POWER IN THIS FLASHLIGHT Continued Experiments Have Resulted In Development of a Really Re-., markable Article, From the- pocket flashlight operated by two or three dry cells of minute size the battery searchlight has been steadily Improved until remarkable results are obtained. Some time ago there was devised a searchlight of 500 foot range operating op-erating on six or eight volts. More recently a battery searchlight has been Introduced with a range of 2,000 feet up to half a mile, operating on six volts. Equipped with a' seven and one-half Inch adjustable focus, single shell reflector, on a recent photometer test one of these searchlights gave 453 candlepower. The combination of a nitrogen-filled tungsten lamp and a correctly designed de-signed reflector has worked wonders for the battery-operated searchlight. fj New York Herald. ij
