The fixture of claim 14, wherein each of the plurality of panels are set at a first angle along a vertical plane bisecting the support plate and a second angle along a lateral plane extending from a side of the support plate to a front of the support plate so as to produce any of IESNA-specified Type I, Type II, Type III and Type IV roadway illumination patterns. 18. The fixture of claim 14, further comprising: a hinge mount assembly attaching each panel to the support plate, the hinge mount assembly enabling a given panel to be rotated in at least two dimensions. 19. The fixture of claim 14, wherein the panels with LED arrays thereon are configured to provide a total light output of at least 8000 lumens. 20. The fixture of claim 14, further comprising: a power supply attached to the support plate for driving the LED arrays. 21. A LED lighting fixture, comprising: a support plate, a first pair of front panels, a second pair of rear panels, each of the front and rear panels connected to the support plate and having an array of LEDs mounted to a planar surface thereof, one or more of the front and rear panels individually adjustable to create a desired illumination pattern, and a power supply attached to the support plate for driving the LED arrays. 22. The fixture of claim 21, wherein the LED arrays on the front panels are fitted with secondary optics and the LED arrays on the rear panels have no optics. 23. The fixture of claim 21, wherein each of the front and rear panels are set at a first angle along a vertical plane bisecting the support plate and a second angle along a lateral plane extending from a side of the support plate to a front of the support plate so as to produce any of IESNA-specified Type I, Type II, Type III and Type IV roadway illumination patterns. 24. The fixture of claim 21, further comprising: a hinge mount assembly attaching each panel to the support plate, the hinge mount assembly enabling a given front and rear panel to be rotated in at least two dimensions. 25. The fixture of claim 21, wherein the front and rear panels with LED arrays thereon are configured to provide a total light output of at least 8000 lumens. 26. A LED lighting fixture, comprising: a support plate, a first plurality of front panels, a second plurality of rear panels, each of the front and rear panels separately connected to the support plate and having an array of LEDs mounted to a planar surface thereof, and each of the front and rear panels are separately set at a first angle for the respective panel along a vertical plane bisecting the support plate and a second angle for the respective panel along a lateral plane extending from a side of the support plate to a front of the support plate so as to produce at least one of IESNA-specified Type I, Type II, Type III and Type IV roadway illumination patterns. 27.
