This applies to all lamps, mine and others, hence a general posting. I feel a need to raise awareness of this issue.
If something is put under stress it will fail.
The picture below shows how this comes about in a lamps fitting and the point of failure. If the cable is flexible rubber sheathed it will be the internal wires that will fail through metal fatigue, if the cable is the harder PVC failure will occur by the splitting of the outer sheath.
I changed my lamps to the type of gland which provides cable support a while ago for this reason.
