Abstract
A ballast housing having a rolled edge lead wire exit for providing protection and strain relief to lead wires extending out from the housing. Grommets are not required in order to provide protection and strain relief to lead wires exiting the housing. The housing includes a lead wire opening having rolled upper and lower edges. The housing includes a lid including the rolled upper edge and a can including the rolled lower edge. The rolled upper edge is vertically aligned with the rolled lower edge but horizontally misaligned with the rolled lower edge. As a result, the rolled upper edge is positioned away from the rolled lower edge a distance that is horizontally shorter than the diameter of the lead wire. Additionally, the lead wire opening has a vertical diameter that is shorter than the diameter of the lead wire.
