Here's an intuitive little light with a unique way of switching on and off. The On/Off Light rests on a table at an angle; its base has an edge that divides two positions of balance. By pushing the lamp over to the other position, it shuts itself off. Seems good for those that like to turn off their appliances with a lackadaisical slap of the hand rather than the nuance and patience it takes to operate a switch. The light is made of soft thermoplastic, which means it won't break if you get overzealous and slap it right off your nightstand. It's available in light pink or light blue and is on clearance now from Y Lighting for $45.
