The Heavy family, manufactured in the United Kingdom, in addition to its well-known hanging and desktop version, has a wall mount (which can vary in finish and color) and the standard size, similar to that of the Heavy Small. His concept, identical also to that of the others in his family, demonstrates a different approach where a material of daily use in construction - concrete - is used in an unconventional context, as in the design of these lamps that challenge their daily use in the residential or commercial areas. A masterpiece of Decode that combines an innovative idea, with a simple visual aesthetic and the juxtaposition of unusual material for this type of light sources. It has been manufactured in different finishes of gray, bone white and a terracotta finish; Each concrete screen is created individually, with the concrete cast in a mold that is left to dry for several days. During this process, random air pockets and veins are developed inside, so they are never the same, giving a rustic, unique and irregular touch that contrasts with the smooth exterior of the screen. They can have different colors in cable, connector and canopy.
