We claim: 1. A luminaire for use with a bulb, comprising: a housing; an orientation ring supported by the housing, wherein the orientation ring is supported by a sleeve, and the sleeve includes a plurality of teeth; a rotation drive unit that rotates the orientation ring with respect to the housing so as to adjust, in operation, the rotational orientation of the bulb, wherein the rotation drive is actuatable by rotation of a first member, further wherein the rotation drive is mounted to the orientation ring and includes a pinion that engages the plurality of teeth, whereby the rotation drive and the orientation ring is translated with respect to the sleeve by operation of rotation drive unit; an aiming frame supported by the orientation ring; a bulb holder pivotally mounted to the aiming frame and configured to receive the bulb; and a bulb holder drive that rotates the bulb holder about the pivotal mounting so as to adjust, in operation, the angular orientation of the bulb, wherein the bulb holder drive is actuatable by rotation of a second member, wherein the rotational and angular orientation of the bulb is adjusted while the bulb is on and when the bulb is off. 2. The luminaire of claim 1, wherein the actuation of the rotation drive and the bulb holder drive element is done either separately or simultaneously. 3. The luminaire of claim 1, wherein the sleeve is adjustably mounted to the housing. 4. The luminaire of claim 3, wherein the sleeve is infinitely adjustable within a predetermined range with respect to the housing. 5. The luminaire of claim 4, wherein the bulb holder comprises a tray system with an upper tray configured to support the bulb and a lower tray that supports the upper tray, the upper and lower tray being urged together by a biasing element. 6. The luminaire of claim 4, wherein the sleeve is infinitely adjustable over a range of thicknesses between about one half of an inch and one and five eights of an inch. 7. The luminaire of claim 1, wherein the aiming frame includes a first arm for supporting the frame in an installed position and a second arm for supporting the frame in a bulb changing position, wherein the frame is translatable between the installed position and the bulb changing position. 8. The luminaire of claim 1, wherein the bulb holder includes a tray for supporting the bulb and an arm configured to hold the bulb in a first position on the tray. 9. The luminaire of claim 8, wherein the tray is an upper tray configured to support the bulb and the bulb holder further comprises a lower tray that supports a lens in a first orientation between the lower tray and the upper tray, wherein the bulb is removed from the upper tray without affecting the orientation of the lens. 10. The luminaire of claim 1, wherein the frame includes an opening configured to support a wire.
