Downlights with flex help

Do I have to use heat resistant flex (will be led lamps)
Probably not - it looks like there is a terminal block that's slightly remote from the lamp housing. but you must follow whatever the MI (Manufacturer's Instructions) say.

That fact that you are using LED lamps doesn't matter - because you cannot guarantee that no-one will fit a halogen bulb which will run considerably hotter.
Its this one now top of the list http://www.icage.co.uk/

So one says use separate junction box and then heat resist flex and the other says ok to use existing twin and earth standard flat loop in and out

I have spent the last few weeks on a job where those ansell icage lights are being used throughout.

You can get two twin and earth in the terminals quite comfortably, you just need to strip a few mm more sheath off than you'd expect and give the live and neutral a good bend (give them a dog leg/I don't mean twist them), putting the earth in first.

Imperative you screw the connector to the fitting as that's how the landholder is earthed

Thanks for that, I am looking at those because if I want to I think I can get some extra long higher power leds in there as I think the can section is quite long, what did you think of them

Also the ca body measurements state 68mm and I suppose you need to add a few mm for the springs but it says a cut out of 85mm on the ip65 ones is needed - seems a bit big
 
They're not too bad. I'll have a look later and see what size holesaws we've been using if I remember. I think we've been using 74mm for the standard ones not 80mm like the manual says

That would be great, my issue is that I have been down this road before with some click flameguard like these http://www.fastlec.co.uk/click-flameguard-recessed-low-glare-downlighter-240v-mains-g[/url]
As at the time LEDs were not good enough and I wanted something that would take an 11w megaman and sit flush.
So Im now left with 90mm holes, now in my new ceiling I want to keep the hole as small as I can to allow future replacements and those icage holes seem a bit on the big side compared to others.

I see that you are also looping in and out with standard flat T+E for regs also then

What do the MIs state ?
Looking at the phot, then it's probably OK - the terminal box is "remote" from the heat source to the extend that it isn't likely to be an issue. There's a "pigtail" of what will almost certainly be high temperature flex between the lampholder and the terminal box, so that takes care of the most important bit (the hot end of the bulb heating the lampholder).
 
If the cpc's are twisted together underneath the JB, that does not sound like an installation from 1998.

That practice predates the 90's by a long shot.

Unless the guy that did it was long in the tooth.
 
A guy nearing retirement in 1998 would have served his apprenticeship with an electrician who himself qualified before WW II.

Old habits sometimes die hard.

Indeed - that's what I said above. When I moved into this house in 1987, it was full of JBs wired like that, but they had probably been installed in the 70's, or maybe even 60s. Some did at least have the twisted CPCs in some sort of connector block. Electrically speaking, I suppose there was not a lot wrong with the practice - the main problem was that it usually either left bits of bare CPC within the JB (there was never any sleeving) or else the outer sheath of the cable did not fully enter the JB.

Yea we're using the same holesaw size for the IP as they recommend. Sorry.

Also, if you look at page 6 of their catalogue, it better illustrates what I was trying to describe about the bending of the conductors.

Did a couple more today and remembered another tip, bend the connector strip up to 45degrees, makes life MUCH easier

Yeh thats what i am seeing, at least at this JB anyway which was why I mistook it for no earth because from the top I can just see each red and black, but the earth is pulled around the back so tight and neat that from above I could not see any, its only when i picked the JB up and turned it over that I could see all the earths.
I dont even think the rest of the JBs up there are all like it-- and for what its worth due to various extensions the whole house has been tested (ring and downstairs lights) and I have certificates for ---all except the upstairs lighting everything else was ok when tested and I have no reason to doubt the upstairs lighting, caveats and warnings not withstanding

Yes I saw that too and thought of you
What I dont get is that both ip and non ip ones have the same body diameter {68mm) yet the ip rated one needs a 85mm cutout and the non needs a 76mm
 
Not too sure tbh but the overall diameter is 105mm or whatever so no worries cutting the hole. You could always do a test hole on an old bit of wood and see how it looks/fits etc.

In the first post you said these were for a bedroom? So just don't fit the IP rated ones and use the standard ones?
 
Yeh the holes are bigger than usual though arnt they even at 76mm ive always got in the back of my mind future replacements and at 76mm limits my choice.

Sounds like you are fitting ip ones as they are 108 at the bezel with an 85mm cutout

I think I am going to take a piece of board to the suppliers with a few different smaller holes to see what I can get away with.

So you are looping in and out with normal non heat resist 1.5mm T+E then on these
