Our little light collection just welcomed this oh so sweet moon to the family. This soft yellow moon looks great in any nursery. Our whole little light family is battery powered with a clever timer function. Let your little one fall asleep comfortably in bunny’s soft glow and the light will turn off automatically after 15 minutes. You can choose to put the light on, off or on a timer. When you switch the timer on, the light turns off automatically after 15 minutes. This saves battery power and is better for the environment! We advise you to use this timer, because the included batteries last for about 20 hours.
