I am presently in the works of building my own concrete pool and was wondering what are the best/affordable light niche for both the pool and the spa area. I am assuming the pool will have 2 large lights and the spa smaller lights. I was going to use a custom made LED bulb (in order to incorporate it into my home-automation) so I was looking for niches that can use a replaceable bulb that can be modded.
