Just got my Screwfix mains halogen showerlight, and the 'destructions' tell 
me that a wood ceiling is not suitable. (Curses!) So what is - ordinary 
plasterboard? And just how hot do these things get?

I have similar Q ?
the downlighters (low voltage ones) are blimmin hot in my ceiling and the
loft has the
insulation pulled away about 30cm all around each one,
still smells of burning up there when they are switched on.
What is the safe method of install and can you board over the top safely ?

I know it looks naff...but leave them uncovered..and don't ever board over 
them if your having a loft extension!
