I know of people using former LMS incandescent bulbs.

Seems they were over-engineered, ie bout built-in obsolescence, and consequently do not burn out.

Not sure when, no doubt the relevant gen is to be found online, lightbulb manufacturers decided longevity in their product was not in their best interest, so they engineered it out.

Would be really interesting to hear if anyone can confirm the Jonny Moggy story, I certainly remember much of his stock being pre-war!

I have got red LED indicators on printed circuit boards that have been performing fault free since the 1960's, but I gather the electronics used in driver circuits for LED lighting are the weak link where failures occur. (Though output does slowly reduce)
