ABSTRACT:
A variable beam floodlight fixture is provided for simply and quickly changing the width of the beam by means of a single operating lever which controls ganged, multiple, pivoted reflector sections. Pivoted reflector sections are provided on opposite sides of a fixed central reflector, and the multiple sections on each side simultaneously pivot in different amounts under control of the operating lever to provide a uniform beam at the various angles available from the narrowest beam to the widest beam attainable from the fixture.
