Pool is still being built - no gunite yet - so "built into" system would be preferred. On one side of my pool we have a raised wall area. It's going to be a weeping wall with water spilling down the side. On the coping above that wall I'd like to have light that shines down on the wall.
I'm not particularly looking for suggestions on the lighting itself - I've done a lot of research and from what I can see there is 1) Approved Fiberoptic Lighting and 2) Technically not approved, but still used by some Waterproof Low Voltage LED Strips
What I'm wondering is if there is anything that exist that could be installed as part of the construction gunite/coping part of the build to that wall that would serve as track on the underside of the coping to which I could later install whatever lights I wanted to. Then I could decide later, especially because if we go the Fiber-optic route ultimately, we could not afford it now. But of course now would be the only time to have some type of track built in so we don't later have to figure out how in the world to attach lights to the bottom of the coping.
Here's a render of what the wall is like at day and night:


Any suggestions on mounting brackets that could be built in would be appreciated.
