Abstract
An in-ground lighting apparatus has an enclosure for placement below the surface of the earth and a lamp is mounted for adjustable positioning in the housing. In the improvement, the lamp base and lamp are supported by two pivot-mounted brackets. The brackets are spaced from the lamp rim and provide lamp-grasping clearance between them for easy re-lamping. And the brackets permit the lamp to be adjusted to direct light anywhere within a cone-shaped 360.degree. envelope. The lamp is supported solely by its base. In a particular embodiment configured for use with HID lamps, the lamp and ballast assembly are constructed as an "integrated" unit which is easily lifted from the enclosure for service.
