The boom arm (2) is displacable to a limited extent in all directions. To simplify manipulation of the light the, boom arm (2) consists of at least three equal rods (4) that are parallel to each other; all of the rods (4)are hinged onto the base (1) and the light (3) so as to be pivotable through a spherical range of movement. Connections prevent the rods (4) from twisting relative to each other.
