Abstract: A method of making a unitized tungsten electrode which exhibits superior mechanical and electrical properties which includes providing a length of cylindrical cut stock having a predetermined diameter and length. The stock is ground to form a rough unfinished electrode having an enlarged tip or nose portion at one end integrally connected to an elongated shank section. The unfinished electrode is treated by exposure to a chemical etchant for a time sufficient to form a finished electrode characterized by a smooth nose and shank surface and rounded undercut and ends. The invention includes the electrode formed by the described process.

Abstract: A miniature two-pin, tungsten-halogen lamp in the shape of a cylindrical envelope formed of high temperature glass having a sealed chamber capable of withstanding internal pressures of between 5 and 20 atmospheres. The diameter of the cylindrical envelope is in the range of 0.250 to 0.313 inches and contains at least one refractory metal filament mounted within the sealed chamber. The metal filament is electrically connected to a pair of leads passing out of the envelope. A fill gas is contained within the sealed chamber and contains an inert gas major constituent and a halide gas minor constituent. The lamp produces an efficacy of up to 26 lumens per watt when operating within a range of from 1.25 to 18 watts.
