Provided is a lighting fitting intended to be mounted in a panel. The fitting includes a body in which a lamp may be mounted. The body includes one or more ventilation apertures which are sized and configured to allow heat generated by a lamp in the body to be adequately vented to the exterior of the body, but to inhibit the passage of fire from the interior of the body to the exterior of the body. The one or more ventilation apertures may be formed by a slot in the body. The one or more ventilation apertures may be configured so that when the fitting is installed in its intended orientation, an at least partially downward path is defined between the interior and exterior of the body of the fitting through the aperture.
