Is this voltage there when the bulb that is good is in? I'd suspect not.
Then its just a case of looking backwards to find where it goes away. Rodent
damage perhaps? Loose Connection block somewhere?. If that does turn out to
be the case, check any others to save time later on.

I have a series of 8 mains voltage outside bulkhead type lights. (fixed
under the soffits).

One stopped working so i duly had the cover off and replaced the
lamp. The light did not come on. Tested the lamp in another source and it
works OK, so not that.

I changed the lamp holder and tried again, still not working.

I have tested with my multimeter and get approx 240v at the lampholder, so
not a broken neutral.

All the other 7 lights are working OK.

Any suggestions/solutions to try?
