notes: label: Description (Brief)
content: Westinghouse "Mazda" 25 watt blackout lamp, about 1943. Lamp made to provide a minimum level of lighting for safety inside homes during air-raid alerts. Light is emitted from the top port, although lamp envelope gets very hot. Characteristics: Steel medium-screw base with glass insulator. Tungsten filament (presumed intact). A-shape envelope with black coating around sides except for 1” window at top. Note over-spray around base-collar. Includes package that lamp was found in, which may or may not be the original package. Printed on top: “ Mazda [Westinghouse logo] 25w 230v”. Patents listed on package run from 1461117 (1923) to 2164283 (1939). Restrictions on brass supplies meant that lamp makers used steel for lamp bases instead.
