Hope this comes out right. I'm wanting to light the underside of a boat dock. The dock has a 2x4 say (skirt) around the entire dock. There are 5 2x4s down the side. The last 2x4 is right at the waters edge. I think it would look cool IF there was some light behind that (skirt). The fixture would be mounted on the underside of the decking on the dock, pointing to the water. I'm having a hard time trying to figure out what fixture to use. Has anyone done this before? If so do you have any pictures? The other wild thought is has anyone took an underwater light and mounted it to the post of a dock? Say 2-3ft below the water.
