I have a Pentair 7883xx series inground vinyl liner pool light fixture . Want to replace the entire fixture with a multi color replacement led fixture any suggestions

A  Answered on 6/1/2021 by InyoPools Product Specialist Patrick P.

Hi Robert, We show that the 7883xx is a 12V 300 Watt light, you may want to double-check just to confirm. If so then I would suggest this J&J LED Light Fixture Replacement this is the complete light fixture with color-changing LED bulb that will fit into your current niche. This light comes with 100' of cord and is in stock.

A  Answered on 5/1/2021 by InyoPools Product Specialist Patrick P.

Yes a Pentair Intellibrite color LED Spa light (640131) will fit into this niche.

Can you tell me what kind of seal goes on the back of the niche to seal the cable that goes through the niche?

A  Answered on 12/1/2020 by InyoPools Product Specialist Hector F.

Hi Sheldon, those seals are unfortunately not replaceable as they are fabricated with the light fixture itself. This is likely due to code requirements.

We currently have multiple Pentair Spabrite # 78109100. With current situation, spa have been drained for awhile and the gaskets are bad. Can I just order gaskets and what would the part be. The niche is #78242300.

A  Answered on 4/3/2020 by InyoPools Product Specialist Patrick P.

Hi Shawn for your SpaBrite Light you will require this SpaBrite Lens Gasket we would also suggest getting some of this Gasket Lubricant which will prevent your gaskets from drying out and cracking.

Last week I purchased your Pentair SpaBrite light fixture 78106200. When I went to install it I noticed that my Pentair Niche 78241xxx/78242xxx has a metal tab on the top that the light fixture screws into is broken. Do I need to replace the niche? I think so because I don't see how else I can connect fixture as that is a grounding screw for the fixture. This would be going into a fiberglass pool/spa. I am trying to replace my spa light with the correct parts.Thanks for your guidance.

A  Answered on 6/9/2017 by InyoPools Product Specialist Patrick P.

Hi Greg, you would not want to replace the entire niche as this would be a major construction project. I would suggest this Light Wedge Repair Kit which is designed for your exact situation where the tab on the light niche breaks off.

The ss ring that the pilot screw goes into is broken. Can I just replaced that ring or do I have to replaced the whole Niche? Can I buy just the ring?

A  Answered on 5/25/2016 by InyoPools Product Specialist Patrick P.

Patrick, Is this for a small spa light or a larger pool light? This will help us determine the correct part for you.

What is the difference between a niche and a light?

A  Answered on 10/8/2013 by InyoPools Product Specialist Patrick P.

A niche is a housing that is permanently mounted in the pool wall, while the light is a “fixture” that is secured into the niche.
