ABSTRACT:
A luminaire of an HID lamp includes a wiring box pivotally mounted on a yoke and a lamp and reflector mounted on the box. The lamp is mounted with its axis perpendicular to a normally horizontal surface of the box. The reflector is mostly formed as surfaces of revolution but has a flat mounting surface offset from the reflector axis at a predetermined angle, preferably about 36.degree. for use with a lamp having a .+-.15.degree. operating angle deviation from vertical. Thus, the aiming angle can be between 21.degree. and 51.degree. from vertical.
