I was looking for a night to reassure my daughter when she wakes up at night and this is perfect: it plugs into industry and we thus prevents the batteries, the light is soft and perfect, neither too strong nor too weak, for my daughter's room (20 m2) where it is placed next to the door to the opposite bed It has the advantage to go out on her own as soon as you open the shutters or you turn on the light. So good I ordered green for my son.
