Lighting fixtures having mounting structure openings and coverings

A lighting fixture comprising:

• a housing defining space for holding an electrical ballast for distributing power to one or more light sources, wherein the electrical ballast is configured to limit current applied to the one or more light sources;
• a mounting structure attached to the housing and configured to at least partially enclose the space for containing the electrical ballast, the mounting structure defining an opening for accessing the electrical ballast, wherein the mounting structure is configured to attach to the one or more light sources;
• a covering attached to the mounting structure and arranged to cover the opening when attached, wherein the covering comprises a hinge at an end, the hinge being connected to and operable with the mounting structure to permit the covering to pivot at the hinge between an open position and a close position, wherein in the closed position, the covering covers the opening, and wherein in the open position, the covering is at least partially distanced from the opening to permit access through the opening into the space defined by the housing;
• an attachment mechanism configured to attach the covering to the mounting structure in the closed position;
• an electrical quick-disconnect coupler configured to electrical connect and disconnect the electrical ballast from the at least one electrical wire;
• and
• a screw assembly that attaches the electrical ballast to the covering.
