I'm planning to install GU10 recessed light fittings into an insulated
(rockwool maybe sheeps wool?) ceiling (the insulation will be there
primarily for acoustics but the thermal insulation will be useful).
The lights will be in a shop, our flat is above.

I know there are fire hazzards associated with using the halogen
GU10's (either low voltage or 240V) and you need to fit fire hoods,
cut away the insulation etc - but if i'm fitting megaman GU10 CFLs
will this still apply? The heat output would be much less... would
Building Control still insist on fire hoods since in theory halogens
could be fitted?

Ideally i'd like to use LEDs but from what I've seen/heard the bulbs
aren't quite up to it yet.

If your ceiling is fire rated you will need firehoods or fire rated
fittings. Firehoods are to stop the spread of fire through the ceiling from
one level to the next however the fire is caused, not to protect against
halogen lights catching fire.

I recently fitted some firerated GU10 fittings and they are a lot easier to
work with than the fire hoods.
