We have installed the dimmer in the nursery and operate it with a 60W light bulb. If the light is off and you palmed it you have to walk 1/4 turn make (to what happened) and the light will jump to 40% performance IMMEDIATELY, so we usually have awakened our son because it was "bright as day". Now, after 3 months of dimmer spins so so that we bought another on Amazon. If one regulates the light down (twilight state) no longer holds the dimmer the power and the light is bright -> dark -> bright -> dark. Absolutely Nerve-racking when one is at 2:00 clock in the bed and wants to soothe the baby. And he does growl like a 3000W transformer ....
I would all need a dimmer for Babyzimmer recommend this:
Chilitec Delphi dimmer to 300 W, including frame, UP, white, 19721
He has a key switch (I would not use at night), simply turn the voltage down completely and when you go purely easily turn on.
