Heng Balance Lamp DKNG this brainteaser has stumped millionsThe Heng Balance Lamp is a minimalist light fixture that adds a magical ambiance to any space. When you lift the lower ball attached to a cord, it attracts to the top one (thanks to the embedded magnets inside) creating a connection that switches on the lamps LED light. Separating the balls shuts off the light. The attractive curved design creates the illusion of light passing through the structure. Designed by Li Zanwen. Winner of the Red Dot Design
