A ruggedly constructed long throw follow spot, the Explorer produces a very narrow hard of soft edge beam which varies from 5? to 7?. At a distance of 150 feet, adjusted in spot focus, the beam is 15' in diameter with a peak measurement of 333 footcandles. The Explorer is designed for use with the OSRAM 1200 watt metal halide lamp for optimal performance. The ball bearing slide assembly assures easy operation of focusing from spot to flood and separate fine focus control assures a clean, hylation free beam edge. The lamphouse is supported by a heavy-duty screw-feed lift that allows the operator to make necessary adjustments for comfort of operation. The luminaire is used in any application where manual control of a lighting beam is required to follow a performer and to vary beam size, quality and color.
