Philips SGS201 35w SOX lanterns at night

Photos taken just last night, of a very rare working pair of these. Cambridge used to be home to hundreds if not thousands of these, then they were swept away by the replacement programme 8 or so years ago. From that point onwards, the only ones that survived were a few on private housing estates and city council owned property. Now, only a few actually work, as most either have since been further replaced, have EOL lamps in or have LED retrofit lamps in.
