At first glance, you might be thinking Guzzini, but this is actually a Double Dijkstra Arc lamp.
This eye-catching 1970s design consists of two chromed metal arcs and two plastic shades, the plastic being double layered with a white interior contrasting with the brown outer shade. There's also an on/off switch and the option to move both shades individually from each other.
Fancy it? The condition is described as 'very good' and the price right now is £28.21.
