I have a 20x40 in-ground vinyl lined pool. The pool was installed with no lighting of any sort, making night swimming impossible. I have considered a few options to remedy and looking for any feedback you all may have.
The first would be installing submersible LED "puck" lights, suctioned to the walls with a remote control. There are many for sale online that claim to be waterproof and run on AAA batteries. I have my doubts of their longevity, brightness, and durability in chlorinated water.

Second would be installing LED rope lighting around the perimeter of the pool, either along the coping, or possibly under water. I have a suspicion under water is not a great option. Issues with this are: finding a long enough strand of lights for a large pool and looking like casino with a bright strip around the top and the water still relatively dark. My coping does not overhang the pool, so it would literally be right on the wall. Also, IP68 rope lighting seems difficult to find.
Lastly, I found this "nicheless" light from PAL PAL Lighting Evenglow Multi-Color Nicheless LED Pool & Spa Light | 7W 12V 80' Cord with Plug | 64-EGN-80 that appears to simply screw into any standard 1.5" wall fitting. I happen to have an unused wall fitting that went with a now-obsolete jet cleaning system (we use a Dolphin now). I have that port blocked off, but the pipe leads right back to my pump area where power is available. I am curious if anyone has tried a retrofit such as this and if it worked out. I am also curious if the 7W bulb would be adequate to light a 20x40 pool.
Any and all thoughts are welcome and thank you in advance!
