Let there be light, and there was light, and the light was good.
My lights are spaced at 1.3m centres, which gave me an equal distance between each corner and the first and last light. The fence is 1.8m high and the lights are about 70mm from the top of the fence. The gap between the feather edge boards is 100mm so the lights fit perfectly centered on each face of the board. I used a 100x100mm off cut of feather edge board behind each light fixed the opposite way round. In so doing the lights face directly into the garden and not at the angle of the feather edge boards 👍.
