Marketed as 240v, no earth terminal, can't see any double ins symbol..

my sparky is off on holiday, and has left me doing the donkey/**** work of wiring all the slave down lighters (the simple bits, loop in, loop out) so he has less to do. I then leave it hanging out e ceiling, he checks yada yada..

So I've come to fitting these things:

And there isn't an earth connector, just a two terminal jb. Im fine with wiring a 3terminal/chocbox/wago etc but the double insulated bit still nags at me- from the pictured construction does it look like it is DI?

Not really possible to tell.

If the connector and lamp holder are such that a live wire cannot contact a metal part then they may be class II (DI) but they should say so - nothing in the instructions?
I would say that if they don't state it then they are not.
Normally the bracket holding the connector slides into the spring so if that became live it could make the body live.

As they do not supply a lamp (bulb) for it then some may fit 12V; I'm not suggesting you should.


It does state the 'shade material' is metal - is it?

Thinking about the construction, the shade may be electrically disconnected from the rest of the bezel; the bulb clips into the shade, the shade to the bezel and it's the bezel that holds the connector jb etc. It's hard to see how it'd become live without a significant physical failure..

That sounds remarkably untrue.

And yet, that's the way it is. Fancy that - the truth really is stranger than fiction!

Not wishing to be adversarial etc, but this is a DIY site so if it irritates you that someone is doing something themselves perhaps you should be posting over at The IET?

Seeing as quartz halogen lamps are about to be banned I wouldn't bother fitting those anyway.

Because GU10 LEDs haven't existed for years and aren't about to be banned, are they?

I would expect the lamps at Class II, but I had the same problem, my mothers kitchen was re-wired all, but the lights, the lights 1954 were not earthed, that was normal back then, it was 10 years latter that lights had to be earthed, so I wanted a class II fitting, I bought a class II fitting from a web site specialising in class II lights, however there was nothing about the class II lamp which was different from a lamp at half the price from B&Q, except for the sticker.

However to get the guys doing the kitchen to fit the lamp, I had to pay the premium and get one with the double square sticker.

So buy the lamp from an electrical whole sale outlet with the sticker if you want some one to issue paperwork, if you don't care then use Tesco.
