Lighting Products and Fixtures Design Donut Lamp by Bruce Tao Donut Light is a unique household luminary that there is no obvious switch. It has a simplified form and is flexible for adjust brightness. Its switch is integrated into the bulb. Users simply need to put their hand on the donut and push it gently to switch the lamp on and off. At the same time, the brightness is also increased and decreased through this way. The materials in lamp bulb outer layer are linen which build warm and romantic atmosphere.
