I need to install 4 lights in the base level of a large fountain. There is already 12ga wire prewired in with the pump wires. I plan to install 4-10w mr 16 lights as its very shallow and from what i can see the par lights just wont fit. How do you guys go about making an underwater connection vs your regular buried connections. Right now I solder and grease tube or use dry-cons for my connections with zero problems.
