Sloping ceiling lights

[marsaday1971]

What sort of lights can i use in a sloping ceiling which will be filled with 75mm celotex and then 50mm under the rafter?

The attic is being converted and we dont have a flat area to place a light. We can use the wall to the left of the room and i will put a wall light here, but on the right side (sloping) the shower will fit into here.

Can the lights go near to the shower as well ?

i have the screwfix catalogue and have noticed some led lights which are 45mm deep. Are these ok? The depth to the tile in the rafter is 100mm.

You can get spot lights that are directional which may move enough to get the desired effect.

With regards to the shower light. You can have a light inside the shower tray so long as it is of the correct IP rating

Sorry mate I think recessed lights are out the question, I think you will need to use surface fittings, and as for the shower question, that will depend on which zone it comes under as to which IP rating is required (if any).

sometimes the building inspector wont like the recessed lights in the sloping ceilings, something to do with breaking the thermal barrier on the celotex, i have had situations where i didnt have a choice but i got away with it! depends if hes being ---- or not

aswell as having clearance behind the light!

The reason I said no, was because recessed fittings require a bit of ventilation for the heat to discipate and if they are surrounded by insulation then this cannnot happen.

Ok here is some more info for you, which may mean recessed lights are ok.

The depth from plasterboard front to the tile at the back is 165mm.

I have no breather membrane on the roof, just tile. So behind a light of say 100mm depth will be a gap of 65mm venting onto tile. So there will be plenty of ventilation.

The BC officer is pretty relaxed about cutting a hole for 2 lights in the bathroom. This is all i will be using for the whole attic area.

I thought you could use those led lights and wondered what anyone thought about them?
