Those Maplin 22W lamps have a 2-core mains cable and mine produces a triangle wave of several volts peak to peak on a scope with the probe held an inch from the tube at something like 25Khz.

No wonder your neon tester produces a false signal. If you have got a Megger you can test between the plug pins and the metal work. It should be fine.
