Need a new light fixture. Should I switch to 12v?

Basically, the title says it all. Have an old Amerilite 120v fixture and it has some corrosion around the base from a leak where the cord inserts. The housing flooded and took out my LED light. I'm definitely going with another LED, either another Florida Sunseeker, or a J&J (have read good things) but should I go with the 12v instead of the 120v? I'm assuming it's safer, but I would have to figure out how to install the transformer since my current light cord comes up a conduit into black junction box that's about 12" off the ground. Thanks for any insight.

If you do it, remove the junction box, install the transformer there, it will act as a J-box. What size conduit do you have?
A 12V light uses a larger cord than a 120V and it is hard to pull through the 3/4" conduit that some pools have.
As has been said, 120V with a working GFCI, is as safe.

That's good to know I had no clue about the wire size. the conduit is definitely 3/4" so I'll stick to the 120v versions to make pulling the wire easier.

This is what I am working with:

I was looking at this light since I need both the housing and the bulb and this would be cheaper with no leaks.


They state that every light is 12v and comes with a transformer. How would I install a transformer with a J box like this?

If you open that box, you will probably see that the light cord is coming up through the 1" conduit at the center and the electric supply is entering at the 3/4" on the end. That gives you options.

It says 12 or 120 volt.

Is the extra ground secure in the niche?

Please, if you are not familiar with working with this type of electrical appliance, get a pro. You are mixing electricity, conductive water, your family.
This is from the website:

We also offer a smaller version designed to fit inside existing junction boxes, this version is very small, dimensions (inch):
H = 1.31, W = 1.62, D = 3.4 and fits into most standard junction boxes, if you prefer the smaller internal version just let us know:

That is the most standard of standard pool-light junction boxes in your picture.

Pool Light transformers need to conform to UL 379 (Pool, Spa and Fountain Power Unit Standard) and be "Listed".



UL 379
Power Units for Fountain, Swimming Pool, and Spa Luminaires


1.7. TRANSFORMERS AND POWER UNITS
General. Products Listed in this category are enclosed transformers and DC output power supplies.

They are intended to supply luminaires in fountains, swimming pools, and spas in accordance with Article 680 of the NEC®.

The primary rating is 120 volts and the maximum secondary rating is 15 V rms or 30 Vdc and 1 kVA.

Listing Mark. The UL Listing Mark for these units includes by the product names “Fountain Transformer”, “Swimming Pool Transformer,” “Spa Transformer,” or “Fountain, Swimming Pool or Spa Transformer”, “Fountain Power Unit,” “Swimming Pool Power Unit,” “Spa Power Unit,” or “Fountain, Swimming Pool or Spa Power Unit.”

Special Markings:

Swimming Pool Junction Box Use.

Unless marked otherwise, these transformers are not suitable for connection to a conduit which extends directly to a wet-niche or no-niche luminaire.

Transformers not suitable for this use are to be used with a swimming pool junction box.
