and an adjustment assembly for adjusting the angular position of said lamp support. ### Claim 2 (depends on 1) The light assembly of claim 1, wherein said bracket is rotatable about a vertical axis with respect to said base. ### Claim 3 (depends on 1) The light assembly of claim 1, further comprising; a frame coupled to said base and extending in an upward direction with respect to said top surface of said base, and said bracket being coupled to said frame and pivotable about a vertical axis with respect to said base. ### Claim 4 (depends on 3) The light assembly of claim 3, wherein said adjustment assembly comprises; a gear pivotally connected to said bracket, and where said lamp support includes a plurality of teeth meshing with said gear so that rotation of said gear pivots said lamp support with respect to said bracket. ### Claim 5 (depends on 3) The light assembly of claim 3, wherein said adjustment assembly comprises; a locking member to fix the position of said bracket with respect to said frame. ### Claim 6 (depends on 5) The light assembly of claim 5, wherein said locking member of said adjustment assembly fixes the position of said lamp support to said bracket. ### Claim 7 (depends on 6) The light assembly of claim 6, further comprising; a locking screw coupled to said bracket, and where said locking screw moves said locking bracket into engagement with said frame to prevent rotation of said bracket with respect to said frame. ### Claim 8 (depends on 7) The light assembly of claim 7, wherein said frame includes at least one aperture for receiving said locking member to lock the position of said bracket. ### Claim 9 (depends on 7) The light assembly of claim 7, wherein said locking screw is received in a threaded aperture of said bracket, wherein tightening said locking screw actuates said locking member into locking engagement with said frame and locks the position of said lamp support to said bracket. ### Claim 10 (depends on 9) The light assembly of claim 9, wherein said locking member includes a cam follower and where said locking screw actuates a cam to move said locking member into engagement with said frame. ### Claim 11 An adjustable light assembly comprising: a base having a central opening and a frame with an upper end spaced from a top surface of said base; a bracket coupled to said upper end of said frame and being pivotable about a first axis substantially perpendicular to a plane of said base and substantially parallel to a central axis of said opening in said base, said bracket having an arm extending toward said base; and a lamp support coupled to said arm of said bracket and being pivotable about a second axis substantially perpendicular to said first axis. ### Claim 12 (depends on 11) The light assembly of claim 11, wherein said lamp support is coupled to said bracket by a pivot member to pivot in a plane parallel to a plane of said arm of said bracket, said light assembly further including an adjustment mechanism. ### Claim 13 (depends on 12) The light assembly of claim 12, wherein said adjustment mechanism includes a rotatable gear on one of the bracket arms or lamp support and a plurality of teeth engaging the gear on the other of the bracket arm or lamp support, whereby rotation of the gear pivots said lamp support with respect to said arm. ### Claim 14 (depends on 12) The light assembly of claim 12, wherein said adjustment mechanism includes a gear rotatably mounted on said arm of said bracket, and where said lamp support includes an elongated slot with inwardly extending gear teeth, said gear being received within said slot and mating with said gear teeth, whereby rotation of said gear pivots said lamp support to a selected position. ### Claim 15 (depends on 11) The light assembly of claim 11, further comprising; a locking assembly to fix the position of said bracket with respect to said frame and to fix the position of said lamp support with respect to said bracket. ### Claim 16 (depends on 15) The light assembly of claim 15, wherein said locking assembly includes a locking member coupled to said bracket and is movable to engage said frame to fix the position of said bracket with respect to said frame. ### Claim 17 (depends on 16) The light assembly of claim 16, further comprising; an actuator to engage and move said locking member into locking engagement with said frame. ### Claim 18 (depends on 16) The light assembly of claim 16, further comprising; a screw received in a hole in said bracket and extending through a hole in said lamp support, wherein said screw is tightened to fix the position of said lamp support with respect to said bracket and to move said locking member into engagement with said frame. ### Claim 19 (depends on 18) The light assembly of claim 18, further comprising; a cam member with a threaded hole receiving said screw, said locking member having a cam follower engaging said cam, whereby tightening said screw moves said cam to move said locking member into engagement with said frame. ### Claim 20 (depends on 16) The light assembly of claim 16, wherein said frame includes at least one aperture for receiving an end of said locking member to fix the position of said bracket to said frame. ### Claim 21 (depends on 16) The light assembly of claim 16, wherein said frame includes a plurality of holes defining predetermined positions of said bracket, and where said locking member includes a tip at an upper end thereof for engaging one of said holes to fix the position of said bracket to said frame. ### Claim 22 An adjustable lighting assembly comprising: a base having a bottom surface and a top surface; a frame coupled to said base and having an upper plate spaced from said top surface of said base; a bracket coupled to said upper plate of said frame and being pivotable about a first axis substantially perpendicular to a plane of said base; a lamp support pivotably coupled to said bracket and being pivotable about a second axis substantially perpendicular to said first axis; an adjustment mechanism coupled to said bracket for adjusting the position of said lamp support with respect to said bracket; and a locking mechanism for fixing the position of said lamp support to said bracket and for fixing the position of said bracket with respect to said frame. ### Claim 23 (depends on 22) The lighting assembly of claim 22, wherein said adjustment mechanism includes; a gear rotatably coupled to said bracket, and where said lamp support includes a plurality of teeth engaging said gear, whereby rotation of said gear pivots said lamp support with respect to said bracket in a plane substantially parallel to a plane of said bracket. ### Claim 24 (depends on 23) The lighting assembly of claim 23, wherein said locking mechanism comprises;
