I'm posting this to a new thread to avoid confusion with a similar thread (many thanks to those who responded);
I have had a Pentair SAM light for many years and it has leaked through the bushing where the cord enters the fixture 3 times, each time requiring a replacement seal around the lens, and a color-wheel motor. This time the leak finished off the light, and I need a new one. I am probably going to re-use the existing niche and install a new Pentair Intellibrite LED light.
Some online user experiences I have read left me concerned that the Intellibrite follows the same design as the SAM, and the leakage problems as well.
I have heard there are many ways to enhance the seal around the cord bushing before installation by using something like butyl tape, AB Putty, RTV silicone, etc. I am looking for suggestions on the best sealant that I can apply to the cord entry point.
