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.
