ABSTRACT:
A portable task lighting device which comprises an elongated fluorescent light assembly that casts a broad, glare-free, and cool flood of light and is rotatably connected to the distal end of a boom arm for a full 360.degree. of rotation. Its boom arm can be fixed into a plurality of positive locking positions both above and below the top of its mast by adjustment of a pivot block supported by the mast. The preferred embodiment of the lighting device has a telescoping mast with a square cross-sectional configuration. The mast supports the proximal end of the boom arm and provides extension between approximately thirty-two and ninety inches. The mast is supported by a base assembly having two shorter rear legs which are adjustable laterally relative to one another and two elongated front legs which are locked into position at a predetermined stationary angle by insertion of the mast within a square opening through the top of the base assembly. Thus the lighting device of the present invention is adjustable into an infinite number of positions, and in addition it is configured to be quickly and easily collapsed into a compact configuration by the removal of one quick-release pin and the loosening of several quick-release clamping devices that secure the mast and rear legs in place during use. Applications may include, but are not limited to, use for a wide variety of light-sensitive work projects that for proper completion require a direct source of shadow-free lighting.
