Needing to replace some lights in the kitchen, I got some arrays of 4

Neeldess to say several flickered and after about 100 hours two bulbs died.

I had bought 20 odd dimmable GU10s online and tried to replace them. One
I managed, but the other simply will not tiurnm to click in place.

Anyone got any ideas what this cheap chinese **** is up to?

I got mine (all GU10) in B&Q their dial/dail range dimmable warm white they work OK in a dimmer designed to dim LED lights, although some on her claim any dimemr can dim LEDs.
Think they have been in use for about 1 year now no problems, I have 2 LEDs and 4 halogen in the 6 way light. In a bedroom I have 3 cool white dimmable LEDs on a LED dimmer for the last 2 years no problems.
I have a 4 way soptlight thing in the kitchen with 4 dimmable LEDs with a LED dimmer again no problems in 2-3 years, but these weren't DAIL and they wouldn;t fit in the front room 6 way lights they were about 2mm too short, the pins never properly engaged the sockets, because the bulbs had 'wings' or rather fins that stopped the bulb from being able to sit properly in the holders.
