Abstract: An apparatus and method for keeping a high intensity discharge arc tube relatively horizontal in a light fixture regardless of aiming orientation of the light fixture towards a target. In one aspect, the light source is mounted in an independently pivotal yoke in the light fixture. A gearing arrangement automatically proportionally pivots the light source relative to any pivoting motion of the fixture over a range of motion such that a selected light source orientation can be approximately maintained regardless of aiming orientation of the fixture.

Abstract: An apparatus and method for providing a temporary spread footing for supporting a variety of different vertically extending structures. The apparatus includes a frame with a top and bottom. The frame can have a substantial space or void in between the top and bottom into which weights or devices can be placed. A connection on top of the base removably connects to the structure to be supported. Outriggers could also be used to substantially increase the overturning moment resistance of the base. The outriggers can be removable or retractable so that for transportation, the base has minimum dimensions. The method includes pre-determining the needed weight and overturning moment resistance for a particular application and transporting the base to the site and thereafter adding weight and adjusting outriggers to match the pre-determined needed overturning moment resistance.
