Jacuzzi® CLEARRAY® UV Bulb FAQs

Jacuzzi® recommends replacing the UV bulb approximately every 12 months. The bulb may still produce visible light after one year, but its effective UV output gradually decreases over time.

This genuine OEM CLEARRAY® XL replacement bulb is current part number 6472-841. It replaces the earlier OEM bulb part number 6472-857.

This bulb is compatible with most Jacuzzi® spas manufactured in 2012 and newer that use the CLEARRAY® XL Water Purification System. Compatibility can vary by model and production year, so contact us with your spa model and serial number if you need help verifying the correct replacement.

In most cases, no. The spa generally does not need to be drained when replacing only the UV bulb. Draining may be necessary when removing, cleaning, or replacing the quartz tube or related seals.

Avoid touching the glass with bare hands. Oils from your skin can remain on the bulb and may shorten its service life. Handle the bulb by the ceramic ends or wear clean gloves during installation.

Visible light does not necessarily mean the bulb is still producing full-strength UV output. The effective UV performance gradually decreases with use, which is why annual replacement is recommended.

No. The CLEARRAY® system supports water sanitation, but it does not eliminate the need to maintain an appropriate sanitizer level and balanced spa water. Continue following the water care instructions provided for your Jacuzzi® hot tub.

It is a good time to inspect the quartz tube, seals, O-rings, wiring connections, and surrounding components for mineral buildup, moisture, or visible damage. Always disconnect power before opening or servicing the CLEARRAY® system.
