    Gravia LED Lamp; Powered the Force of Gravity

    by Street Glow

    People are always looking for "greener" alternatives and, in my opinion, powering anything by the force of gravity is "green."

    And the Greener Gadgets Conference in New York agrees with me, as they had awarded this gadget a second place. Called the Gravia LED Lamp, it literally does run on the force of gravity by the use of a slowly falling mass that spins a rotor which, in turn, provides power.


    The lamp which is made of acrylic lens and LED lights, was designed by Clay Moulton of Virginia as part of his Master’s thesis. To power the lamp, the owner has to place the weight on top of the 4-feet acrylic column.

    The moment it moves, the LED lights are turned on. Brightness output is 600-800 lumens or equivalent to a 40-watt incandescent light.


    The lamp is expected to have a lifespan of 200 years (if it manages to stay in one piece that long) when used 8 hours per day everyday. You don’t have to worry about it adapting a less-than-attractive look in the future, as it actually improves over time, just like fine wine.

    LED lights emit a harsh-looking bluish light by nature. After 10 to 15 years though, the acrylic becomes yellowish and helps give your lamp, a classy appearance.
