A fluorescent lamp fixture includes a housing (10), an elongate reflector (30) on one side of the housing (10) with two sets of fluorescent lamp sockets (24, 26) extending from the reflector (30) and a refracting lens (52) extending over the reflector (30) and fluorescent lamp sockets (24, 26). A second reflector (44) is positioned to extend across and face the first reflector (30) with two fluorescent lamps (28) mounted between the two reflectors (30, 44). The second reflector (44) includes reflective longitudinal surfaces (46, 48) on either side of the reflector (44) to reflect light from the adjacent fluorescent lamps (28) laterally thereof. The principal reflector (30) is a diffuse reflector while the second reflector (44) is a specular reflector. The specular reflector (44) is mounted to the refracting lens (52).

What is claimed is: 1. A fluorescent lamp fixture comprising a fixture housing; an elongate first reflector to one side of the housing; an elongate second reflector displaced from and facing the first reflector, the first reflector extending laterally in both directions beyond the second reflector; at least one set of fluorescent lamp sockets extending outwardly from the first reflector toward the second reflector to define a fluorescent lamp mounting location directly between the first reflector and the second reflector and longitudinally aligned with the first reflector and the second reflector, the second reflector extending laterally outwardly of the fluorescent lamp mounting location and having reflective longitudinal surfaces on either side to reflect light coming from the adjacent fluorescent lamp mounting location laterally of the second reflector directly out of the fixture housing, wherein the at least one set of sockets are positioned such that light is reflected downwardly and upwardly from the fixture by the first and second reflectors laterally through more than 180° degrees. 2. The fixture of claim 1, there being two sets of fluorescent lamp sockets defining the fluorescent lamp mounting location and the second reflector extending fully across and laterally outwardly of the two fluorescent lamp mounting location. 3. The fixture of claim 1, the first reflector being a diffuse reflector. 4. The fixture of claim 1, the reflective longitudinal surfaces being specular reflectors. 5. The fixture of claim 1 further comprising a refracting lens extending from the housing around the first reflector, the fluorescent lamp mounting location and the second reflector. 6. The fixture of claim 5, the refracting lens being a diffuser lens. 7. The fixture of claim 5, the second reflector being mounted to the refracting lens. 8. The fixture of claim 5 further comprising overcenter latches mounted on the fixture housing and including engagements depending there from to engage the refracting lens, at least some of the engagements having springs biasing the engagements away from the refracting lens. 9. The fixture of claim 1, the mounting location lying in a plane, the longitudinal reflective surfaces being at 43° to the plane of the mounting location. 10. The fixture of claim 1, the second reflector further having an elongate flat section between the reflective longitudinal surfaces. 11. The fixture of claim 1, the lateral cross section of the first reflector having two sections being concave toward the fluorescent lamp mounting-location. 12. A fluorescent lamp fixture comprising a fixture housing; an elongate diffuse reflector to one side of the housing; an elongate specular reflector displaced from and facing the diffuse reflector, the diffuse reflector extending laterally in both directions beyond the specular reflector; at least two set of fluorescent lamp sockets extending outwardly of the diffuse reflector toward the specular reflector to define at least two fluorescent lamp mounting locations directly between the diffuse reflector and the specular reflector and longitudinally aligned with the diffuse reflector and the specular reflector, the specular reflector extending fully across the at least two mounting locations and laterally outwardly of the fluorescent lamp mounting locations and having reflective longitudinal surfaces on either side of the specular reflector to reflect light coming from the adjacent fluorescent lamp mounting location laterally of the specular reflector directly out of the fixture housing, wherein the at least one two set of sockets are positioned such that light is reflected downwardly and upwardly from the fixture by the diffuse and specular reflectors laterally through more than 180° degrees. 13. The fixture of claim 12 further comprising a refracting diffuser lens extending from the housing around the first reflector, the fluorescent lamp mounting location and the second reflector. 14. The fixture of claim 13, the specular reflector being mounted to the refracting lens. 15. The fixture of claim 12, the mounting location lying in a plane, the longitudinal reflective surfaces being at 43° to the plane of the mounting location. 16. The fixture of claim 12, the lateral cross section of the diffuser reflector having two sections being concave toward the fluorescent lamp mounting location. 17. The fixture of claim 12, there being two sets of fluorescent lamp sockets defining the fluorescent lamp mounting locations. 18. A fluorescent lamp fixture comprising a fixture housing; an elongate first reflector to one side of the housing; an elongate second reflector displaced from and facing the first reflector, the first reflector extending laterally in both directions beyond the second reflector; at least two set of fluorescent lamp sockets spaced apart extending outwardly from the first reflector toward the second reflector to define at least two fluorescent lamp mounting locations directly between the first reflector and the second reflector and longitudinally aligned with the first reflector and the second reflector; wherein the second reflector extends laterally and outwardly to fully overlap the at least two mounting locations and having reflective longitudinal surfaces on either side to reflect light coming from the fluorescent lamp mounting location laterally of the second reflector, wherein the at least one set of sockets are positioned such that light is reflected downwardly and upwardly from the fixture by the first and second reflectors laterally through more than 180° degrees; and wherein the lateral cross section of the first reflector comprises two concave sections, the concave sections each further defined by substantially planar outermost, middle, and inner elements disposed at different angles relative to plane of the fluorescent lamp mounting location. 19. The fixture of claim 18, the second reflector further comprising an elongate flat section between the reflective longitudinal surfaces. 20. The fixture of claim 19, the longitudinal reflective surfaces being at an angled relation relative to the plane of the fluorescent lamp mounting location. 21. The fixture of claim 18, wherein the angles for the outermost and middle elements are 21° and 8°, respectively, and for the inner element, 14° in the opposite rotation.
