1. A luminaire comprising a rectangular waveguide, said waveguide including four edges and opposed planar surfaces and being configured for installation with said opposed planar surfaces oriented horizontally, a light module directing light into only one of said edges, each of said planar surfaces emitting light, wherein said light is emitted selectively in a greater amount upwardly or downwardly. 2. The luminaire of claim 1, wherein said waveguide has a thickness of less than 50 mm between opposed planar surfaces. 3. The luminaire of claim 1 wherein said light module includes a plurality of light emitting diodes (LEDs). 4. The luminaire of claim 1 wherein said rectangle is a square. 5. The luminaire of claim 1 wherein light is emitted substantially from only one planar surface. 6. The luminaire of claim 2 wherein the ratio of surface area of one planar surface to waveguide thickness is at least 5,000:1. 7. The luminaire of claim 1 including a mounting structure associated with the edge including said light module. 8. The luminaire of claim 7 wherein an edge opposed to said edge including said mounting structure is free floating in a mounted condition. 9. The luminaire of claim 7 wherein said mounting structure and said light module comprise an integral body. 10. The luminaire of claim 1 wherein light exits said planar surface diffusely. 11. The luminaire of claim 1 wherein at least one edge includes a reflector. 12. The luminaire of claim 4 wherein a first planar surface emits more light than the opposed planar surface. 13. A method for illuminating an area comprising providing a plurality of luminaire, each luminaire comprising a rectangular waveguide including four edges and opposed planar surfaces, each waveguide including a light module directing light into only one of the edges, each waveguide having total internal reflectance which distributes said light throughout the waveguide and a selected emission of light from one or both of said planar surfaces, and arranging at least a first of said luminaires in a vertical orientation and a second of said luminaires in a horizontal orientation. 14. The method of claim 13 wherein said first luminaire is mounted to a ceiling and said second luminaire is mounted to a wall. 15. The method of claim 13 wherein each luminaire has substantially the same length, width and thickness. 16. A luminaire comprising a rectangular waveguide, said waveguide including four edges and opposed planar surfaces, a light module directing light into only one of said edges, wherein light is directed to exit said waveguide from at least one planar surface within a cone angle of less than about 45°. 17. A luminaire comprising a rectangular waveguide, said waveguide including four edges and opposed planar surfaces, a light module directing light into only one of said edges, at least one of said planar surfaces emitting light, wherein said light is emitted selectively in a greater amount upwardly or downwardly and wherein light is emitted from at least one of said edges. 18. The method of claim 13 including a plurality of vertical luminaires and a plurality of horizontal luminaires. 19. The method of claim 16 wherein light is directed to exit said waveguide from each opposed planar surface within a cone angle of less than about 45°. 20. The luminaire of claim 1 wherein said light is emitted in a greater amount downwardly.
