In order to ensure that the LED ceiling lamp is fixed firmly and reliably, and its service life can be extended.
(2) When using expansion bolts to fix, the bolt specifications should be selected according to the technical requirements of the product, and the drilling diameter and embedment depth should be consistent with the bolt specifications.
