I claim: 1. A display lighting system for illuminating a shelving structure comprising: a luminaire having a unitary lamp housing forming two linear lamp cavities along a central longitudinal axis between a pair of spaced opposed end caps, wherein a separate one of said end caps fully covers adjacent axial distal ends of said linear lamp cavities a pair of spaced arms each secured at a first end directly to said separate one of said end caps for positioning said display lighting system, wherein each of said spaced arms is positioned perpendicular to said central longitudinal axis of said linear lamp cavities each one of said end caps having a recess perpendicular to said central longitudinal axis and extending from only a portion of an outside edge of said end cap and across an outside surface of said end cap to a distance offset from said portion of said outside edge of said end cap whereby a remainder of said outside surface of said end cap remains laterally to the left and right of said recess, at least one of said recesses of said end caps having an aperture extending through from said recess to an inside surface of said end cap and substantially parallel to said central longitudinal axis of said linear lamp cavities for routing conductors therethrough and in electrical communication with a plurality of lamp holders, and said unitary lamp housing having said plurality of lamp holders secured between said pair of spaced opposed end caps for providing electrical power to a plurality of lamps, and for securing and positioning said lamps to illuminate from said two linear lamp cavities, one of said linear lamp cavities having at least one reflector secured thereto to reflect illumination from at least one of said plurality of lamps whereby one of said linear lamp cavities illuminates downwardly and inwardly towards a first target area and said other linear lamp cavity illuminates upwardly and inwardly towards a second target area, wherein said first target area is substantially exclusive from said second target area; and said recess of each one of said end caps directly receives said first end of said spaced arms to positively fix the mounting angle of said luminaire with respect to said first target area and said second target area since said remainder of said outside surface of each said end cap prevents rotation of said luminaire. 2. A display lighting system as claimed in claim 1 wherein said spaced arms are secured at a second end to an upright. 3. A display lighting system as claimed in claim 1 wherein said spaced arms include an aperture in said first end thereof, said aperture of said first end of said spaced arm being generally concentric with said aperture in said recess of said end cap. 4. A display lighting system as claimed in claim 1 further comprising a ballast mounted within an interior portion of said unitary lamp housing to provide starting electrical power to said lamps. 5. A display lighting system as claimed in claim 1 further comprising a transformer mounted within said unitary lamp housing to provide starting electrical power to said lamps. 6. A display lighting system as claimed in claim 1 wherein each of said end caps include a nipple disposed in said aperture of said recess of said end cap for routing said conductors from said luminaire to a similar adjacent luminaire, whereby said luminaire and said similar adjacent luminaire are axially aligned along said central longitudinal axis. 7. A display lighting system as claimed in claim 1 further comprising a plurality of fixed dividers between said lamp holders. 8. A first display lighting system capable of interconnecting to a similar second display lighting system for illuminating adjacent similar shelving structure comprising: a first luminaire having a pair of spaced opposed end caps, each of said opposing end caps having a slotted recess on an outside surface thereof with an aperture extending through said slotted recess to an inside surface of said end cap for routing wiring therethrough, and a unitary lamp housing secured at first and second ends thereof to said end caps, said unitary lamp housing forming a first linear lamp cavity and a second linear lamp cavity, each adjacent axial ends of said first linear lamp cavity and said second linear lamp cavity fully covered by said end caps each of said first linear lamp cavity and said second linear lamp cavity having at least one lamp to illuminate two lighting areas substantially exclusive of each other, one said lighting area directed in an upwardly and inwardly direction and said other lighting area directed in a downwardly and inwardly direction; and a pair of support arms having a first end that is directly received into said slotted recesses of said end caps positively fixing the mounting angle of said first luminaire, each said first end of said support arms having a second aperture concentrically aligned with said aperture of said slotted recess of said end cap, whereby said concentrically aligned said aperture and said second aperture allowing said wiring of said first luminaire to electrically interconnect to an axially adjacent similar second luminaire. 9. A display lighting system as claimed in claim 8 wherein said unitary lamp housing includes a fixed divider between said first linear lamp cavity and said second linear lamp cavity. 10. A display lighting system as claimed in claim 8 wherein one of said linear lamp cavities includes a reflector for at least one said lamp to reflect illumination from said lamp to said lighting area. 11. A display lighting system as claimed in claim 8 wherein said pair of support arms of said first luminaire are secured at a second end to an upright. 12. A display lighting system as claimed in claim 8 wherein said at least one lamp is incandescent. 13. A display lighting system as claimed in claim 8 wherein said at least one lamp is fluorescent. 14. A display lighting system for illuminating a shelving structure comprising: a luminaire having a pair of spaced opposed end caps and a unitary lamp housing forming two linear lamp cavities between said opposed end caps wherein said opposed end caps fully cover opposing adjacent axial ends of said two linear lamp cavities, each of said linear lamp cavities having a pair of lamp holders and a directional reflector, each of said end caps affixed directly to a support arm each having a first end and a second end, wherein each of said support arms is directly secured at said first end to a separate one of said end caps and said second end of said support arm is secured to said shelving structure, said first end of each of said support arms fixedly received into a substantially linear recess of an outer surface of said end cap that is substantially perpendicular to the axis of said two linear lamp cavities whereby preventing rotational or pivoting movement of said luminaire in relation to said support arms; and wherein one of said directional reflectors directs light downwardly and inwardly towards said shelving structure and said other directional reflector directs light upwardly and inwardly towards said shelving structure. 15. A display lighting system for illuminating towards a mounting structure comprising: a luminaire having a pair of spaced opposed end caps and an elongated unitary lamp housing, wherein said opposed end caps are positioned to fully cover said opposing distal ends of said elongated unitary lamp housing wherein a first end of a support arm directly affixes to one of said opposed end caps and a second end of said support arm affixes to said mounting structure, said support arm spacing said luminaire away from said mounting structure, whereby said first end of said support arm is directly and rigidly received in an elongated recess within said end cap that is substantially perpendicular to the longitudinal axis of said elongated unitary lamp housing preventing rotation and pivoting of said luminaire relative to said mounting structure; said elongated unitary lamp housing forming a first linear lamp cavity and a second linear lamp cavity, said first linear cavity having a first lamp and directs light downwardly and inwardly towards said mounting structure and said second linear lamp cavity having a second lamp and directs light upwardly and inwardly towards said mounting structure; and said first linear cavity and said second linear cavity is stationary relative to each other.
