The lighting fixture includes a fixture body including an elongated shape, a first end, and a second end. First and second body mounts are connected to the fixture body and configured to be mounted on first and second lighting ducts. A light source is accommodated in the fixture body and configured to emit laser light. A power supply is accommodated in the fixture body and electrically connected to the light source. A light guide includes an entrance end and an exit end. The entrance end is optically connected to the light source. The light guide is configured to guide the laser light from the light source to the exit end. A lamp is attached to the fixture body and optically connected to the exit end of the light guide. ## Claims ### Claim 1 A lighting fixture, comprising: a fixture body including an elongated shape, a first end, and a second end;
