Holophane is one of the oldest manufacturers of lighting-related products in the world; founded in 1898 in London, England. They are a UK (based in Milton Keynes, England) and US manufacturer (based in Newark, Ohio) of lighting fixtures for commercial, industrial, outdoor, and emergency applications. The hallmark of their products is a glass reflector/refractor. In addition, they manufacture lenses for street lights, including General Electric, Cooper Lighting, and Lithonia Lighting. Holophane has been integral in the Illuminating Engineering Society of North America since its inception in 1906, with the first meeting being held in their headquarters. 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" or "Holophane style/type" is iconic in "vintage" style lighting, and is licensed and copied throughout the lighting industry. The trademarked name for their borosilicate glass is Endural. Holophane is a part of Acuity Brands. - Area Notes
