Ever since we moved into our new home there has been a problem with certain lights blowing. At first we thought it might be cheap bulbs so we we got some fancy led bulbs. That didn't solve the problem so it was suggested that it might be the light fittings. I have replaced all of these and the problem still persists. Both fittings use g9 bulbs but on average a bulb blows every couple of days. Works out quite expensive as you can imagine. Does anyone have any ideas what could be causing this? And is it something I might be able to investigate or is it best to shell out for a local sparky?
