    If the lighting "head" is Class I - there's likely to be an automatic bond to the column itself ... although technically that's not necessarily needed if everything inside is enclosed/sheathed.

    Small c.p.c.s connected to outdoor metalwork stuck in the ground can raise an interesting potential problem with PME diverted N currents ... if the resistance of the column to Earth happens to be particularly low. Class II heads and everything sheathed/enclosed inside the column can seem attractive in such cases.
