Which would you expect to be more resilient to shock, a rough service
filament light bulb or a LED bulb (both B22)?

The LED lamp by a long margin.

LED by a very long way

Perhaps this wouldn't be a good choice though. ;-)

I nearly bought the candle version of those, but they did not have the
light output I wanted. (Not for my inspection lamp.) Are they any good?

IME they are excellent - I much prefer them to the "normal" format of
LED lamp, since their light output is pretty much as omnidirectional
like a normal filament lamp. So they work very well in cap down
orientation, or when fully enclosed in the type of shade or luminaire
that benefits from all round light distribution.

The light quality also does not (to my eyes anyway) have that slightly
odd greeny/yellow quality that you get with some LEDs - they are the
closest thing I have seen to a filament lamp so far.

(I have a mixture of the 40W and 60W equivalent ones).

BTW, order them from trade.ledhut.co.uk if you can, and they are cheaper
than from the retail site.

LED.
However that is not to say that some constructions are better than others
of both types of light.

I'd assumed all LEDs had a pretty robust anode and cathode. Unlike the
filament in a incandescent lamp.

You might be assuming incorrectly. I've no idea how robust these "pseudo
filament" bulbs are but they're bound to be more fragile that a pcb mounted
led.

Could well be. But then I've no interest in them. The question was about
rough service against LED, so I assumed something like an inspection lamp.

If "rough service" is your thing, I'm sure that there are whores' parlours
that can accommodate you. ;-)

Not those LEDs that look like incandescent filaments.

It all depends on how the additional components in the LED bulb are
mounted. Most of the support components for LED bulbs are just mounted
on a small circuit board loosely fitted in the base of the bulb. They
may be the point of failure when subjected to shock.

Out of curiosity I have dissected my first LED lamp failure and was
slightly surprised to find that the long (52) LED chain is still perfect
but the power supply has failed. I checked all the diodes manually and
in series. So it looks like LED lamps fail the same way as CFLs but a
bit more slowly since they generate somewhat less heat.

I suspect it will be a cooked dried out PSU capacitor. That require a
second level of careful cutting into the body to investigate.
