Holophane is a manufacturer of lighting-related products founded in 1898 in London, England. The hallmark of Holophane luminaires, or lighting fixtures, is the borosilicate glass reflector/refractor. The glass prisms provide a combination of uplight and downlight to illuminate any environment evenly without creating dark spots or glare. This ribbed glass shade/reflector, called “Holophane” is iconic in vintage lighting.
