Large Low Profile LED Round Flush Light for Wall or Ceiling Dia 550mm

Hi, We are looking to install these wall lights in a Listed Building and so have to use MICC cable for glanding. Will these fittings fit onto a galvanised conduit box with 4mm brass screws for back entry installation where the cable entry would be?
Termination Strategy Rather than terminating the MICC directly into the rear entry of the fitting, the best practice is to: Terminate the MICC into a metal adaptable box (galvanised or stainless steel) positioned close to the rear of the fitting—ideally fixed to the same mounting surface. From that box, run a short tail of heat-resistant flex (such as 1.0mm² or 1.5mm² silicone-sheathed cable or fibreglass-insulated wire) through the rear entry and into the light fitting as per the original design. This approach has several benefits: Prevents strain on the fixture from the rigid MICC. Keeps heat and the gland away from the plastic diffuser. Maintains fire-rated circuit integrity up to the adaptable box. Allows standard termination inside the light fitting using conductors appropriate for the terminal block and space. Glanding Considerations If you absolutely must bring the MICC directly into the back of the fixture: Ensure there's enough flat steel area for the gland to seat securely. Use a backnut inside the fitting to secure the gland (if space allows). Earthing The MICC copper sheath provides CPC continuity. Connect it securely to the earth terminal in the steel body.
