To "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. An hour-glass like mechanism is turned over and the weights are placed in the mass sled near the top of the lamp. The sled begins its gently glide back down and, within a few seconds, the LEDs come on and light the lamp,
That is very cool.
The LED lightbulb should last a lifetime so you are looking at a family heirloom. Kind of a 21st century candle.
