*****USUALLY SHIPS IN 2-4 WEEKS***** Design Neil Poulton,2017Made in Italy by ArtemideCalipso’s unique honeycomb surface was generated by feeding a photo of the moon into an image-based algorithm. The resulting fractal shape has an impure geometry that displays the irregular beauty of nature. The diffuser is built from an organic honeycomb-like shape with tubes of varying diameters, seemingly arranged in a random geometry. This honeycomb characterizes the lamp both aesthetically and optically - not only is it visually pleasing, but it also provides an even and comfortable light emission. The result is a highly emotional lighting object that joins together optical and aesthetic intelligence. A product positioned perfectly half-way between home and professional use, Calipso is suited to a variety of applications. Driver is compatible to both 2-wire dimming and 0-10V dimming options.
