This weekend I'll be fitting some LV halogen downlighters in the
bathroom. So I'll be cutting holes in the ceiling into the attic
which is currently insulated with 200mm of rockwool.

Can I leave the downlighters underneath the insulation or should I
remove the insulation above the downlighters to prevent heat build up?
Maximum lamp wattage will be 35W.

Thanks

Stick a traditional flower pot over each on. That will allow some heat
to vent and stop them getting smothered in insulation.

Hi,

Also use NON dichroic bulbs if you want any heat from the bulb to go
down into the room and not heat the ceiling/loft.

cheers,
Pete.

They should be sealed boxed in above the light to stop the damp from
the bathroom going up their and rotting the roof timbers. You can
leave the insulation above the box the heat can dissipate downwards
into the room. Use plasterboard and fire proof mastic to construct the
box.

Someone's been watching too much facile TV. Reasonable striplight(s) if
a large room or if smaller, a ceiling located CFL is adequate.

What I choose to install in my own bathroom is not your concern. If
you wish to post some useful advice on installing downlighters then
please go ahead. Otherwise f*ck off, muppet.

Almost about all the downlighters you can buy are designed to dump
the heat above the ceiling. Don't do this with one of those.

If you were particularly concerned about compromising a fire break, then
there are products that address this as well:

Not wanting to get this wrong so what size?

I've got some 50W in the bathroom and kitchen ceilings that seem to
attract woodlice which are subsequently grilled on the glass cover after
falling into the fitting!

Its not that critical - a terracotta flow pot won't melt, and has a hole
in the top. So long as it is big enough to cove the back of the fitting
with a bit of space to spare it will allow some heat to escape.

Make the eclosure big enough and it wont be a problem.
