5. The lighting assembly of claim 1 , wherein

said ceiling pan includes at least one sight window; and

said lamp assembly includes at least one indicator, said indicator being visible through said sight window to align said lamp assembly visually to a predetermined position with respect to said ceiling pan.

6. The lighting assembly of claim 1 , wherein said lamp assembly comprises

at least one lamp support and a lamp coupled to said lamp support, said support and said lamp being adjustable about a vertical axis and about a horizontal axis with respect to said lamp assembly.

7. The lighting assembly of claim 6 , wherein said lamp assembly further comprises

a support bracket coupled to said base for supporting said lamp support, wherein said support bracket is positioned to contact two adjacent hold down members to limit the rotational movement of said lamp assembly.

8. The lighting assembly of claim 1 , wherein said lamp assembly further comprises

a pair of lamp supports receiving a lamp for directing light through said opening in said base and said opening in said ceiling pan, each of said lamp supports having an adjustment assembly for adjusting the position of the respective lamp about a vertical axis and about a horizontal axis.

9. A lighting assembly comprising:

a ceiling pan adapted for coupling to a ceiling support, said ceiling pan having a substantially planar bottom wall with a centrally located opening to enable light to be directed to a target area;

a lamp assembly having a base mounted on a top surface of said bottom wall and having a centrally located opening aligned with said opening in said ceiling pan, a sleeve extending from an edge of said opening of said base and adapted for extending into said opening in said ceiling pan, said lamp assembly being rotatable and transversely adjustable with respect to said ceiling pan;

at least one hold down member on said ceiling pan for limiting vertical movement of said lamp assembly with respect to said ceiling pan; and

a locking member on said lamp assembly for engaging said ceiling pan to fix the position of said lamp assembly with respect to said ceiling pan.

10. The lighting assembly of claim 9 , further comprising

a plurality of said hold down members on said ceiling pan and spaced apart around said opening in said ceiling pan and having an end overlying a top surface of said base, and where said locking member is movable to a locking position to move said base into engagement with said hold down members to fix the position of said lamp assembly with respect to said ceiling pan.

11. The lighting assembly of claim 9 , wherein

said locking member is movable to a locking position to move said base into engagement with said at least one hold down member to fix the position of said lamp assembly.

12. The lighting assembly of claim 11 , wherein

said locking member includes a pivotally mounted arm and a brake member, wherein said arm is pivotable to said locking position to contact said brake member and move said brake member downwardly into engagement with said ceiling pan.

13. The lighting assembly of claim 12 , wherein

said locking member includes at least one cam member engaging said brake member and where said brake member includes a locking spring.

14. The lighting assembly of claim 13 , wherein

said brake member includes a base plate coupled to said base of said lamp assembly, and where said locking spring extends from said base plate and is spring biased in a direction away from said ceiling pan.

15. The lighting assembly of claim 14 , wherein

said locking spring has a detent for engaging said cam member on said locking member.

16. A lighting assembly comprising:

a ceiling pan adapted for coupling to a ceiling support, said ceiling pan having a bottom wall with an opening therein to enable light to be directed to a target area and a sight window spaced from said opening in said bottom wall;

a lamp assembly having a base mounted on a top surface of said bottom wall, said base having an opening therein aligned with said opening in said ceiling pan, said lamp assembly being movable in a transverse direction with respect to said ceiling pan, a lamp coupled to said base for directing light through said opening in said base;

an indicator on said base and being visible through said sight window for aligning said lamp assembly in a predetermined position with respect to said ceiling pan; and

a plurality of hold down members on said ceiling pan for capturing said lamp assembly.

17. The lighting assembly of claim 16 , further comprising

two of said sight windows in said ceiling pan and two of said indicators on said base corresponding to a respective sight window.

18. The lighting assembly of claim 16 , wherein

said indicator is an aperture in said base.

19. The lighting assembly of claim 18 , further comprising

a locator spring coupled to said ceiling pan for engaging a top surface of said base.

20. The lighting assembly of claim 19 , wherein

said locator spring has a detent extending therefrom for engaging said indicator in said base.

21. The lighting assembly of claim 19 , wherein

said locator spring has a detent extending therefrom for engaging said indicator in said base.

22. The lighting assembly of claim 16 , further comprising

a locking member on said lamp assembly for fixing the position of said lamp assembly with respect to said ceiling pan.

23. The lighting assembly of claim 22 , wherein

said locking member engages said ceiling pan to move said base into engagement with said hold down members.

24. The lighting assembly of claim 16 , wherein said lamp assembly further comprises

a sleeve around said opening and extending from said base into said opening in said bottom wall, said sleeve being movable transversely and rotatably in said opening in said bottom wall.
