There is no mains connection. Do these items need PAT testing?

PAT only applies to mains kit, no mains nothing to test. You may come
across a "safety officer" who thinks anything electrical has to have a
PAT sticker...

Does anyone have experience of dealing with fire officers about such
matters?

Fire risk is another matter though, is there "adequate"
ventilation/cooling of the lamps?
