comments
  Instead of the usual mercury sealed construction, this Lane-Fox lamp employs platinum lead-in wires through a glass pinch. These platinum lead-in wires rise to larger diameter copper posts which are crimped over the platinum lead-in wires. As in the mercury seal constructed lamps, large drilled carbon cylinders are used here as joint to fasten the carbonized vegetable filament to the copper posts. Indian ink is used on the top of the carbon cylinders as a paste joint to secure the filament to the carbon cylinders. This simple construction seems less common than the more complicated mercury sealed construction so often associated with Lane-Fox incandescent lamps.
