Having night light in the bedroom helps save energy in a way that it only uses a small watt of electricity. Also, it is not so bright for my eyes whenever I go get some water to drink in the middle of the night.
We also placed a night light in my daughter’s bedroom. It will help conserve energy. In addition, my little girl will not get too much brightness from the lamp on the table. We make sure that she feels safe and secure before we turn the night light on.
