According to a one embodiment of the instant invention an adjustable downlight assembly comprises a collar, a yoke adjustable through an arcuate distance, the yoke pivotally connected to the collar, and a worm gear drive assembly operably engaging the yoke and the collar for pivoting the yolk about a horizontal axis. The worm gear drive assembly comprises a worm and a gear. The worm gear drive assembly is adjustable by rotation of the worm. The adjustable downlight assembly further comprises a biasing member fastened to a casting, the casting extending from an inner surface of the collar. The worm gear drive assembly inhibits unintentional movement of the yoke after adjustment is completed.
