LED light fixtures are really catching on, which is great, since they are significantly energy efficient than fluorescent and incandescent lamps. And while the initial costs are higher than traditional lights, one does recover the cost over a short period of time.
The LED Hourglass Lamp Collection by Danielle Trofe further ups the environmental ante, as the lamps are illuminated using the kinetic energy of falling sand. The lamp hence fittingly shaped like an hour glass and we love the modern design of it.
The LED Hourglass Lamp Collection was first spotted at the NY Design Week 2012 and it needs to flipped continuously to work and while this maybe cumbersome, it does spread awareness of the limited energy sources on Earth.
