2081120 9215821 PCTABS00016 An adjustable lighting fixture has a power transfer means interposed between a lamp holder and the point of mounting. The power transfer means has an input shaft, which may be offset from the point of mounting, such as a fixture mounting pole, or in line therewith, and an output shaft which rotates in response to the rotation of the input shaft about its own axis. When the axis of power input is in line with the point of mounting, a physical rotation of the power transfer means will cause the rotation of the lamp holder about an axis extending through the point of mounting. When the axis of power input is offset from the point of mounting, an orbital input about the axis of the power input, or in other words an orbiting of the power input shaft about the axis extending through the point of mounting, will cause rotation of the lamp holder about said axis extending through the point of mounting. In a modification of the invention, a recessed adjustable lighting fixture is provided where an offset power transfer means is connected to a housing for rotation. The offset power transfer means has a single axis or node of power input to produce rotation of the lamp holder about two axes of rotation.
