Profile view of luminaire.

Holophane name and 1930s vintage trademark.
|
These lamps used Holophane's dual prismatic refractors that were produced to provide various illumination patterns depending on how the glass ribs were formed. This particular refractor is omnidirectional.
These lamps would have been used for street lighting on smaller "multiple" circuits or using 110 volt taps from high voltage series circuits. They were also practical for lighting parking, industrial and railroad lots. Here are photos of the lamp disassembled. |
Here are images of the lamp returned to outdoor service.
