equivalent replacement bulb, not an actual PUR brand product, but it's fully compatible with systems designed for the PUV25H lamp. When your current UV lamp reaches the end of its service life (usually around 9-12 months of continuous use), replacing it ensures your water purification system continues to provide effective protection against microorganisms. The installation is straightforward if you follow proper procedures - just make sure the system is powered off, handle the lamp carefully to avoid fingerprints on the glass, and ensure proper alignment when inserting. Maintaining your UV purification system with timely lamp replacements is crucial for ensuring your water remains safe and clean for consumption.
