Strange that the "Cyclops" was so adventurous (avant garde, one might say) yet the P4 developed into the epitome of British traditionalism & conventionality.
The biggest problem we had with the Alfa lights was that the Italians used steel connectors instead of copper or aluminium and they rusted terribly, especially the earths, endless back feeds were a real nightmare.
After too many years (long ago) I realised the Italians build their washing machines the same way, if Indesit and Zanussi are anything to go by. The house now runs on Bosch/Siemens. Lesson learned.
