These lights are often attributed to Gepo, Anvia or Herda, 3 light producers from the Netherlands. However, these lamps were never made or sold by these companies.
In the UK these Prova lamps were also sold by BHS (British Home Stores). There is no label present on this one. Below is the label from the company, it was glued on another, similar lamp.
No information to be found about the Prova company. It must be long gone and forgotten. Prova is also a small town in the north of Italy, some 120 km / 75 miles from Venice. Prova is the Italian word for proof or test.
The switch is made by the Italian company Acciarri. A small company that is long gone. However Acciarri also produced lamps. Sometimes you find one for sale on the internet. Most of the time it is an industrial architect desk lamp from the 1970s. Something completely different than these lamps.
Acciarri produced switches for companies such as Reggiani (Rome & Milan, Italy). Acciarri is an Italian family name, mostly found on the east coast of the country. No information to be found about this company.
The socket and wire were produced by VLM Components, also from Italy. VLM Components was founded in 1945 in Buccinasco, a small village near Milan, Italy. VLM is part of the Relco Group, founded in 1967. Today they are the owners of the brands Relco, Leuci, Relco Lighting, VLM and Segno. The company is famous for the switches they produced that were designed by Achille Castiglioni.
