The “Penta” lamp by Robert Sonneman features a clean, architectural silhouette with two chrome supports and a thick glass light panel. Its refined, industrial look makes it a striking and functional desk piece. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
