Proposal is to insert LED downlighters into the kitchen ceiling (replacing old central lights). The attic is immediately above the ceiling with a good thickness of rockwool (c250mm).
LEDs are semiconductor devices, so are heat sinks required to control temperature rise?
ISTM that plasterboard is an unlikely heatsink. Also I'm uncertain about fire hoods are the answer. ISTM that a method of generating a flow of air is needed.
TIA for any suggestions.
