The Prism Nightlight is based on a playground game that many of us played as kids. Whether or not you partook in the joy of seesawing, most people know how it works. When weight is put on one side, the other side is raised and vice-versa. The Prism Nightlight uses that same technique for its on and off switch.
By all accounts, this nightlight doesn't look like anything special. Luckily, the Prism Nightlight doesn't go by looks. The actual light part of it is large, so it will provide a good amount of ambient light for a room without being overpowering. It's also easy to use because all it takes is a tip one way or the other to turn it on and off.
