  rdf:value "Pieza de cristal dentro de la cual se produce luz cuando un filamento de tungsteno es calentado por medio de electricidad, a fin de que resplandezca. Mucha de la energía se convierte en calor, por lo que esta clase de bombilla es relativamente una fuente ineficiente de luz. En esta categoría se incluyen las conocidas bombillas de rosca, además de algunas un poco más eficientes, como las lámparas halógenas de tungsteno, las lámparas reflectoras, las lámparas con reflector aluminizado parabólico (RAP) y las lámparas con reflector elipsoidal (RE)."@es, "A glass enclosure in which light is produced when a tungsten filament is electrically heated so that it glows.
