This is an original 1960s Paris Globe Holophane streetlight from Paris, France, now converted to a pendant light. The hallmark of Holophane luminaries, or lighting fixtures, is the borosilicate glass reflector / refactor. The glass prisms (ribs) provide a combination of up light and down light to illuminate any environment evenly without creating dark spots or glare. Therefore, this light is perfect for any application where even lighting is desired. The Holophane glass was cast in two halves and joined together. the technology was pioneered in the United States but became the standard lamppost design throughout the Paris region (especially in parks) in the 1950' and 60's. This lamp has been acid-bathed to remove accumulated dirt. The lamp has been converted for US use and comes with a chain.
