COMPLETE riEXlBlLITT
The exacting higb standards of screen lllnmination required for good presentation of the new projection techniques have been realized with the development of Strong's Lightronic crater-positioning system.
A choice of four different carbon Wms can he 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 p^icnlar

mode of operation.
It automatically maintains the conect arc gap length and the position of the positive arc crater at the EXACT focal point of the reflector.

THE MOST POWEBFUL LAMPS
Burning 10 mm "Hitex" carbons at 135 amperes, or II mm regular carbons at 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.
INFBA-BAN BEAM COOLEB UNIT
The projectionist is not chained to the lamp in order to keep a perfect light on the screen... a powerful light, evenly distributed, of constant intensity, and unchanging color value.
COBBECT LIGHT BEQUIBEMENTS FOB TWO DIFFEBENT TECHNIQUES POSSIBLE ON THE SAME PBOGBAM!
The unitized component desip affords wide versatility in these lamps. The projectionist can, in a matter of moments, effect the simple changes necessary to attain the correct light requirement for any of the tmrious technipes.
Diverts the heat rays away from the aperture, making possible a tremendous increase in usable light without a conesponding 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 reDector.
PEOPLE GO MOBE OFTEN TO THE THEATBE WHICH HAS GOOD PBOJECTION
As the only lamps produced jomplete within one factory, Strong lamps can be screen -engineered for maximum efficiencies. That's why more dealers sell and more theatres buy Strong-made projec¬ tion arc lamps than any other make.

Strong has also designed netv rectifiers with a range oj from 90 to 1.^5 amperes to fill the power recfuirements of all the systems of screen presentation.
