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.
