Yes, its very common for bulbs to trip a standard MCB.. as they arc on
failure and draw quite large currents before burning out. Mine do it
every time..I s'pose I could replace then with slower acting ones..but I
can't be arsed..

Out of interest, how do they specify slower acting ones ? I've never
seen them, but then for a twice-a-year event (the MCB tripping on bulb
blowing) I also fall into the CBA category ...

Seems like CBA applies to me, too! When the bulb went late last night,
I'd already switched on the bedside light, so I thought, stuff it, I'm
not going to grope my way down to the kitchen now, find the torch,
open the inner garage door, get the stepladder and clamber up to the
consumer unit.

I didn't actually get round to flicking the switch back up until about
9 a.m. this morning.
