Ok, I'll have to read that item later due to shortage of time right
now, but I'm harking back over 40 years to the first generation of
LEDs

I saw my first ones in 1969 - that's over 50 years ago.

"over 40 years" covers 50 years ago.

true but 'over 50' is more accurate - gives an even longer time ago,

Yeah, I can see how it could have been taken to mean two different
things on reflection.
