If a power outage occurs a few times during a cycle it will not cause a dramatic difference. TIP: In your Mother room you never want the lights out for too long. Buy an LED light with an emergency battery backup. Place it high up in the Mother room. If the power goes out the emergency units sense the power interruption and will turn the light on until the power is restored. Some of these emergency power light backups can run for up to 2 days (or until the battery dies). The great thing is that the power is usually not off more than a few hours. Once the power is on the emergency light units will automatically recharge the battery in the unit.
