I had an LED bulb go in my kitchen last night. A few years old, but the box it came in says 15 000 hours. I'm thinking 6 hours/day average, so under 2500 hrs/yr, probably didn't make the 15 000 hours.
Anyway, the interesting thing is how it went. Switched on, flash of light, then nothing, just like any other bulb. BUT if I switch it on again it gives me another flash, not at all like a steam powered bulb, and it keeps doing it for many iterations.
I've changed it for a new one now, but do any of you electronics experts know why it would light up and power down instantly? Google says something about "drivers", but in the immortal words of the Queen of Queensland "please explain?"

so it's obviously not the LED, these things are low voltage DC, your supply is much higher voltage AC. The "drivers" are the interface. sounds, like there is a safety override in there that cuts supply.

Most LED bulbs are overdriven, they esentially over currents the LEDS, in an attempt to make extra margins. $$$

Yours sounds like a capacitor has dried up and is failing but that is just a guess.

There is a Youtuber that does hundreds of videos about LEDs call Big Clive, turns out the best quality LED globes go to Suadi, the goverment there mandates a certain level on quility for globes?

So the "driver" is a tiny circuit board? And somebody with sufficient determination could replace it to get the LEDs working together again?

Of course! But you may have some some failing or failed LEDs to replace as well due to them being overdriven.
All repairable but it's cheaper to buy a new one.
Just like the manufacturer planned for you.
