I have 11 spotlights in my kitchen which are 12V MR16 fittings. Recently they've started giving me trouble. Only 5 out of the 11 still work correctly, the rest have gone
I decided it must be a heat issue - the halogen bulbs I had get seriously hot and I thought they might be burning out the fittings. I bought 1 new LED bulb and tested it, and it worked perfectly.
I went ahead and ordered another 4 of a slightly different brand. After installing them this morning, they stopped working. They work when I first hit the switch, then about 5 seconds later they cut out. Worse, now the one that worked fine is also doing this
Has anyone any idea what could be going on here? I intend to call an electrician to sort it out but I'm curious if anyone's seen this happen before. It's made me think the 240V - 12V transformers on each fitting may be the issue
