Large Vintage Holophane Lamp
Large glass lamps by the English maker Holophane (stamped on the lip), Circa 1960. They probably hung from a factory or commercial premises ceiling. These have been slightly adapted for domestic use at some point as they would have had a large control box and transformer for a HID lamp. They have a modern E27 screw bulb fitting with approx 2m of 3 core Black braided cable. They'll need a heavy duty chain and ceiling rose they weigh around 7kg each.
Overall good condition, marks consummate with age
