A lamp (5) is secured to the end (4) of a support arm for at least horizontal translational movement, and is pivotable about a vertical axis (10) for azimuth adjustment of the light beams from lenses (82,83). To facilitate such horizontal movement by a handle (15), the handle is disposed on or adjacent the vertical pivot axis (10). The lamp which may also be pivotable by the handle (15) about a horizontal axis (11), is preferably located substantially entirely on one side of the vertical axis (10). |
