Holophane

Holophane, a division of Acuity Brands, is a manufacturer 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.

Holophane has been integral in the Illuminating Engineering Society of North America since its inception in 1906, with the first meeting being held in the headquarters.

The glass prisms provide a combination of uplight and downlight to illuminate any environment evenly without creating dark spots or glare.

In October 2008, Acuity Brands announced that it was closing the Utica, Ohio plant and scaling back its Newark, Ohio assembly operations and relocating them to Mexico and Crawfordsville, Indiana.
