Gravia lamp provides silent, eco-friendly light using the force of gravity. Well, almost.
Clay Moulton wanted an eco-friendly solution to home lighting, so he designed the Gravia LED lamp. Aside from just relying on the LEDs to reduce power consumption, Moulton also decreed that the lamp would be powered by the force of gravity.
In basic terms, it makes use of a slow-falling mass to turn a rotor. This powers the 10 high-output LEDs which are diffused by an acrylic lens. Silent, cord free, soft lighting with an output equivalent to about 40 watts, just by moving some weights from the bottom of the elegant casing to the top.
Not only that, but as the acrylic lens deteriorates and yellows, it will give an even more natural hue to the blueish, otherworldly glow you get from LEDs. The catch? It doesn't actually work yet. With current LEDs it would take something like two tonnes of weights to generate enough power, but Moulton is convinced that with the speed of lighting innovation it's still a viable candidate for production one day.
