Product details

The Pentair 523038 is the 150 watt replacement UV lamp for BioShield UV sanitizer models 522638 and 522945. It is the genuine Pentair part, sized and rated for those two units.

Why the lamp gets replaced

A UV lamp keeps glowing long after its germicidal output has fallen off, so a BioShield that looks like it is working can be doing far less than it should. Replacing the lamp on schedule keeps the sanitizer inactivating what it was installed to handle.

Before you order

Confirm your model number. The 522638 and 522945 take this 150 watt lamp; the smaller 522637 takes a 120 watt lamp. While the housing is open, check the E150S quartz sleeve for clouding or cracks, since a fouled sleeve blocks UV as effectively as a tired lamp.

Questions and answers

What people ask about this product, answered by our pool techs.

Which BioShield units does this lamp fit?
The 150 watt lamp is for BioShield models 522638 and 522945. The 522637 uses a 120 watt lamp, which is a different part.
Is this a genuine Pentair lamp?
Yes. Part number 523038 is the Pentair replacement lamp for these BioShield models.
Should I replace the quartz sleeve at the same time?
Not always, but look at it while the housing is open. If the E150S 65 in. sleeve is cloudy, scaled or cracked it will block UV and should be replaced along with the lamp.
How do I know the lamp is due?
UV output drops with run time before the lamp actually fails, so follow the replacement interval in the BioShield owner's guide rather than waiting for it to go dark.
