Axel Schmid about the original design in 2009: "The table lamp Jetzt uses the world’s first high voltage LED, so there’s no need for a transformer. To be able to run these without housing, the LEDs are cast into transparent plastic. This light block is glued to an anodized aluminum structure, that also guarantees a sufficient cooling effect. The structure is lasered out of a rectangular sheet of aluminium, so there’s no waste in material. Three bending operations define the shape."
Due to the development of LED technology, the new version uses low-voltage LEDs.
