this must be something obvious, but has me baffled
i have three uplights, bulb blew in one, replaced with a known good bulb - and that (and only that) light still doesn't work?
still has mains going to it (tested with a magig glowy pen)- wires look to be in place, no fuses blown/triped (but on same fuse as the other two lights anyhow)
something screwy going on! same thing happened with some fluro lights in my kitchen, which still don't work
ideas please
