SW4 is a small, more compact version of Blown, the pendant light with a unique textured surface created by London-based design star Samuel Wilkinson. In a choice of silver lustre or opal glass, he arrived at the exact form for the mouth-blown glass bubble by applying 3D software to chart the refraction of light within. Danish brand &Tradition's head Martin Kornbek Hansen says Blown "not only illuminates a room, it also transforms surroundings into art" with its patterned effects—more subtly glowing in the opal version or more enthrallingly intricate in the silvered. "Whether you choose to have one lamp or several together as a cluster, the effect is amazing both on and off," he adds.
