The idea for the lamp's shape came when the designer was restoring an old 1960's radio at home. While searching for spare parts for the radio, he was captivated by the glow that emits from the tube amplifier. The simple oval shape and the glow of the lamp is an obvious reference to this, just as the name Amp refers to the English term; tube amplifier. The proportions for each lamp have been carefully designed to ensure just the right balance between hard & soft and transparent & opaque.

Simon Legald says: "One can't always define where an idea for a new product comes from. But this time the inspiration was drawn directly from radio and hi-fi equipment. This is clear in the design of Amp. There is something special about the round, transparent shape of a tube amplifier that I thought would translate nicely into a lamp. I opted for the same type of glass used for an hourglass, as the shape had to be curved and narrowed in. To counterbalance the delicacy of the glass, I used marble. I think that the two materials work well together.
