BETTER THAN THE ARC LAMP

Filament Lampe of High Candlepower, It Is Believed, Will Boon Take Their Place. / - ' The new metal filament lamps of high candlepower are likely to take the place of arc lamps for outside lighting in many eases, and one of these Is Tor the lighting ofraflroad yards. A good example is a large freight station and yard on the Continent which was newly installed last fall. Current at* 6,000 volts comes from an outside electric plant into a transformer house where it is reduced to 200 volts. Fbr the lighting which is needed for loading and unloading of freight there are used 24 ironwork poles, each 26 feet high and carrying a 800 candlepower metal filament lamp, while the lighting of the outer tracks comprises 14 similar poles 40 feet high’ with the same lamps. In other places, 50 candlepower lamps are employed. A suitable device allows of lowering the lamps from the poles when they are burned out, but ordinarily they require no trimming as in the case of arc lamps. A small winch and - steel cable lowers the lamp in about the same way arc lamp, so that a new lamp can be readily put in. For use inside of freight cars, sets of hand lamps on flexible cables are used, the cables working by trolley upon wires stretched alongside the tracks. —Scientific American.
