UV (400271) Lamp (Bulb)
UV Lamp 400271
The UV Lamp 400271 is a replacement bulb engineered for continuous ultraviolet disinfection in residential and light commercial water treatment systems. This lamp emits UV-C light at 254 nanometers, the wavelength proven to disrupt the DNA of bacteria, viruses, and protozoa without adding chemicals to your water. Regular replacement maintains disinfection performance as lamp output degrades over time.
What Makes This Lamp Essential
UV-C Output
Emits germicidal 254nm wavelength light that targets microbial DNA, preventing replication and rendering pathogens inactive
Direct Replacement
Factory-spec'd for Isopure UV systems using model 400271, ensuring proper fit and electrical compatibility
Annual Service
UV lamps lose intensity over 9-12 months even while still glowing; timely replacement maintains disinfection efficacy
Chemical-Free
Provides microbial reduction without chlorine or other disinfectants, preserving water taste and eliminating chemical byproducts
System Compatibility
This lamp is designed as a replacement component for Isopure Water ultraviolet disinfection systems specifying part number 400271. Verify your system's lamp model before ordering, as UV lamps vary by wattage, length, and base type. Commonly used in whole-house UV systems, point-of-entry disinfection setups, and well water treatment configurations where microbial contamination is a concern. Check your UV system manual or existing lamp markings to confirm compatibility.
Isopure Water sources components from verified manufacturers to ensure your water treatment system performs as engineered.
