Set of 2 design ball lamps in chromed metal industrial pendant lights 1970

This lovely pair of vintage adjustable lamps is made of chrome-plated metal. They date from the 1970s in the style of targetti lamps. These industrial ball-shaped pendants are silver-colored and the interior reflector is white enameled. They are equipped with a rigid adjustable stem and a disc to hide the electrical wires. Is there a "gmi" mark. They measure approximately 16 cm in diameter and 70.5 cm in height. I note dents and signs of wear, the chrome is pitted (one of the lamps is more affected than the other). The electrification must be revised.
