Is the metal back of a GU10 bulb holder live?

[baker332]

Hi all,

I have a dilema, I have fitted some in the wall lights but they need smaller bulb holders, as small as possible - if you have other reccommendations please let me know.

I'm looking at using GU10 mini bulbs and GU10 bulb holders, however these will be pushed into the wall therefore I wouldn't want live metal touching anything. The GU10 bulb holders the smallest example which is what I require expose metal backs like the following:

Is that metal back live? Is it safe to place into a wall.

The bulbs sit into a small cut out:

Bulb properly sat into the wall mount not mounted:

This is my situation at the moment, the bulb is visible and needs to sit lower, there are ways drilling behind which is proving difficult:

Any ideas please let me know thanks

Apologies I don't know the answer to your question. Just wondering about those wall lights. I can't tell from photo, but is it some kind of plaster, plastic, etc shell that is fixed into hole in wall then skimmed with plaster to make it look like part of wall?

Just curious because I've never seen anything like them, but they look very interesting.

Yeah exactly it's solid almost like ceramic, search up plaster in wall lights.

What size bulb holdes do you currently have in there?

Is that metal back live?

I didn't see a metal back - it appears to be a type of insulating fibre board.
But with any off-brand from Amazon, you pay your money, and take your chances!

I'm afraid, I think you may have to drill deeper.

Except for a pendent, an earth wire needs terminating at the fitting, even if the fitting is class II. At least with low voltage (230 volts) only extra low voltage (SELV) can be used without an earth. Even back in 1966 when the earth rules changed, only filament lamps could be used without an earth.

Be it G9 or GU10 fitting, somewhere it needs an earth connection. Often only a parking terminal, but the earth needs terminating. I did google as you said, but it does not show how connected yes seen the

but still needs a parking terminal for the earth to be used in the UK.

Yeah thought as much, just tricky to drill that's all!

They are GU10 bulb holders but they have a larger backing like the following:

Spare Lampholder

These have the black plastic surround, adds more height to the bulb.

Another one with the metal backing:

Thanks for this advice, much appreciated - I've run 3 core, and terminated the earth into a wago at the device and the earth terminated onto the earth pole within the switch.

Good idea on G9 bulbs these require a transformer right, something I won't have room for unfortunately.

These are just GU10 bulb holders essentially regardless of the light itself.

Another one with the metal backing

Again, it's an insulating fibre board - not metal, and not live!

That's great thanks for confirming!
