A closed luminaire that allows building insulation to come into contact its sides.
Each classification determines which type of fitting can be installed in a residential installation subject to the type of ceiling insulation and the proximity of the downlight fitting to both the insulation materials and building elements.
It is up to the electrician to determine the correctly rated fitting for the installation; considering the type of insulation installed and surrounding building materials (elements) as per diagram.

The supplier of the luminaire will have conducted tests on the luminaire in accordance with this standard and will provide in the instructions specific measurements for Risk of Fire clearances below: These specified clearances should be strictly adhered to by the installer.
side clearance to building elements
height clearance to building elements
side clearance to building insulation
minimum ventilation clearance above building insulation
Note: Loose fill insulation is not permitted to abut or cover the luminaire unless specifically allowed by the luminaire manufacturer.
