Will this unit fit in a Hayward niche?

A  Answered on 6/11/2016 by InyoPools Product Specialist Lennox H.

Hi, This light can fit in selected Hayward niche but to ensure proper grounding and bonding you have to use a Hayward light with a Hayward niche.

Does this light come with a cord stopper? If not, what is the cord diameter so I can buy the correct stopper. Thx

A  Answered on 6/12/2018 by InyoPools Product Specialist Lennox H.

Hi. A cord stopper is not included. The Cord is 3/4" which requires Item # Q-CS5

Hi, Roland. This fixture does not have a built-in transformer, the Intermatic 300 Watt Transformer - PX300 is required.

Light # 78438100, do I need anything else to replace my light with this one. Gasket, seal or transformer

A  Answered on 5/9/2020 by InyoPools Product Specialist Patrick P.

Hi Fred, If you are replacing the complete light assembly then this should be all you need.

Hi, My old pool light has had a leak and the base is rusted. So I was looking for a replacement fixture and found this out. The old fixture is an American Products fixture 12V, 300W (the label says series 7883XX, 7843XX). My question is, will this fixture be the correct replacement for that? Also, can I use an LED multi color bulb with this fixture instead of incandescent bulb? If so what would be a compatible bulb? Thank you for your help.

As long as 50' of cord is enough for the installation, yes, the Pool Amerlite 300 Watt 50 Ft Cord 12 Volt - 78438100 is correct. The ColorSplash LXG LED Pool Lamp 12V - LPL-P2-RGB-12 with Guardian Silicone Lens Extra Heavy Duty Gasket for Pentair Amerlite - LPL-G-P will be needed for the install and use with the LED Color bulb.

I wanted to replace my current pool light with a 12 volt pool light

Written on 6/15/2020 by Guest

After installing the Intermatic 300 watt transformer and the light niche, I needed to replace my old pool light. Luckily, my pool was already drained because I was replacing the liner and the previous pool light was already taken off. Therefore, all I had to do was run the wire of the pool light to the transformer, add some epoxy putty and screw the light on. It was a piece of cake.
