It's not a GU10 bulb, or other one that runs off 12V DC. It really is a 240V
bulb, like these ones:

And Stu - I thought our mains supply *was* 230V these days? The continent
upped from 220 to 230, we dropped from 240 to 230, to harmonise.

Ben: that was my supposition. But then, electronic circuits always seems to
do the exact opposite of what you expect them to.

I'll try my remaining bulb of the two-pack, but this time I won't touch the
glass, and will solder connections properly (rather than just wrapping
wires) to see what happens...

Thanks for all your suggestions.
