Correct Screen Lighting for One, Two or More Different Techniques
ON THE SAME PROGRAM!
f >
The unitized component design of
PROJECTION ARC LAMPS
permits the projectionist, in a matter of moments, to effect the simple changes necessary to attain the correct light requirement for any of the various techniques. A choice of four different carbon trims can be burned in a total of seven separate manners to attain any desired degree of cost of operation, screen illumination, or burning time. Only one control is required for selecting any amperage within the range of a particular mode of operation.
PERFECT LIGHT MAINTAINED WITHOUT MANUAL ADJUSTMENTS!
Strong's Exclusive Lightronic crater-positioning system automatically maintains the correct arc gap length and the position of the positive arc crater at the EXACT focal point of the reflector. No manual adjustments are necessary. A perfect light is maintained at the screen ... a powerful light, evenly distributed, of constant intensity, and unchanging color value.
Burning 10 mm "Hitex" carbons at 135 amperes, or 1 1 mm regular carbons at 120 amperes, impartial foot-candle-meter tests prove the Strong "Super 135"
THE MOST POWERFUL OF ALL PROJECTION LAMPS!
The Infra-Ban Beam Cooler Unit diverts the heat rays away from the aperture, making possible a tremendous increase in usable light without a corresponding increase in heat at the aperture.
A stream of air directed just above the arc stabilizes its burning and prevents the deposit of soot on the reflector.
