Most children enjoy falling asleep with the lights on. This often results in the lights being fully lit until one of the parents notice the child sleeping and turns the lights off. A situation like this not only force parents to keep looking after whether the child is sleeping or not, it also contributes to the electricity bill.

With a controller and a lighting plug with a dimmer function a better way is possible. The lights can be dimmed over a certain period of time and eventually be completely truned off. This results in more liberty to the parents while giving the child a safe and calm atmosphere to fall asleep in.
