Yup this is a very inefficient way of reaching a target illuminance.

Multiple sources spread over an area would be more efficient, as each LED could run at lower current and temperature, which increases their efficacy.

The light would also not have to bounce off ceilings/walls multiple times, while some are nice for diffusion, every reflection is lossy.

I suspect you’d also get better reliability.

That would certainly make certification easier, but as I suspect you understand, wouldnt achieve it alone.

Even if every component was CE qualified, the combination would have to pass its own testing, plus there are a lot more to the standards than just not electrocuting you immediately upon contact.

I can't see any of the energy efficiency labelling that would be required in the UK or EU for example...

The live prongs are insulated to such a length you should not be able to touch any conductive part before the plug is no longer making electrical contact with the socket.

It's likely you got a small zap from a filtering capacitor inside the device that had not yet discharged.
