Dear all,
A design study of the Type IXC uboat based on U505, dated 1946 and conducted by the U.S. Portsmouth Naval Shipyard, notes in chapter S64…
"In addition to the above the indicating face plates of practically all I.C. equipment, important gauges, meters, etc., particularly in the Control Room are treated with phosphorescent material so that they may easily be read in the event of a complete casualty to the lighting power supply. The number of units so treated in the Control Room provides enough illumination to allow personnel to move about freely.
Additional fixtures for low level illumination, either blue or red, are not provided for dark adaptation of the ship’s personnel. Use is made, however, of tightfitting red lens goggles."
Best wishes,
Walter
