A height adjustable mobile illumination apparatus for a greenhouse comprising a horizontal track (1) that is longitudinally aligned with the greenhouse. The track is vertically adjustable and is suspended, from the greenhouse by a first set of cables (2). An illumination means is mounted to the underside of the track and is mobile along the length of the track by operation of a second set of cables (20). A drive system (30, 31) is used to operate the first and second sets of cables. The height of the illumination means above the plants is adjusted by raising the entire track with the first set of cables. A plurality of illumination means may be provided on a single track spaced apart along the length of the track. A system for illuminating an entire greenhouse comprises a plurality of the apparatus as previously described arranged in spaced apart relation across the width of the greenhouse. |
