notes: label: Description (Brief)
content: An early tungsten filament lamp designed by Austrians Fritz Blau and Hermann Remane around 1907 as competition to Just & Hanaman's invention. Made in Germany by Auergessellschaft. Characteristics: Brass medium-screw base with skirt, glass insulators. Twelve sintered tungsten, single-arch filaments are wired in four parallel circuits (three filaments per circuit). Twelve upper and twenty-four lower support hooks, each in two pieces separated by a glass-bead insulator. Twelve "forked" lower supports, each in two welded pieces. Eight stranded copper-wire leads welded to support hooks. The leads are welded in pairs to four (platinum?) wires which pass thru the press. In the stem these are welded to stranded wire leads, two of which run to the center base contact, the other two pass thru a glass-tube insulator and run to the base-skirt. Tipped, G-shape envelope.
