GE "Double Ring" Domed Radial Wave

Restored "double ring" style GE domed radial wave. This light is special to me because this type GE was used on the street when I was just a tot - probably the first kind of street light I ever saw. The double ring provided greater insulation for high voltage series circuits that were regulated at voltages higher than 2kv to power for longer strings of lights (thus requiring higher potential-to-ground circuits.)
