a base, the cylindrical intermediate body rotatably attached at the intermediate lower opening to the base, the base comprising a light emitting opening for emitting light from the light module.

2. The luminaire of claim 1 , wherein the cylindrical upper body and the cylindrical intermediate body are centered about an offset axis.

3. The luminaire of claim 2 , wherein the light module and the base are centered about a pivot point axis that passes through a pivot point located at the light emitting opening.

4. The luminaire of claim 3 , wherein the cylindrical upper body directs light along the light emitting axis to the pivot point at any angle of rotation of the cylindrical upper body.

5. The luminaire of claim 3 , wherein the cylindrical upper body can direct light at a light emitting angle ranging from 0 degrees to 35 degrees, wherein the light emitting angle is an acute angle between the light emitting axis and the pivot point axis.

6. The luminaire of claim 2 , wherein the cylindrical intermediate body is rotatable about the offset axis.

7. The luminaire of claim 1 , wherein the upper angled opening defines an upper plane forming an acute angle of approximately 17.5 degrees with the upper wall where a height of the upper wall is greatest.

8. The luminaire of claim 7 , wherein the intermediate angled opening defines an intermediate plane that is parallel with the upper plane and that forms an acute angle of approximately 17.5 degrees with the intermediate wall where a height of the intermediate wall is greatest.

9. The luminaire of claim 1 , wherein the cylindrical upper body further comprises a tab on an inner surface of the cylindrical upper body for adjusting a light emitting angle and for locking the cylindrical upper body in place.

10. The luminaire of claim 1 , wherein the cylindrical intermediate body further comprises a tab on an inner surface of the cylindrical intermediate body for adjusting a direction of the light and for locking the cylindrical intermediate body in place.

11. The luminaire of claim 1 , wherein the cylindrical upper body further comprises an elongated heat sink fin, and wherein the cylindrical intermediate body, further comprises a stop tab located on a top edge of the cylindrical intermediate body, the stop tab disposed to engage the elongated heat sink fin when the cylindrical upper body is rotated to a specified position.

12. The luminaire of claim 1 , wherein the base comprises:

a pivoting clamp wing; and

a foot clamp, wherein the pivoting clamp wing and the foot clamp are configured to secure the base to a ceiling.

13. The luminaire of claim 1 , wherein the base further comprises a series of dimples that increase the surface area of the base.

14. The luminaire of claim 1 , wherein the cylindrical upper body further comprises a recess in the upper wall into which the cylindrical intermediate body fits.

15. The luminaire of claim 1 , wherein the cylindrical intermediate body further comprises a recess in the intermediate wall into which a slip plate fits.

16. The luminaire of claim 1 , further comprising:

a slip plate mounted on the base, the slip plate configured to support one or more retention brackets; and

a base flange for securing the luminaire against a ceiling.

17. A luminaire comprising:

a cylindrical upper body comprising an upper wall of varying height and a light module, the upper wall forming an upper angled opening, the light module configured to emit light along a light emitting axis, wherein the upper wall has a top end and a bottom end that are substantially planar, wherein the top end and the bottom end of the upper wall are antiparallel with respect to each other; and

a cylindrical intermediate body, the cylindrical upper body rotatably attached at the upper angled opening to the cylindrical intermediate body, the cylindrical intermediate body comprising an intermediate wall of varying height and a base, the intermediate wall forming an intermediate angled opening and an intermediate lower opening, the base comprising a light emitting opening for emitting light from the light module, wherein the intermediate wall has a top end and a bottom end that are substantially planar, wherein the top end and the bottom end of the intermediate wall are antiparallel with respect to each other, and

wherein the top end of the intermediate wall and the bottom end of the upper wall are parallel with respect to each other as the cylindrical upper body rotates with respect to the cylindrical intermediate body.

18. The luminaire of claim 17 , wherein the cylindrical upper body and the cylindrical intermediate body are centered about an offset axis.

19. The luminaire of claim 18 , wherein the light module and the base are centered about a pivot point axis that passes through a pivot point located at the light emitting opening.

20. The luminaire of claim 19 , wherein the cylindrical upper body directs light along the light emitting axis to the pivot point at any angle of rotation of the cylindrical upper body.
