Why do led bulbs flicker?

Dear experts, I have read about other people's similar problems and your answers; however I have a specific problem, namely, when I install gu10 220v led bulbs they all work properly and after some time, let's say 15 days or so, some of them start to flicker, and usually only one out for four, for example. Why is that? Many thanks

Poor quality LED lamps. A decent LED lamp costs £20 - £30, a lot of the ones that are under £10 are normally poor quality and suffer from the problem you describe.
