A 1916 trade catalogue issued by the Westinghouse Electric & Manufacturing Company in Pittsburgh for electrical contractors, utilities and municipal street-lighting engineers. Halftone photographs isolate enclosed arc lamps against plain grounds, showing ribbed hoods, flared reflectors, suspension hooks and clear globes with visible electrodes, plus wiring diagrams and installation views useful as industrial silhouettes or cutout objects.
