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.

Abstract
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.
