  Holophane "Wide Spread"
No. 882 110v Street Light
with Dual Prismatic Refractor

This particular fixture is the 110 volt equivalent to Holophane's high voltage series 862 street lamp. The high voltage lamp had a wet process porcelain body. The 110 volt lamp had a heavy one-piece cast iron crown, body and reflector. The head was so heavy as to require a 1½-inch bracket arm and fitter. (Most lamps used 1¼-inch bracket arms and fitters.)

These luminires may have been available with Jones sockets for 6.6 amp series operation, however this fixture came with a mogul base socket. It would have been used on multiple lamp circuits or with a remote 6.6 amp autotransformer that could be located in the base of a decorative mast.

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.
