Is it a bell? Or a helmet on a stick? It’s neither – this is the Verner Panton Pantop lamp.
Dating back to 1982, the Pantop is indeed bell-shaped, which should mean a good diffusing of light. The shade is available with either a white or brushed aluminium shade, both standing on a chrome stem and base.
It retails for £99. If you like the look of it, but don’t need a new table lamp, there’s also a version for your ceiling available for the same price.
