The table lamp Cuboluce by Cini & Nils emits a concentrated light beam that can be directed when using the lid/reflector. Forget fumbling for the light switch: when you open the lid, the light goes on; when you close it, it goes off. That is why the lamp may be used to read in bed. Cuboluce is made up of technopolimers and is available in many colours.
The lamp is part of the permanent collection at the New York Museum of Modern Art.
