"170" Automatic Constant Intensity
PROJECTION ARC LAMP
COOLER-CLEA
A complete change of air 12 times a minute. Prevents smoke and soot from settling on the mirror. 30 degrees cooler than other high powered lamps. The cold type reflector is cooled by twice as much air as used in other lamps. Uses existing exhaust systems which work efficiently with arcs operating at 90 amperes or above.
TROUBLE-FREE
Heavy duty pure silver carbon contacts. Fully enclosed single-piece water conducting tube for each contact. No water connections, no flexible conduit, no welded or clamped joints to break or leak at the contact.
MORE EFFICIE
The spot is shaped to the dimensions of the aperture, eliminating the light waste of round spots. Accommodates full 20-inch 13.6 mm positive to project a double 35 or 70 mm reel more than lamps which cannot burn this length. The single adjustment feed control can be set to burn the desired number of inches of carbon per hour, from 7 to 22, by means of separate geared head motors.
MORE CONVENIE
Integrated arc control system automatically maintains a uniform gap length with the crater accurately held at the focal point of the reflector, to maintain a screen light of constant intensity and color. Rear door permits easy retrimming, and cleaning of the reflector. Easy installation in low ceiling rooms.
