ADDITIONAL LABORATORY TESTS OF KRYPTON-FILLED, 6.2-VOLT AND 12-VOLT MARINE SIGNAL LAMPS.

Abstract

A large number of lighted aids to navigation maintained by the United States Coast Guard utilize low-voltage incandescent lamps as the light source. It has been suggested that these marine signal lamps be filled with inert krypton gas in lieu of the currently used argon gas, in order to improve the luminous efficacy. Laboratory tests were conducted to compare the performances of krypton-filled and argon-filled marine signal lamps. The test results indicated that, for marine signal lamps of approximately 12 watts and smaller, krypton filling will provide a significant improvement in performance. For larger wattages, krypton filling provides no significant improvement in performance, and may even be detrimental. The test results revealed that the performance data published by the Coast Guard for low-voltage marine signal lamps do not accurately describe the argon-filled lamps currently being provided for field use.
