About This Item
The Pentair QuikPure3® 4-Pin Lamp (391270) is the OEM replacement lamp for the QuikPure3 ozone system, serving both the 25,000-gallon and 50,000-gallon configurations.
⚠️ IMPORTANT: CONFIRM YOUR SYSTEM DESIGNATION BEFORE ORDERING
This lamp carries the designation "1-25 or 2-50," indicating it is used as a single lamp in a 25,000-gallon unit or as one of two lamps in a 50,000-gallon unit. Verify your QuikPure3 model number before ordering to confirm the correct quantity for your installation.
The 4-pin lamp is the light source at the core of the QuikPure3 ozone system. As the lamp ages, output diminishes and ozone production declines — reducing the system's ability to oxidize contaminants. Replacing the lamp on schedule restores the system to full oxidation capacity. Match part number 391270 to the lamp currently installed in your unit before ordering.

Pro Tip
UV lamps in ozone systems degrade gradually — output drops well before the lamp visibly fails. Most manufacturers recommend replacing the lamp on a fixed annual or hour-based schedule rather than waiting for visible failure. Check your QuikPure3 installation manual for the recommended replacement interval specific to your unit. If your system serves a 50,000-gallon installation (models 381250 or 383201), note that two lamps are required — order accordingly.
