A fire resistant / fire proof lighting fitting 1 intended to be mounted in a panel 3. The fitting includes a body 4 in which a lamp may be mounted. The body 4 includes one or more ventilation apertures 8 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 passage of flames from the interior of the body to the exterior of the body. The ventilation apertures may be formed by parallel horizontal elongated slots in the body. The or each ventilation aperture 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. |
