I have two contemporary wall 'uplighters' on my lounge wall. They are fed from the ringmain via a switched fused spur and a dimmer switch. The lights each use a GU10 50w spot bulb.
We tend to leave the dimmer switch on about a 3/4 setting and just switch the lights on and off via the switched spur.
Yesterday, when the lights were switched on, there was a brief flash of light and both uplighters went off.
The fuse in the spur had blown and, on replacing it, I found that one of the GU10s had failed. I replaced it and both lights are now working again - but the dimmer isn't...
The dimmer is a rotating knob of course. Turning it clockwise first switches the lights on - but at the lowest dimming level. Further clockwise rotation raises the brightness of the lights. There is now no dimming effect at all, however. Turning the knob clockwise just switches the lights on at their brightest level and further rotation has no effect at all.
So, after that lengthy description, is the dimmmer switch completely stuffed?
