Does anyone have any experience with these particualr lights? http://www.hooverfence.com/vinyl_fence/low-voltage-cc-caps.htm I have to replace the railings on our front porch. I will have 6 white vinyl half heigth posts that I want to put lights on top of. There will also be 5 full height posts. I tried to sketch this in "paint" but I'm no artist. There will also be two half height posts where the end railings turn back and meets the house. This drawing is not to scale, the distance between the full posts to the left of the door is about 11 feet each. Is there a better light for this?
