Lasts up to 25 years, as if...

I've heard electromigration is a useful phenomenon to exploit if you want things to fail without doing anything to cause it.

Used to generate great profit for the Mastercare/Dixon's/Curry's partnerships in the 80s & 90s (allegedly) as anyone who bought any of their own-brand rubbish like Logik, Matsui etc. will testify. They barely lasted their initial guarantee period. A model followed by so many companies since . . .

Inadequate heatsinks in power supplies seem to be popular; allow the voltage regulator to gently simmer for 18-24 months, then *pop*.

Certainly did. LAP stuff used to be fairly decent at one time but it’s obviously made down to a price now.

I replaced all the bulbs in my house with LAP bulbs from Screwfix. That was at the end of 2017 shortly after moving in. I haven't had to replace a bulb since.

I'm going to need to read that later - thanks
