I didn't expect too much for a tenner but the Wall-mounted L.E.D. Reading Lamps I found in A Certain German-owned supermarket looked ideal for the gloomy corner of the workshop, to illuminate both mill and jig-borer.
I was not prepared for what I found when I unpacked it yesterday to mount it on the shed's Stirling-board lining. Alerted by having been an internal PA Tester for my last employer, I refreshed my memory on the official signs and squiggles.

The lamp's label and manual bear the " CE " mark, the concentric-square symbol meaning " Double Insulated ", and " IP 2 " rating.
The CE doesn't mean much; but the squares are the IEC indicator that the item needs no earth as it is inherently insulated against a failure making external part "live".
IP Class 2 shows protection from ingress of dry objects, and the lamp would pass that when installed as intended.

I found –
Two-wire lead (appropriate for double-insulated equipment) from the wall-mounted switch-box, to a worryingly cheap-looking, transparent plastic 13A plug with a fully-plastic earth-pin. Possibly brittle material.
The switch-box's open back is not a problem as it is for screwing to a wall, but though the switch is behind a partition the whole assembly did not look double-insulated at all.
Switch-box, flexible neck and GU10 lamp shroud: all bare metal. Full continuity by test-meter "beeper" from end to end.
So although rather unlikely, a fault could render the outside of the fitting "live"…
I telephoned the company, agreed I would take the lamp back for a refund, and the office lady said she'd pass my complaint to the customer-services people. I commented that the manual says it was made in Germany, which surprised me as that is one country noted for Processes and Procedures and Standards!
Whether I will be contacted by the company remains to be seen…
