A lighting assembly includes a lighting unit having a housing defining an internal cavity and an opening. A light source is assembled within the internal cavity of the housing. An electrical wire is electrically connected to the light source at a first end and is configured to be contained at least in part within the housing. The opening is configured to permit withdrawal of a user selected amount of the electrical wire from within the internal cavity and/or to permit a user selected amount of the electrical wire to be inserted into the internal cavity.

We claim: 1. A lighting assembly comprising at least one lighting unit, each lighting unit comprising: a housing comprising a base portion and an outer portion, the housing being configured to define an internal cavity and a gap around an outer perimeter of the housing between the base portion and the outer portion; a circuit board disposed within the housing; at least one light emitting diode carried by the circuit board; and an electrical wire having a first end electrically connected to the circuit board, the electrical wire being configured to be wound around a hub disposed radially inward of the gap; wherein the gap is configured to permit withdrawal of a user selected amount of a wound portion of the electrical wire from within the internal cavity; and wherein the at least one lighting unit further comprises a mounting fastener for securing the housing of the at least one lighting unit to an external structure, the housing being rotatable about the mounting fastener to selectively adjust the orientation of the at least one lighting unit with respect to the external structure. 2. The lighting assembly of claim 1, further comprising a means for applying a retaining force to retain the wound portion of the electrical wire within the internal cavity, such that a user applied pulling force on the electrical wire overcomes the retaining force to withdraw the user selected amount of the wound portion of the electrical wire. 3. The lighting assembly of claim 2, wherein the means for applying the retaining force comprises at least a portion of the gap sized to inhibit movement of the electrical wire through the gap. 4. The lighting assembly of claim 1, further comprising a substrate disposed within the housing, the circuit board being thermally coupled to the substrate. 5. The lighting assembly of claim 4, wherein the substrate further comprises at least one peripheral projection configured to be received in a corresponding peripheral opening of the housing, such that the at least one peripheral projection is exposed to an external environment. 6. The lighting assembly of claim 4, further comprising an end flange extending radially from the hub opposite the substrate, wherein the substrate, hub and end flange form a spool member for retaining the wound portion of the electrical wire. 7. The lighting assembly of claim 1, further comprising a voltage converter electrically connected to a second end of the electrical wire for supplying power to the at least one light emitting diode. 8. The lighting assembly of claim 1, further comprising a second electrical wire having a first end electrically connected to the circuit board, the second electrical wire extending through an opening in the housing for connecting with a second lighting unit. 9. The lighting assembly of claim 1, wherein the gap extends around the entire outer perimeter of the housing. 10. The lighting assembly of claim 1, further comprising an electrical plug electrically connected to a second end of the electrical wire of the lighting unit for supplying power to the at least one LED. 11. The lighting assembly of claim 1, wherein the at least one lighting unit comprises first and second lighting units, wherein the electrical wire of the second lighting unit is electrically connected at a second end to the first lighting unit for communicating electricity from the first lighting unit to the at least one LED of the second lighting unit. 12. The lighting assembly of claim 11, wherein a second end of the electrical wire of the second lighting unit extends into the first lighting unit housing through an opening in the base member of the first lighting unit. 13. The lighting assembly of claim 1, further comprising a junction box including a housing carrying a driver circuit board, a plurality of lighting unit output connectors, a junction box inlet connector for receiving a supply voltage from an associated power supply, and a junction box output connector for transmitting the supply voltage to an associated module of a modular lighting system, wherein a second end of the electrical wire of each lighting unit is configured to be connected to one of the plurality of lighting unit output connectors. 14. The LED lighting arrangement of claim 1, wherein the mounting fastener comprises a pan screw. 15. A lighting assembly comprising at least one lighting unit, each lighting unit comprising: a housing comprising a base portion and an outer portion, the housing being configured to define an internal cavity and a gap around an outer perimeter of the housing between the base portion and the outer portion; a circuit board disposed within the housing; at least one light emitting diode carried by the circuit board; an electrical wire having a first end electrically connected to the circuit board, the electrical wire being configured to be wound around a hub disposed radially inward of the gap; and a substrate disposed within the housing, the circuit board being thermally coupled to the substrate; wherein the gap is configured to permit withdrawal of a user selected amount of a wound portion of the electrical wire from within the internal cavity; and wherein the substrate further comprises at least one peripheral projection configured to be received in a corresponding peripheral opening of the housing, such that the at least one peripheral projection is exposed to an external environment. 16. A lighting assembly comprising at least one lighting unit, each lighting unit comprising: a housing comprising a base portion and an outer portion, the housing being configured to define an internal cavity and a gap around an outer perimeter of the housing between the base portion and the outer portion; a circuit board disposed within the housing; at least one light emitting diode carried by the circuit board; an electrical wire having a first end electrically connected to the circuit board, the electrical wire being configured to be wound around a hub disposed radially inward of the gap; and a substrate disposed within the housing, the circuit board being thermally coupled to the substrate; wherein the gap is configured to permit withdrawal of a user selected amount of a wound portion of the electrical wire from within the internal cavity; and wherein the lighting assembly further comprises an end flange extending radially from the hub opposite the substrate, wherein the substrate, hub and end flange form a spool member for retaining the wound portion of the electrical wire. 17. The lighting assembly of claim 16, further comprising a means for applying a retaining force to retain the wound portion of the electrical wire within the internal cavity, such that a user applied pulling force on the electrical wire overcomes the retaining force to withdraw the user selected amount of the wound portion of the electrical wire. 18. The lighting assembly of claim 17, wherein the means for applying the retaining force comprises at least a portion of the gap sized to inhibit movement of the electrical wire through the gap. 19.
