My father is a double amputee. I have the system and set him up with one as it allows him to turn on and off lights he normally could not access. It's impressive, lights with wireless chips that can be any color, turned on/off from your devices or system(s), automating lights to come on in groups, certain times, specific colors, and now geofencing and allowing lights to slowly come on based on daylight savings are great features. Keeping in mind, these are LED lights, combined with tailored control, will save money over time.
