The driver assembly (200) includes a housing (220) defining a cavity (234). The driver assembly (200) includes a driver circuit (210) disposed within the cavity (234). The driver circuit (210) can be configured to provide power to one or more light emitting diodes (116) of the lighting fixture (100). The driver assembly (200) can include a potting material (237) disposed within the cavity (234). The driver assembly (200) can include a base (260) attached to the housing (220) to enclose the driver circuit (210) and the potting material (237) within the cavity (234). ## Claims ### Claim 1 A driver assembly for a lighting fixture, the driver assembly defining a lateral direction (L), a transverse direction (T), and a vertical direction (V), the driver assembly comprising: a housing defining a cavity; a driver circuit disposed within the cavity, the driver circuit configured to provide power to one or more light emitting diodes of the lighting fixture; a potting material disposed within the cavity; and a base attached to the housing to enclose the driver circuit and the potting material within the cavity, wherein a bottom portion of the housing defines one or more indentations configured to accommodate one or more conductors associated with the driver circuit. ### Claim 2 (depends on 1) The driver assembly of claim 1, wherein the potting material comprises sand. ### Claim 3 (depends on 1) The driver assembly of claim 1, wherein the one or more indentations defined by the bottom portion of the housing includes: a first set of indentations; a second set of indentations spaced apart from the first set of indentations along the lateral direction (L); a third set of indentations spaced apart from the first set of indentations and the second set of indentations along the vertical direction (V); and a fourth set of indentations spaced apart from the first set of indentations and the second set indentations along the vertical direction (V), the fourth set of indentations further spaced apart from the third set of indentations along the lateral direction (L). ### Claim 4 (depends on 1) The driver assembly of claim 1, wherein the base defines one or more indentations configured to accommodate the one or more conductors associated with the driver circuit. ### Claim 5 (depends on 4) The driver assembly of claim 4, wherein the one or more indentations defined by the base include: a first set of indentations positioned adjacent a first side of the base; and a second set of indentations positioned adjacent a second side of the base, the second side spaced apart from the first side along the lateral direction (L). ### Claim 6 (depends on 1) The driver assembly of claim 1, wherein the base comprises: a first side defining a first recess configured to accommodate a first set of conductors associated with the driver circuit; and a second side spaced apart from the first side along the lateral direction (L), the second side defining a second recess configured to accommodate a second set of conductors associated with the driver circuit. ### Claim 7 (depends on 1) The driver assembly of claim 1, wherein a bottom portion of the housing defines: a first reservoir; and a second reservoir spaced apart from the first reservoir along the lateral direction (L). ### Claim 8 (depends on 7) The driver assembly of claim 7, wherein: at least a portion of the first reservoir is filled with the cement; and at least a portion of the second reservoir is filled with the cement. ### Claim 9 (depends on 8) The driver assembly of claim 8, wherein the bottom portion of the housing further defines: a first notch positioned adjacent the first reservoir; and a second notch positioned adjacent the second reservoir. ### Claim 10 (depends on 9) The driver assembly of claim 9, wherein: the cement flows into the first reservoir via the first notch; and the cement flows into the second reservoir via the second notch. ### Claim 11 (depends on 1) The driver assembly of claim 1, wherein: the housing includes a plurality of projections; and the base includes a plurality of tabs, each tab of the plurality of tabs (290, 292) engaging one projection of the plurality of projections to secure the base to the housing. ### Claim 12 (depends on 11) The driver assembly of claim 11, wherein the plurality of projections extend from a bottom portion of the housing. ### Claim 13 (depends on 11) The driver assembly of claim 11, wherein the plurality of tabs comprise: a first set of tabs extending from a front portion of the base, each tab of the first set of tabs configured to engage a projection of a first set of projections extending from the bottom portion of the housing; and a second set of tabs extending from a rear portion of the base, each tab in the second set of tabs configured to engage a projection of a second set of projections extend from the bottom portion of the housing. ### Claim 14 A driver assembly for a lighting fixture, the driver assembly defining a lateral direction (L), a transverse direction (T), and a vertical direction (V), the driver assembly comprising: a housing defining a cavity; a driver circuit disposed within the cavity, the driver circuit configured to provide power to one or more light emitting diodes of the lighting fixture; a potting material disposed within the cavity; and a base attached to the housing to enclose the driver circuit and the potting material within the cavity; wherein the base comprises: a first side defining a first recess configured to accommodate a first set of conductors associated with the driver circuit; and a second side spaced apart from the first side along the lateral direction (L), the second side defining a second recess configured to accommodate a second set of conductors associated with the driver circuit; and wherein both the first recess and the second recess are filled with a cement to seal the driver circuit and the potting material within the cavity.
