If I was pushed on a year (without knowing otherwise) for the Fontana Arte Huna Suspension Lamp, I would have guessed at 1930s. But it actually dates back to 1965.
From Archivio Storico, the light certainly has that 1930s utilitarian feel, albeit with a lot more class than the kind of thing you might have found in a factory or warehouse. In terms of construction, the Huna offers a painted aluminium pendant with black or white interior, complete with a staineless steel suspension cable and transparent power cable.
If you want one in your home, it sells for £174.
