Earth rod for floodlight spike?

[captaincaveman]

Sorry in advance. Didn't sleep well last night and my brain has haemorrhaged!

Just designing power to a shed with 3 floodlights on the lawn from it (swa underground) and I was going to use some metallic spikes to bolt the lights onto but I'm thinking now that would mean an earth rod having to be used at the shed ccu as the supply is pme and I'd be introducing extraneous conductive parts.
I'm right aren't I? or have I overthought this?

Love, Cavey

Nah, you've over/under thought it. The spikes are not stuck in the ground in the shed, so aren't introducing an external potential into the shed. They're not extraneous.

Insomnia sucks mate.

I think the ones I was looking at are class 1 mattg. I was going to affix galvanised conduit boxes to the metal bracket from the armoured cable (and thus earthing the bracket). Just, it occured to me in the event of a broken neutral the bracket would then become live. sod it. I'm gonna have a nap and come back to it lol
