ALL YOU DO IS STRIKE THE ARC
The positive and negative carbons are advanced by separate motors, the speeds of which are governed by the Bi-metal Lightronic Tube. Once the arc has been struck, the crater position and gap length are maintained automatically, and without constant attention by the projectionist.
With the new presentation techniques complicating his job, the projectionist is particularly appreciative of this simplified control. Furthermore, he is quick to see the advantages of the unitized component design which affords such wide versatility in these lamps. He can, in a matter of moments and right in his projection room, effect the simple changes necessary to attain the correct light requirement for any of the various techniques. It is even possible for him to get the light requirements of two different types of techniques on the same program.
TRUE VERSATILITY
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.
SIMPLIFIED CONTROL
r
Only one control is required for selecting any amperage within the range of a particular mode of operation.
THE MOST POWERFUL LAMPS
Burning 10 mm "Hitex" carbons at 135 amperes, or I mm regular carbons 3t 120 amperes, impartial foot candle meter tests prove the Strong Super "135" the most powerful projection arc lamp, and you can't argue with a light meter.
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 n 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.
Strong has also designed new rectifiers with a range of from 90 to 135 amperes to fill the power requirements of all the systems of screen presentation.

As the only lamps produced complete within one factory, Strong lamps can be screen-engineered for maximum efficiencies. That’s why more dealers sell and more theatres buy Strong-made projection arc lamps than any other make.
