Holophane Originally founded in 1898 the hallmark of Holophane luminaires was the borosilicate glass reflector, which acted as a prism providing a combination of uplight and downlight, to illuminate any environment evenly without creating dark spots or glare. As a result Holophane lights were frequently used in churches, as street-lights and to illuminate older factories and industrial spaces.
