Abstract
The invention provides a floodlight in which the lamp axis is offset from the axis of a reflector. In the preferred embodiment an arc lamp is oriented vertically when the reflector axis is oriented at an oblique downward angle. The reflector includes a back reflector having a parabolic reflecting surface and a front reflector having at least one ellipsoidal reflecting surface disposed symmetrically about the reflector axis. In a preferred embodiment the front reflector is hinged to the back reflector and can be pivoted away from the back reflector to expose the lamp to facilitate cleaning and maintenance.
