Hello,

Do fire rated downlighters prevent moisture egress? I would like to
add some downlighters in the bedroom ceiling but would be reluctant to
do so if these would increase the possibility of moisture escaping to
the loft.

I have some old R63 type downlighters in the bathroom and I'm sure
these are part of the cause of loft condensation when it is really
cold outside.


Thanks,

Graham

well mine have a sealed front "bezel" (with glass) that is a very
tight bayonet fit into the lampholder part - i.e. a vast vapour
improvement over open fronted ones that create a "chimney" effect
directing steam etc up around the bulbs...

Are Zone 1 "shower proof" fittings similarly constructed? (at least in
the glass fronte bezel department?)
