What is claimed is: 1. A light generating assembly for a projector, said light generating assembly comprising: a reflector assembly comprising positive and negative electrical contacts disposed on said reflector assembly; and a replaceable lamp with a supporting lamp header, said lamp header comprising: a base member and an annular lamp engaging protrusion extending from a first surface of said base member; at least two positive and two negative source connections disposed on opposing portions of said base member such that said lamp can be positioned within said reflector assembly in either a first orientation or a second orientation, said second orientation being rotated 180 degrees from said first orientation with respect to said reflector assembly, wherein in each orientation one of said positive source connections and one of said negative source connections is electrically coupled, respectively, to said positive contact and said negative contact of said reflector assembly; a positive and a negative lamp connection coupled to said annular lamp engaging protrusion; and an electrical interconnect coupling each of said positive source connections to said positive lamp connection and coupling each of said negative source connections to said negative lamp connection. 2. The assembly of claim 1, wherein said electrical interconnects are contained within said base member and said annular lamp engaging protrusion. 3. The assembly of claim 1, wherein said header is configured to be removably coupled to a reflector assembly. 4. The assembly of claim 1, wherein said header comprises a ceramic material. 5. The assembly of claim 1, further comprising an indication of a preferred orientation of a lamp assembly with respect to said reflector assembly being marked on said header. 6. The assembly of claim 1, wherein said contacts are fixed in position with respect to said reflector assembly, but make contact with at least some of said positive and negative source connections when said lamp header is installed, irrespective of said lamp orientation, to provide power to said lamp. 7. The assembly of claim 1, wherein said annular lamp engaging protrusion defines a lamp engaging cavity. 8. The assembly of claim 7, wherein said lamp connections are disposed on a lip of said annular lamp engaging protrusion and disposed within said lamp engaging cavity. 9. A replaceable lamp header for positioning a lamp within a reflector assembly, comprising: a base member and an annular lamp engaging protrusion extending from a first surface of said base member; at least two positive and negative source connections disposed on opposing portions of said base member; a positive and a negative lamp connection coupled to said annular lamp engaging protrusion; an electrical interconnect coupling each of said positive source connections to said positive lamp connection and coupling each of said negative source connections to said negative lamp connection; and an active device coupled to said header. 10. The header of claim 9, wherein said active device is coupled to said base portion of said header. 11. The header of claim 9, further comprising a plurality of memory contact pads disposed on said base member; wherein said plurality of memory contact pads are coupled to said active device and are configured to facilitate a rotation of said base member. 12. The header of claim 9, wherein said active device comprises a memory device. 13. The header of claim 12, wherein said memory device contains a firmware update for a control assembly of a projection system. 14. A replaceable lamp header for positioning a lamp within a reflector assembly, comprising: a base member and an annular lamp engaging protrusion extending from a first surface of said base member; at least two positive and two negative source connections disposed on opposing portions of said base member; a positive and a negative lamp connection coupled to said annular lamp engaging protrusion; an electrical interconnect coupling each of said positive source connections to said positive lamp connection and coupling each of said negative source connections to said negative lamp connection; and two positive and two negative source connections with a positive and negative source connection being disposed on said first surface on both sides of said annular lamp engaging protrusion. 15. The header of claim 14, wherein: said base member has a rectangular shape; said two negative source connections are disposed on diagonally opposing portions of said base member; and said two positive source connections are disposed on diagonally opposing portions of said base member. 16. A light generating assembly for a projector, said light generating assembly comprising: a reflector assembly comprising positive and negative electrical contacts disposed on said reflector assembly; and a replaceable lamp with a supporting lamp header, said lamp header comprising: a base member and an annular lamp engaging member extending from a first surface of said base member; positive and negative source connections disposed on opposing portions of said first surface of said base member such tat said lamp can be positioned within said reflector assembly in either a first orientation or a second orientation, said second orientation being rotated 180 degrees from said first orientation with respect to said reflector assembly, wherein in either orientation a said positive source connection and a said negative source connection are electrically coupled, respectively, to said positive contact and said negative contact of said reflector assembly, wherein said positive and negative source connections align with said contacts of said reflector assembly when said lamp is in either said first or second orientation so as to allow said lamp header to make electrical connections with said contacts of said reflector assembly in either said first or second orientation; a positive and a negative lamp connection coupled to said annular lamp engaging member; and an electrical interconnect coupling said positive source connection to said positive lamp connection and coupling said negative source connection to said negative lamp connection. 17. The assembly of claim 16, wherein said contacts are fixed in position with respect to said reflector assembly, but make contact with at least some of said positive and negative source connections when said lamp header is installed, irrespective of said lamp orientation, to provide power to said lamp.
