content: Moore neon glow lamp, ca. 1895. Brass medium-screw base with collar and insulator retainer, porcelain insulator. Two tungsten electrodes: outer electrode is a ring just above the stem; the inner electrode is a cylindrical coil of lighter gauge wire (24 turns at about .5" diameter coil followed by 4.5 turns at about 1" diameter coil). A length of wire extends from the end of the coil and may have been attached to the lamp tip. Crimp connectors, 2-piece leads. Tipped, pear-shaped envelope. This lamp works via coronal discharge and these were generically known as neon glow lamps. Quite a few applications used types of neon glow lamps including decoration, electrical panels, telephone switchboards, electrical appliances and mechanical television. They were largely displaced in the 1970s by light emitting diodes.
