A theatrical luminaire for entertainment and architectural applications includes a lamp socket accessible from the exterior of the luminaire housing. A lamp includes a base, a bulb on one side of the base and a handle on the other side. The handle is grasped to insert the lamp into the socket. When the base is mounted in the socket, the bulb extends through the socket into the luminaire and the handle remains accessible at the exterior of the luminaire. The lamp is mounted with a one-handed push and turn motion, and contacts on wings of the base engage socket contacts as the lamp is turned to its final position. The socket is mounted on a support that is adjustable relative to the luminaire housing to preserve the correct lamp positioning when the lamp is replaced.

A lamp assembly as claimed in claim 2 further including a lamp including a base including a pair of radially extending wings, a light source extending axially from one side of said base, and a handle on the other side of said base, said base being mounted in said lamp receiving passage of said socket assembly between said inner and outer faces, said light source being positioned at said light source location, a pair of lamp contacts mounted on said wings and engaging said socket contacts in said contact receiving cavities.5. A lamp assembly as claimed in claim 1 further including a lamp including a base, a light source extending axially from one side of said base, and a handle on the other side of said base, said base being mounted in said lamp receiving passage of said socket assembly between said inner and outer faces, said light source being positioned at said light source location.6. A lamp assembly as claimed in claim 5, said base having a radially extending wing, and a lamp contact mounted on said wing and engaging said socket contact in said contact receiving cavity.7. A lamp assembly for a luminaire having a housing with an interior and an exterior, said lamp assembly comprising:a socket supported by said housing; a lamp including a base, a light source extending axially from one side of said base, and a handle on the other side of said base; said socket including a passage extending axially through said socket to the interior of the housing; and said passage being configured to receive said light source when said lamp is inserted into said socket to a mounted position wherein said base is received in said socket, said lamp extends beyond said socket into the interior of the housing, and said handle is directed toward the exterior of the housing; and said socket including socket contacts, said base including lamp contacts, and said lamp contacts engaging said socket contacts in said mounted position; said socket including an entrance opening configured to receive said light source and said base, said passage being smaller than said entrance opening to block movement of said base and hold said base in said socket. 8. A lamp assembly as claimed in claim 7, said entrance opening being keyed to said base.9. A lamp assembly-for a luminaire having a housing with an interior and an exterior, said lamp assembly comprising:a socket supported by said housing; a lamp including a base, a light source extending axially from one side of said base, and a handle on the other side of said base; said socket including a passage extending axially through said socket to the interior of the housing; said passage being configured to receive said light source when said lamp is inserted into said socket to a mounted position wherein said base is received in said socket, said lamp extends beyond said socket into the interior of the housing, and said handle is directed toward the exterior of the housing; said socket including an entrance opening configured to receive said light source and said base, said passage being smaller than said entrance opening to block movement of said base and hold said base in said socket; said entrance opening being keyed to said base and said socket including a socket housing having a cavity permitting said base to rotate after entry into said into-said entrance opening. 10. A lamp assembly as claimed in claim 9, further comprising a lamp contact on said base and a socket contact mounted in said cavity, said lamp contact and said socket contact being engageable with one another upon said rotation of said base.11. A lamp assembly for a luminaire having a housing with an interior and an exterior, said lamp assembly comprising:a socket supported by said housing; a lamp including a base, a light source extending axially from one side of said base, and a handle on the other side of said base; said socket including a passage extending axially through said socket to the interior of the housing; said passage being configured to receive said light source when said lamp is inserted into said socket to a mounted position wherein said base is received in said socket, said lamp extends beyond said socket into the interior of the housing, and said handle is directed toward the exterior of the housing; said socket including an entrance opening configured to receive said light source and said base, said passage being smaller than said entrance opening to block movement of said base and hold said base in said socket; said entrance opening being keyed to said base; and said base having a pair of radially projecting wings and said entrance opening having radial extensions receiving said wings. 12. A lamp assembly as claimed in claim 11, said socket including a socket housing having a pair of cavities receiving said wings and permitting said base to rotate after axial movement of said wings through said extensions.13. A lamp assembly as claimed in claim 12, lamp contacts mounted on said wings and socket contacts mounted in said cavities, said lamp contacts being spaced from said socket contacts when said wings move axially through said extensions, and said lamp contacts engaging said socket contacts when said base rotates after axial movement of said wings through said extensions.14.
