Smart lights have up to 16 million RGB colors to choose from. So you can illuminate the different rooms in your home with the light you need for each moment, without having to change the bulbs.
Smart lights have the same size and thread as old-fashioned lamps, so they fit into any lamp socket without the need for conditioning.
In addition to working with motion sensors, they are an interesting alternative when there is no one at home. You can configure them to turn on and off at certain times of the day, so it will seem that the house is still occupied.
