Please can anyone help me? In my hall, I have a 3 bulb light fitting (halogen bulbs). A bulb went, so I replaced it. So far, so good. Until the other bulbs started going a bit dim, until they completely went out. I took the new bulb out and realised I'd bought a 50w bulb, not a 20w bulb (which I now know to be quite dangerous!). Thought the problem would be solved if I bought 3 new 20w bulbs but all that happens when you switch on the light is they come on very briefly and very dimly, then fade out to nothing immediately. It was quite difficult to fit the bulbs into the springy holder thing, so not sure if the problem lies there too (ie. is there contact being made?) Or have I just knackered my light fitting by putting the wrong bulb in? Any ideas/advice? Thank you - it would be much appreciated!
