Thank you for your question. The manufacturer does not list the exact diameter of the center hole. It is designed to work with standard ceiling fixture hardware used in many flush mount fixtures. In many installations, the center hole isn't even needed, as the light engine can be mounted using the built-in magnets on compatible steel fixtures or the pre-drilled mounting holes for screw installation. This provides several mounting options to accommodate a wide variety of existing fixtures.
