Stacking is a collection of lamps designed by Rockwell Group in 2007 and produced by the prestigious brand Leucos. This collection is available in different models. Stacking is made in Murano handblown glass.Stacking was designed by Rockwell Group in 2007 using the idea of modular, individually handblown glass cylinders in distinct combinations of colors and sizes. These glass modules are made with a traditional Murano handblown glass technique called incamiciato (Italian for “jacketed” or “layered”), which requires multiple layers of glass during the blowing process. This tedious handmade technique pays off brilliantly as it builds up different colors and opacities in each module. When these modules are combined (you can stack or restack the modules in any combination you desire) they build and overlap colors and opacities, creating sophisticated atmospheric lighting. The Stacking Collection is comprised of three sets of floor lamps (Stacking B, Stacking C and Stacking D) that each have their own distinct personality. Handblown modules in small batches are created by a Maestro in the Veneto region of Italy.Light source:4x GU10 7W Retrofit LED Bulb - (not included) - IP20 - 220V - Dimmer on cord
