plasma night light bulb
This is embarrassing to say but when I was younger I was afraid of the dark. I’m sure this is common amoung young kids. For some reason I couldn’t sleep in the pitch black. Then I learned to open the blinds and your eyes will adjust with light coming in. Or you can get this plasma night light. It works with your 110volt standard power outlet. It will last for years. The bulb puts only a little bit of heat out so no worries with the children or burning up your curtains. It retails for $9.99 from think geek.
