LIGHTING FIXTURE Abstract of the Disclosure A lighting fixture adapted to be mounted on a ceil- ing by attachment to an outlet box in the ceiling. The fix- ture comprises a pan having a bottom and a rim engageable with the ceiling for spacing the bottom of the pan therefrom, a crossbar attached to the bottom of the outlet box in position extending horizontally across the bottom of the box, and fas- teners for detachably securing the rim of the pan to the crossbar. The lighting fixture also includes a first layer of insulation in the pan secured to the pan above the bottom thereof, a second layer of insulation secured on the underside of the bottom of the pan, and a light socket for mounting a light source on the underside of the pan below the second layer of insulation. A diffuser having an open top is mounted on the underside of the pan around the socket and the light source. The second layer of insulation is disposed above the light source for thermally insulating the light source from the pan and the outlet box to reduce the transfer of heat gen- erated by the light source to the outlet box.
