You Can
Use a
Mazda Projection Easily Adapted to Your Movie Machine
"We have had many years of experience in the electrical field, and in presenting the PROJECT-A-LITE to the Motion Picture industry are able to put the result of that experience into the product. Our alternating current regulating transformer reduces line current to 30 volts and regulates it at 30 amperes, to suit the capacity of the Mazda Motion Picture Lamp.
The Reflector, properly placed behind the lamp, insures a clear, bright field on the screen, with a maximum of light. It can be adjusted to any position necessary to give positive and accurate reflection; all adjustments are easily made, at any time necessary.
The entire operation of connecting or disconnecting the Project-A-Lite need not consume over two minutes' time, and any operator can install it. This regulating transformer is built standard for 60 cycles A. C. with ranges of voltage from 105 to 130 volts, to suit local operating conditions.
A few of the many advantages of using the incandescent lamp for Motion Picture Projection :
No intense heat; no current ivasted in resistance; no current used in converters or rectifiers: no condenser breakage; no flicker on the screen: no fumes; no smoke; no dust, and you get uniform illumination on the screen, together with a saving of from 60% to 75% in the amount of current consumed.
We are sole manufacturers of the PROJECT-A-LITE.
