Had a set of 6 led bulbs fitted in the kitchen some 4 years ago LED GU10 4W 4000K one has just ceased working i had a spare one so i fitted it and 10 minutes later it went off, i am puzzled by this does anybody have a clue whats wrong.thanks
Had a similar problem when I changed from halogen to LED in the bathroom, one bulb kept flickering.
A half dozen in/out twists cured the problem so, yes, maybe a minor fault in the fitting.
Spookily enough I was remarking to the cook this very afternoon that the thousands of hours life claimed for LEDs that we have in the living room seems to be optimistic at best. I've had to replace four since the fittings went up last year.
