>>LED bulbs usually fail when the circuitry cooks - the LEDs themselves should last decades

I was dumping a box full of "free bulbs " at the tip recently.
As they were the florescent type I of course went to the appropriate cabinet that had mostly
the familiar long tubes in but also an awful lot of LEDs.
So much for long life :-(

>>Crap bulbs in short.
I have had several fail in the last few weeks.
60W clear candle BC which IIRC and not supposed to be on sale?
The fitting was cap up. The failure was a bang that tripped the RCD and SWMBO was not amused.
I found the glass envelope, intact on the floor and the cap still in situ.
The last time it happened I fitted a branded Halogen version that I had in stock and that lasted a week.
New years resolution.
Bin all the cheap bulbs - I am off to get some LEDs :-)
I do hope they last.
