I am absolutely sold on the whole vcl / draught proofing idea. Makes SO much difference. Ok, i get that. But why not just foam it in? Once you trim it back flush with the top of your insulation, maybe even stick some foil over it surely that as good as it gets?

I am going to "just foam it in" but additionally stick the Thermahood down so no foam can get under the Thermahood into the light cavity. The vcl should then be a continuation of green plastic/intumescent seal/Thermahood/intumescent seal/green plastic. I don't trust my cutting of the PIR between the joists to be that "airtight". Just got some Adaptaflex and M20 glands so must figure bringing that up to the conduit boxes. Making the conduit airtight around the cables (in the conduit) once in I'll do with Wiska gel. Saying that I think the Adaptaflex is air leaky! 1

I paid £12 ea for these: https://www.ledbulbs.co.uk/enlite-e8-8w-fixed-dimmable-fire-rated-led-downlight-cool-white So IP65, fire rated & with a seal. But...the seal on these (or any other downlights) is no way as good as the vcl I've punctured to fit them. I'm trying to create a cavity whereby the vcl is reinstated as best as I can. The vcl will be the Thermahood. You can get airtight on commercial grade down-lights, most of the tin bashed stuff from China isn't up to much but plenty good for domestic use. You are looking at £120-250 for a commercial down-light that will have all the attributes you need. I have some WILA down-lights which come with all the thermal ratings and are guaranteed air tight - but at £170 a pop they are not everyone's cup of tea. Aurora are OK for domestic use - Chinese made and the chips are over-run.

They're only the thickness of the plasterboard + matchbox sized tranny, and the dispersion compared to spotlights is 10-fold better. Hi Nick - just dragging this back to the surface. I'm just insulating a vaulted area and want to minimise cutting into PIR (or at all if possible). Looking to see whether it's possible to just batten underneath the PIR, then fit the PB and simply recess into that using LEDs that have minimal height. Which 'recessed' ones have you used in the past. Something like this? https://cdn2.ledhut.co.uk/media/productattachment/1/2110/DLSLIM12WNEW.pdf
PeterW Posted June 8, 2018 Posted June 8, 2018 I’ve got something similar on site - will take a couple of photos for you. Bear in mind that 28w led will be very bright ..!!!

Hoping I can get away without faffing about on this one (VCL, cutting insulation etc). 28w - instructions from wife were "I want this area (hallway) really bright". Just following instructions. For once. Until I get the next set of instructions "These are too bright - why did you fit these???? I want something less harsh"

Thanks Dudda! I'll only have 37mm (ish) void space for the spotlights (12mm pb, 25mm batten space) so these look like an option. How hot does the one you have tested get?

TBH the 'test' mostly involved getting approval from the other half in terms of how bright it was and that she was happy with the warm white colour. The thing I like is they're waterproof so can be used in the bathrooms too.

Yeah, the only reason I asked about the temp is because I dropped my worklight this morning which dislodged the LED bulb and I noticed it was surprisingly hot. I now get the wife to write and date her decisions as 6months down the line she will either say we never discussed it or that she wanted option A, not B! 1

Onoff Posted June 12, 2018 Author Posted June 12, 2018 So the 20mm high trannie will sit in his 25mm space? How warm does the trannie get? Are there any manufacturer's instructions as to clearances?
oranjeboom Posted June 12, 2018 Posted June 12, 2018 @PeterW Thanks for the pics - that helps. I'll have to see how I can fix the LED unit into the plasterboard then as it appears it's a couple of screws 'sideways' that the bracket will slot into. Probably a couple of battens stuck to the underside of the PIR. Does each LED need a driver? And I guess they can be placed some distance from the LEDs? I was hoping to put them in an easy to get to location for future replacement rather then stuck between PIR and plasterboard.
PeterW Posted June 12, 2018 Posted June 12, 2018 Transformer was not even warm after 20 mins - these are 6w LED panels so pulling 0.03A at 230v. I wouldn't even bother screwing into anything - makes it easier to remove ..! Transformer to light is about 180mm, transformer then has 80mm tails to a supplied push fit connector.
Stones Posted June 12, 2018 Posted June 12, 2018 The ones I used were supplied with spring clips to hold the unit in position.
PeterW Posted June 12, 2018 Posted June 12, 2018 Just now, Stones said: The ones I used were supplied with spring clips to hold the unit in position. Springs are missing off the light - think @oranjeboom is referring to the transformer.

I was thinking it would be a right PIA to fit the buggers. @PeterW Did you get these from fleabay/online? If they are WA* on your side then I will be halfway correct already. *Wife Approved✔️ 1

(The other's 75mm). Enlite stuff is great imo. That's what my normal size ones are at the start of the thread. Maintenance free terminals too. Edited June 20, 2018 by Onoff
