That's fine, then - it's that very last bit which is important.Fear not I inspected it carefully and it was very secure the lamp holder end was firmly attached and to the hollow rod, and the cable was held in to rod with a strong and firmly tightened grip.
I have to say that I'm not too impressed/comfortable with designs which involve the weight of substantial light fittings being supported by electrical cables - but, as 333rock333 said, it seems to be a current fashion.
Kind Regards, John
