Whilst you can buy outdoor smart lighting, we prefer to use stylish external light fittings designed specifically for outdoor use and then make them smart. This is not only much cheaper but it also gives you many more options in terms of power, control and aesthetics.
Our front garden lights are a good example of how we can use any 'dumb' lighting connected to our contextual smart home, to make it really smart. We didn't like being restricted to using existing smart lighting products on the market, so we choose high quality, stainless-steel lamps which we integrated into composite fence posts. These are 12V dc wired lamps. The lamps and wiring have been hidden within the posts.
