An illumination system, particularly adapted to use in hospitals, has an elongated, low-profile fluorescent lighting fixture on the side of and parallel to a track, a reading-examination light mounted on one end of a telescoping boom, the other end of which is swingably connected to a boom mount rotatably carried by a carriage mounted to roll along the track. The lighting fixture includes means for providing low brightness down lighting and higher brightness side lighting. The reading-examination light is so constructed as to permit two levels of illumination from a single light source and color correction in a small, balanced, easily manipulated unit. The telescoping boom and its mounting are so constructed as to be light, strong and stable in any position within wide limits. The carriage is so constructed as to permit easy transport of the boom and light, and positive and continuous connection of electrical conductors within the boom to a source of current.
