Description (Brief)
"Longer Life - Less Light” incandescent lamp. The life rating, light output and efficiency of an lamp are all linked.
GE "Longer Life / Less Light Lamp". According to a GE engineer, this was an attempt at truth in advertising to show that the public would not buy a long-life lamp if they knew that lumen output was reduced. The unappealing color and type-face of package may indicate a half-hearted effort to sell this product. The lamp was produced in response to the Brooks Committee Congressional hearings into lamp life (1964-66) - the details on the package mirror the argument GE made to the Committee. Characteristics: medium-screw base with glass insulator. CC-6 tungsten filament with center support, crimp connectors, dumet leads. Tipless A-shape envelope with internal frost [IF] coating.
