Show WONDERFUL LIGHT It Will Give Illumination Equal to About 250000000 Candle Power The idea of an electric I light which fed by a current from at dynamo acm ated by a forty horsepower engine and giving 7000 candle power can have its Illuminating power intensified 35000 times is not easy to grasp It means the projection of a stream of light of about 250000000 candle power and it is no wonder that the announcement that such a light is about to be used in this country has been received with some incredulity in Europe Yet this is the efficiency of the light which will ibe shortly erected at Fire island for the illumination of the adjacent coast and the protection < of the fleet of ships entering en-tering New York harbor A remote suggestion of the power of this lamp may be arrived at by bearing bear-ing in mind that an ordinary oil lamp is about 38 or 40 candle power and then trying to imagine the combined beam of 3000000 lamps The ordinary dee tile street light may be put down at 100 candle power and 250000 of these would represent the strength of the Fire island light The most powerful oil lamp yet made is supposed to shine out on a clear night for a distance of thirtyfive or forty miles but the new light will flash its welcome rays to the incoming European Eu-ropean liners when they are 120 miles away The light revolves rapidly and throws out its beams with the intensity inten-sity of speed of lightning The motive power which actuates it is a simple clockwork arrangement contained in a box two feet square and although the revolving portion of the light weighs fifteen tons the mechanism controlling it is so delicate that the pressure of two fingers will turn it The value of this marvelous lamp can only be determined by practical worR ing but it promises to represent an immense stride in the science of coast lighthouse illumination > PhIladelphi Press |
