Motion Pictures in Connection with Isolated Lighting Plants

R. L. Lee

One of the most successful engineers I have had the pleasure of meeting once said that in building a piece of apparatus, he did not try to design it, but asked what it wanted to be and then made it accordingly. Evidently this was the plan under which the lamp engineers worked when they built the powerful incandescent projection lamps which are now being used so successfully. This must be the case, as if there was any way under the sun which to make a successful lamp for the universally used 110-volt service, they surely would have done it, and not built them for 30 volts.
