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.
