This is weird. In my sitting-room there are 8 ceiling lights - the flush fitted halogen sorts. Each bulb is 50w. I installed a dimmer just before christmas, and everything was fine. Then one of the bulbs blew. After that the dimmer wouldnt dim, the lights were either full on or off. I thought it must have been a dodgy dimmer so replaced it. That was last week. Last night another bulb blew, and the same thing happened - the dimmer wont dim.
Can anyone think why this keeps happening. The dimmer is suitably rated to handle this number of bulbs.
