Impeccable pilot for a child's room. I took the blue and white, and I have chosen to keep the white (dimmed light for blue) White allows my son (4 years) night not to be afraid, to be appeased only after a bad dream, to find cuddly toy and pacifier, and get up only to go to pot placed at the foot of his bed By opening his eyes for half clock micro and view only his room, his world it reassures immediately. No more screams calling mom, dad at night, with the long minutes that accompany awakening to try to tranquilize. The light is not anything embarrassing to sleep. It allows him to make his full night plus waking, weeping, he is now reassured. This one goes out only when the sun rises. It can remain connected continuously. Do not heat. Very convenient.
