The Good Night Lamp comes as a Set of a Big Lamp and 1 Little Lamp. You can add Little Lamps as you go. Each Little Lamp represents another loved one or friend.

We've chosen to connect the lamps with wi-fi technology. When you receive your Big Lamp you use a USB cable to connect it to your laptop and program it to remember your wifi name and password. Once that's done, you can plug in your Big Lamp anywhere you like. The Little Lamps connect to a Power House which also has a wifi chip which you program in the same way. When you collect many Little Lamps, simply connect them to each other.
