Brick wall lights - SWA cable connections

For various reasons out of my control, we have wound up in a situation where we have 1.5mm SWA cables buried in these pillars and exiting out of the plastic housing for the wall lights.

There are around 5 of these lights across the 5 pillars. Daisy chained with the 3 core SWA. As you can see, the wall ha snow bene plastered and finished. The house-end of this cable will be glanded into a Wiska box and punched into the house to connect to a Switched FCU.

The plastic housing set in the pillar is only deep enough to take the light!

The back of the plastic box has some screw holes for the light to fix to.

I am at a loss as to how I get these cables connected to the lights given the lack of space and hence, inability to gland these ends. If this were regular T&E it wouldn't have been an issue - from a space and connectivity point at least!

Can I please have some creative suggestions on how I get myself out of a hole. Thanks in advance.
 
I did contemplate that. We now have 5 of the recessed lights which weren’t particularly cheap and can’t be returned as I have used the back box…
I did like the idea of recessed lights.
These can be had for sub £10 each, the ones i used were about 10mm deep thats all so barely stood off. Thats
I have been reflecting on this and this is probably my best option. New surface lights can be very slim and not the bulkheads I initially had in my mind when considering this option. There also reasonably priced. Something like this may be:

Does the housing space give me enough room for a mini wiska and 2 regular glands in your view?

Just compare depth of those wiska boxs with what youve got in the wall, looks deep enough from photos, it's going to be fiddly but looks doable.

This is a recessed fitting like you have already, cpc sell theirs or the eterna ones arent too bad, id think the wiska box will fit, measure the depth you have

The plastic housing is a brick's width/height and 7.5cm deep.
A mini wiska box is 64mm deep/high.

This doesn't leave enough room for the SWA glands if I try to insert them from the same end. Am I missing something?

In one end out the other, and use the brass single earth bars to pick up the armouring, probably dont need cw glands if you seal the light infront of it
 
Why are you titting around with glands, just treat the SWA as flex and terminate it as you would, if the SWA cable is in the wall cavity then it doesn't need the SWA protection anyway and it will still be armoured, just not earthed. The piece coming from the house or wherever can still be glanded I presume so that will satisfy the buried cable regulation.

When we wire brick lights, we just put in copex first and pull the flexthrough as we are doing the brick lights, it doesn't need any more than that.

Now that is something I thought but dared not mention! From a practical point of view this would work and I can unsheath the cores, cut away the metal lining and slip straight into the light but thought that wasn't allowed? Do SWA cables not always have to be glanded? Also, will your approach risk the cores being damaged by the metal strands?

The house end is glanded and earthed.

Thanks for your support.
 
I don't see a problem with it myself, maybe if you want to be super spark and do everything strictly by the book then maybe it should be terminated properly, but from a safety perspective, it will be absolutely fine, how is the flex terminated in these fittings, is it a pinching/stuffing gland and is there an in and out. In the past I've drilled a 20mm hole in these to add an extra stuffing gland when its only come with one.

Here are pics from the back. It has a single entry point. It's got a rubber grommet.
Your suggested approach will mean that I cut back the outer, inner sheaths and metal strands (as deep as I can into the plastic housing). I can then push the two sets of L, N through this grommet and connect into the light. Perhaps I should put the two CPC's into a wago to maintain continuity?

What is on the other side of the wall.

That sounds like a total bodge I'm afraid to say. Personally I think you are in a no win situation unless you can enlarge the hole or terminate the cables on the other side of the wall.

Not quite if you cut the armoured bit back quite far you are left with the inner bit which is just like flex, although the sheath is a bit on the thin side, I was suggesting fit two stuffing glands into the light somewhere and clamp these onto where you cut the armoured strands so they are just inside the gland. Even if it was wired in flex I wouldn't trust that grommet to keep the water out, especially with two cables in it.

there must be room for a couple of small stuffing glands on that fitting somewhere, The last bit of 1.5 SWA I used was as thin as a piece of flex anyway.
 
Is there a reason why some space could't be made above or below the light? This question has been asked more than once, but I don't see any meaningful response.

10 min per light with an SDS and cables could be made off properly, then a bit of Tuff sheath or HO7 brought through the rear in a single stuffing gland.

It would be as easy to do this right as mess about with less than ideal 'solutions'.

The armour must be earthed.
