A light fixture includes a lamp engine, an electronic module connected to the lamp engine and a photometric module mounted to the light engine. The electronic module is connected to the light source and an associated power source for providing power to the light source. The photometric module mounts to the light engine and creates a beam pattern that illuminates a substantial portion of an entire associated subject area. The method of illuminating a large area includes determining a subject area to be illuminated by a plurality of light sources and determining a desired lighting criteria for the subject area. A first light source is provided and light emitted from the first light source is directed to illuminate the subject area. Additional light sources are provided and directed to provide additional light to illuminate the same portion of the subject area until the desired lighting criteria are met.

What is claimed is: 1. A method of providing redundancy when illuminating a subject area with a plurality of light sources where the subject area has a desired lighting criteria, the method comprising the steps of: providing a first light source having a first photometric module; directing light emitted from the first light source to illuminate the subject area; providing an additional light source having an additional photometric module; directing light emitted from the additional light source to illuminate the subject area; and repeating the previous two steps until the lighting criteria are met; wherein for each of the directing steps the subject area comprises an area from the group consisting of substantially the entirety of a football field, a baseball field, a softball field, a soccer field, a recreation field, an arena floor, a tennis court, an exercise floor, a gymnasium floor, a parking lot, and combinations thereof. 2. The method of claim 1, wherein for each of the providing steps the additional photometric module is substantially identical to the first photometric module. 3. The method of claim 1, further comprising: aiming the first light source toward a target point; and aiming each additional light source substantially toward a point offset from the target point by a dimension that corresponds to center to center spacing between the additional light source and the first light source. 4. The method of claim 3, further comprising alternating which light source illuminates the subject area. 5. The method of claim 1, wherein for the providing a first light source step, the first light source mounts to a first light pole, and wherein for the providing an additional light source step, the additional light source mounts to an additional light pole, further comprising the steps of: aiming the first light source toward a target point; and aiming the additional light source toward the target point. 6. The method of claim 1, wherein the providing an additional light source step comprises the additional light source having a photometric module that creates a photometric beam that is the mirror image of a photometric beam created by the first photometric module. 7. A method of providing illumination of an associated subject area, the method comprising the steps of: providing a housing fixture; a lamp disposed in the fixture housing; providing a first reflector shaped and positioned with respect to the lamp such that the reflector collects light emitted from the lamp to create a converging beam with limited angular mixing at a surface that is located a predetermined distance from the lamp; providing a photometric module connected to the housing and including a second reflector, wherein the second reflector is shaped and positioned with respect to the first reflector such that the photometric module generates a photometric beam shape that substantially uniformly illuminates a full width of the associated subject area, wherein the associated subject area comprises an area from the group consisting of a football field, a soccer field, a recreation field, an arena floor, a tennis court and a gymnasium floor. 8. The assembly of claim 7, wherein the lamp comprises an arc tube axis that is at least within 15 degrees of vertical. 9. The assembly of claim 8, wherein the first reflector comprises a concave upward reflector coaxial with the arc tube axis. 10. The assembly of claim 7, wherein the second reflector is shaped and positioned with respect to the first reflector to generate a photometric beam shape that uniformly illuminates the full length of the subject area.
