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.

In the absence of any evidence to the contrary it certainly seems likely.

Pretty concerning for such a high power device.

Totally agree, I've also done electronic design work in the lighting industry, though not enough to end up on any standards body.

I was trying to ask in as charitable way as possible...

Would you be able to post an image of the labelling/markings on the unit?

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...

I'm really curious how they handled certification of a design that was changing apaprently up to the minute it was delivered...

I'm curious that this story seems to be missing a big part of hardware design - certification.

It seems like the design was being changed up to the minute these were shipped to customers, so it doesn't seem possible that any testing was carried out on the final design?

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.

It's possible that buying the TV and removing the toxisity is more effective - you get the subsidised price, but the manufacturer never makes the ad money back.
