Holophane is one of the oldest manufacturers of lighting-related
products in the world; founded in 1898 in London, England. They
are a UK and US manufacturer of lighting fixtures for commercial,

their products is a glass reflector/refractor.
The hallmark of Holophane luminaires, or lighting fixtures, is the
borisilicate 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.
