a front cover having an overhang portion defining a recess portion and a front cover contact surface having a substantially flat contact portion facing in a rearward direction within the recess and at least one electronic component mounted on the front cover contact surface, the front cover connected to the first portion of the hinge; and a rear enclosure having a forward facing open front defined by a forward facing front edge, the rear enclosure connected to the second portion of the hinge and the front edge pressed against and forming a seal with the substantially flat contact portion. ### Claim 2 (depends on 1) The wall pack light fixture according to claim 1, wherein the hinge is offset to direct the front cover perpendicular to the front edge of the rear enclosure. ### Claim 3 (depends on 1) The wall pack light fixture according to claim 1, wherein the front edge of the rear enclosure comprises deformable material. ### Claim 4 (depends on 1) The wall pack light fixture according to claim 1, wherein the front edge of the rear enclosure comprises deformable material and the hinge is adapted so that the pressure of the front edge against the contact portion is substantially uniform. ### Claim 5 (depends on 1) The wall pack light fixture according to claim 1, wherein the front cover includes a light engine and the rear enclosure includes an enlarged portion and a battery backup within the enlarged portion, the battery backup electrically connected to the light engine. ### Claim 6 (depends on 5) The wall pack light fixture according to claim 5, wherein the rear enclosure includes an occupancy sensor that detects at least one of infrared light and motion coupled to the enlarged portion. ### Claim 7 (depends on 6) The wall pack light fixture according to claim 6, wherein the occupancy sensor has an adjustable sensitivity level. ### Claim 8 (depends on 5) The wall pack light fixture according to claim 5, wherein the light engine includes at least one of a light emitting diode (LED), a halogen light and an incandescent light. ### Claim 9 (depends on 1) The wall pack light fixture according to claim 1, wherein the front cover is made of die cast aluminum. ### Claim 10 (depends on 7) The wall pack light fixture according to claim 7, wherein the front cover is coated with a polyester powder. ### Claim 11 (depends on 1) The wall pack light fixture according to claim 1, wherein the front cover includes a finned section. ### Claim 12 A wall pack light fixture, comprising: an offset hinge having a first portion and a second portion pivotably coupled to the first portion; a front cover having a front cover contact surface having a substantially flat contact portion circumscribing an inner region facing in a rearward direction and at least one electronic component mounted on the front cover contact surface within the inner region, the front cover connected to the first portion of the offset hinge; and a rear enclosure having a forward facing open front defined by a forward facing front edge having compressible material thereon, the rear enclosure connected to the second portion of the hinge and the front edge pressed against and forming a seal with the substantially flat contact portion, the hinge adapted to direct the front cover in a perpendicular direction into the rear enclosure, wherein the pressure at the seal is substantially uniform. ### Claim 13 (depends on 12) The wall pack light fixture according to claim 12, wherein the front cover includes a light engine, the rear enclosure includes an occupancy sensor and the rear enclosure includes an enlarged portion and a battery backup within the enlarged portion, the battery backup electrically connected to the light engine. ### Claim 14 (depends on 13) The wall pack light fixture according to claim 13, wherein the occupancy sensor detects at least one of infrared light and motion. ### Claim 15 (depends on 13) The wall pack light fixture according to claim 13, wherein the occupancy sensor has an adjustable sensitivity level. ### Claim 16 (depends on 13) The wall pack light fixture according to claim 13, wherein the light engine includes at least one of a light emitting diode (LED), a halogen light and an incandescent light. ### Claim 17 (depends on 13) The wall pack light fixture according to claim 13, wherein the front cover is made of die cast aluminum. ### Claim 18 (depends on 17) The wall pack light fixture according to claim 17, wherein the front cover is coated with a polyester powder. ### Claim 19 (depends on 12) The wall pack light fixture according to claim 12, wherein the front cover includes a finned section. ### Claim 20 (depends on 12) The wall pack light fixture according to claim 12, wherein the front cover includes a light engine, wherein the light engine includes at least one of a light emitting diode (LED), a halogen light and an incandescent light; and the rear enclosure includes an occupancy sensor and a battery backup, wherein the battery backup is electrically connected to the light engine and configured to provide electrical energy to the light engine in response to detection of an occupant by the occupancy sensor.
