This report describes photometric tests of the General Railway Signal Company Type W and Type SA Range lanterns used in Coast Guard Aids to Navigation. Candlepower and beam divergence tests are reported for various spread lenses using a series of C-2R and C-2V filament lamps. Also reported are tests with two CC-6 filament lamps. The transmission factors for the red and green color filters are also given. The report concludes that CC-6 filaments are suitable for use in the Type W and Type SA lanterns. Author
