Abstract: An in-grade light fixture is provided with a corrugated housing design. The corrugated housing design enhances structural integrity and the flow of air within the light fixture to facilitate cooling. The light fixture includes an annular door with slots aligned with the corrugations to facilitate the influx of cool air into the housing and the exhaust of hot air from the housing. The light fixture includes a hot-aiming system that allows a tilt optic to be rotated via magnetic force within the light fixture using an external instrument, such as magnetic wand. The beam direction can be rotated using this hot-aiming system without opening the light fixture.

Abstract: A knuckle assembly for mounting an electrical device includes a rotatable knuckle mount, an articulated knuckle and an electrical device mount. Two knuckle elements forming the articulated knuckle each include an open cavity, which together form a closed cavity. One of the knuckle elements is pivotally attached to the rotatable knuckle mount and the other includes the electrical device mount. A grommet is positioned in the closed cavity; and a fastener engages the knuckle elements and extends through the grommet. The grommet includes spherical or spheroidal segments complementary to the inner surfaces of the closed cavity and in interfering fit when assembled. The grommet is in non-rotational engagement with one of the knuckle elements. Wires extend through the grommet adjacent a central through hole. A fastener extending through the central through hole draws the knuckle elements together to fix the grommet and seal the assembly.
