That's a cheap Wyze security camera pointed off the top deck at my 3 lights on a Sea Isle canal, with some neighbor lights off to the side. I added the 3rd light yesterday, the 3rd from the left. I've been experimenting with some home made 12V lights to see how they compare to a commercially available (and $$$) 120V high intensity lights. That's part of the reason for the camera...
The left most light is a 12V light, and so is the new one (3rd from the left). The one between them is a 120V light. The 12V lights burn 50-60 watts each, while the 120V light burns 275 watts.
The leftmost light has been in the water around a year. I have to pull it every 2-3 months to clean the algae off it, because it doesn't get hot enough to burn the algae and barnacles like the 120V light. But that's easy- just pull the wire, scrape it off and throw it back. It's epoxy encapsulated LED, so it doesn't break like the glass 120V bulbs.
I started experimenting with 12V LEDs after a boat ran over our glass bulb, and a fisherman snagged the wire on our neighbor's 120V light, both times resulting in $200+ service invoices. I also don't like the idea of running 120V where the kids are swimming and kayaking, even if we do have GFI.
Probably a lot more than anyone wanted to know, but I'm pretty pleased with the results...
Edit: On an aside, I took a smaller (20 watt) LED light, mounted it under a boogie board on a 50' wire, and I can pull it behind my kayak with a small 10A-Hr battery lasting pretty much the whole evening. It's already pretty bright, but this week I'm adding a silver mylar sheet between the board and the light to see if that increases the circle of light.
