Part # PL5851

Manufacturer Code 79101600Z

Product Description

PureLine PL5851 8-1/4" replacement lens gasket is an After-Market Gasket for the Pentair Amerlite and SAM lights.  Replaces the OEM lens gasket 79101600.

The lens gasket provides a seal between the face ring and glass lens to prevent water from getting inside the fixture.

It is strongly recommended to replace the lens gasket when replacing a pool light bulb.  Over time, use, heat, and chemicals will compress the gasket and can cause it to fail.  A light bulb change is the perfect opportunity to replace this very important seal.

This would be the proper gasket and you will need this PureLine PureColors 12V LED Color Changing Bulb

Yes, do you have any candelabra bulbs for a pentair pool light?

At this time there are no LED's that will fit in a Candelabra based unit.

Hi Bob, Unfortunately there is not a replacement LED bulb for the T4 bulb type. You would need to replace the complete fixture with this Amerilite Light Fixture and this 120V 35W PureColor LED Bulb
