We have all seen them; you see them in films, you see them on television shows and you definitely have seen them in adverts. Automatic lights. They seemed so futuristic; people would come into their homes, into their kitchens, and one of two things would happen. The first is that the character would clap their hands and the lights would come on, lighting the room up in an instance. The other is that the lights come on automatically, much like those that people use to light up their front doors when they arrive home at night.
But why didn’t they catch on in the home? The truth is the fantasy looks much better than the reality; the lights are unreliable, any movement triggers them on, and the clap lights can turn off in a heart beat (or even any sound that sounds a bit like a clap.) Plus they are very expensive to install.
