Orange is the colour and Guzzini is certainly the 'look'. But this isn't a Guzzini light, this a Herda wall lamp, which I would guess dates from the early 1970s.
Although it just might have sneaked into the late '60s. Either way you get the point. And with that image, you get the idea that this would fit effortlessly into a space age-style interior.
The lamp has a chromed metal base and metal shade, with the option to move the shade in any direction, should you want to target your light. Helpful if you are reading for example.
The base has a 60cm reach form the wall and the shade is 21cm in diameter. Both shade and base are described as being in 'good condition' with no obvious defects. Right now, it's just one pence at auction. If you like the look, but not the colour, the same seller has a yellow wall light in a similar style. More on that here.
