Soffit lights, only problem is soffit is concrete

[MFS Electrical]

Concrete soffits definitely exist.
Mounting options are probably something like these...

or these...

I thought I was going mad thinking it was concrete with all the replies I’m still going to get it tested before I go all gung ho with the SDS I like both of those fittings but as there is no overhang I think I might need something a little more low profile... have you ever installed downlights on something similar?

Is it a prefab?

Not that I’m aware of mate think they were built around the 30’s 40’s and with proper bricks and mortar

I’ve seen concrete gutters before, but concrete soffits are a new one on me.

I’ve grew up round here and never thought about it till now but it definitely looks like concrete might have been old finlock type gutters the council just chopped and left

Some of the building methods up here from back in the day were crazy ever tried running a cable in a semi-supporting wall

Yes I saw that in your second pics post..
My Granny lived in a similar type of building on the other side of the Clyde from you.

That question was to your first pic . They do not look like it on second post.

It could well be a prefab as a lot of the houses round this way were built to blend in with the older ones except our lot they stand out like sore thumbs but in a good way

Clydebank? Dumbarton?

Dumbarton . Brucehill.

I might have misunderstood, but the soffit board is usually light weight, I assume that's because it's overhanging. A 50mm thick concrete slab 30cm wide (say) would weigh a ton by the time you went round the house, surely?
Edit - just seen the pics

Near the hospital? Done quite a bit of work over there too nice wee jaunt

By looking at it I do assume it weighs a ton it doesn’t look like a board at all
I’ll be taking it easy with the SDS in case it cracks and falls taking me with it

Not me personally, but believe it or not I watched someone bore a recess into the soffit then proceed to channel the cable in (unprotected, but who cares up there?). His arguement was that his recess was 150mm deep for the 80mm halogen and the heat would dissipate across the soffit. He may have been right because they were still there in Winchester last I passed (many years ago). But I never did get an answer regarding his boring of holes into a soffit every 90cm weakening it's structure. It was only 40cm wide as I recall.

When I lived there the nearest hopital was the Vale, but yes.
I was Born in the house . It was built just before WW11.

I was at first thinking of coring holes and recessing led downlights but I didn’t fancy the corer getting snagged above my head and throwing me off the ladder or the soffit raining down around me, not to mention the bill of replacing it/insurance claim

AAR! The ol' duplicate bug, it'll eat you from the inside out until you sit there all night afraid to hit that return key. Mwaaahahahah!

It's not worth the risk, seriously. Buildings that old are fragile and prone to throwing tantrums and falling apart. Don't risk it mate. Please.

Don’t worry that idea was booted out my head almost as soon as I thought of it. The customer has agreed to these fitted high up on the wall as close to the soffit as possible but I really don’t know if it’s going to be the look that either myself or the customer is after...

 

[electric will]

I think that's just a short concrete lintel

 

[Midwest]

Can I just ask, why does your customer wish to highlight the fact that they live in a slightly undesirable house. I know everyman's home is his castle, but its not like its a des res on the Sandbanks, is it
