A Pentair IntelliBrite 120V 55w light was installed. The original pool light that was 35 yrs old (not working) was there, and I told them I wasn't sure of the voltage because the light hasn't worked in 20 years and someone should test it before they install it. Well they said it's probably a 120V and thats what they ordered. When the workmen were here I asked them 3 times to test it first and they put it in and said the light is fine and I just need an electrician. They ran a cord from the transformer under the diving board to the electrical outlet on the deck and it worked, which my electrician informed me shouldve been the indicator right there that it needed to be 12V and they shouldve known that, I'm mean I'm clearly no expert on pools or electric. The Electrician confirmed it should've been a 12V light installed. I waiting for the Pool company to call me back. I'm just wondering how big of a deal it is for them to change it out- is it a giant hassle or just a matter of unscrewing the lid and replacing one thing with another?
