Design team Yet! Unknown pays tribute to the ingenious creation of Wilhelm Wagenfeld lamp, the WG 24 with their own modern twist called the WT 12. This concrete lamp radiates an ambiance of softness and light despite its cold and heavy appearance. It uses a 6W LED module to maintain a long life as well as being energy efficient. Unlike Wagenfeld’s original design, the WT 12 emits light towards the ground instead of in different directions.
