Re: The lightbulb conspiracy
Must admit Dave I have never heard the term 'Supercoil' but I'm surprised it was not taken up by a leading lamp maker. The 15 and 25w lamps were always single coil, often a long filament strung between spider supports.
They were delicate. The best ones were manufactured for the hood lamp on the Hoover vacuum cleaners. They were very rough service! J.
