This is a 4 section, 4000 watt maximum fixture, depending upon the optional bulbs chosen for use.
With a 1000 watt bulb, each section provides a beam of 20 footcandles 26 vertical feet and 30 horizontal feet in diameter from 20 feet away.
Die-cast aluminum and sheet steel construction. Baked black epoxy finish.
May be used with included floor trunnions, or hanging, with pipe clamps.
