The new look in lamp bases

THERE are many uses for aluminum in the lamp industry. For example, it is the reflecting coating on all lamps of the sealed beam type; it is used in some lamps as a powder for its beneficial effect on lamp performance, and in the manufacture of a heat-reflecting disk to reduce the base and socket temperatures in some lamp designs. But by far the largest amount of the material is employed in its newest use, the manufacture of bases. This paper is a discussion of data and tests on aluminum as it performs as a base-making material.
