Heng Balance Lamp is a series of desk lamps with a twist: where most lamps have a standard switch, Heng Balance Lamp is controlled by two wooden spheres. In balance-- When you lift the lower wooden sphere, it will be attracted by the hanging one and remain suspended in mid-air, switching on the light. Versatile -- It is not a source of light, but also a piece of art. Design-- We adopted a design where the lighting element is embedded into the frame so the light can find its way out. The gentle curve makes it easy to the eye and calming. Materials-- The outside frame of the lamp is made of ABS plastic, Regular size come in 3 color options, black, white, and red; Mini size we chose Dark Grey as its standard color, which works great with warm, calming light. Red Dot Award Winner-- Heng balance lamp. An interactive way to bright up your room.
