Put lamp in holder and the power dies... WHY?

[Ladders]

Hi all. So called out to a domestic properety as light fell off ceiling. Put it back together and power all shows good. L/E, L/N power 230v no reading N/E. But no power when connected to fitting? So swapped fitting for 6" pendant and did same? So took the lamp out of pendant and power readings back to normal? Any offers on what is going on? It looks like the lamp is acting as some kind of switch and cutting the power but who knows with out further investigation...

People take the mickey out of me for using one of these but it will only give a full light when 230V present. You can soon trace bad connections. Test-meter.co.uk sell them

I have one of these.

Excellent bit of kit, but rather expensive for what it is.
