Kuplat in Finnish means bubbles. Kuplat is a pure design classic by Yki Nummi. The lamp consists of two acrylic shades of different colours, one nesting inside the other. The white acrylic inner shade functions as a reflecting surface for the light. The outer transparent acrylic shade comes in various alternative colours. The two shades are mounted by a conical shaped white cup. The lamp is available in e.g. smoke grey, The inside shade is always white.
