Lou the Owl is a voice activated nightlight that will help soothe and comfort your little one. The voice activated sound sensor will switch on the owl if your child wakes up in the night. You can then set the timer to automatically switch off once your child has dropped back off to sleep. Lou is comprised of 2 lights as the Owl and Outer Ring are two separate lights. You can use these together for a brighter light or separately for a low glow. They are also adjustable, so you can choose bright, soft or ambient light. Operates on 220V (USB included) and/or batteries (3 x AA, not included).
