I moved into a house with an obscene number of GU10 LED downlighters. The bulbs were all mid market (I think) brands like Energizer etc. I’d guess they’re coming up to 7-8 years old and I have now had to replace most of them, probably 30-40 bulbs from a couple of manufacturers that all just started to fail over about 12 months.

I also have quite a few Philips Hue bulbs, I’ve had 1 fail out of 20-30 and I think that was not the LED itself but some control board. Some are going on 10 years old.
