Holophane, a division of Acuity Brands, is a manufacturers of lighting-related products founded in 1898 in London, England. The company is a UK based (Milton Keynes, England) and US manufacturer (based in Newark, Ohio) of lighting fixtures for commercial, industrial, outdoor, and emergency applications. The company is noted for their 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 licenced and copied throughout the lighting industry. The trademarked name for their borosilicate glass is Endural.

In October 2008, Acuity Brands announced that they were closing the Utica, Ohio and Newark, Ohio assembly operations and relocating them to Mexico and Crawfordsville, Indiana.
