Gepo N.V. was a family business founded in 1965 by the brothers Posthuma: Peter(sales director) , Jules (purchase and marketing), Archi and Rob (production). The name Gepo is derived from the Gebroeders (brothers) Posthuma.
The brothers started their business with +- 35 euro/dollar borrowed from their mother. In 1972 the company had a turnover of +- 1 million euro/dollar. It was always the intention of the company to produce affordable lamps for the middle class. The Posthuma brothers not only wanted to democratize the light business, but they also wanted to provide every lamp with a dimmer. At that time dimmers were made with a resistor; they were expensive and often broke down. The plan has never been successful. Gepo ended business somewhere in the early 1980’s.
The electric parts are made by the Italian VLM Components company. All electric parts were produced in the mid 1960s, so presumably also this table lamp.
This lamp was acquired when Veduco, once a famous design shop in Antwerp, Belgium, ended business in 1996. The shop was located in the Carnotstraat near the central station. In the 1960s, 1970s and 1980s a boulevard famous for all the furniture and design shops.
This lamp, together with an orange one, were the last 2 lamps to be found somewhere in the basement before closing the shop.
