Dannyelle Trofe, the Brookson design studio, brought the idea of ​​two LED Hourglass Lamps. The working principle of these two hourglass lamps is to skillfully convert the kinetic energy of the falling sand into the electric energy needed to illuminate the LED. This design makes the user have to participate in it. After the sand on one side is leaked, the LED must be manually turned over. Achieving a sustainable energy supply that promotes awareness of the limits of energy.
