Reflectors and fixtures for industrial lighting.
A 1912 trade catalogue from the Wheeler Reflector Company of Boston, issued to factory owners, electricians and specifying engineers buying industrial lighting. Halftone plates show enamelled dome and cone reflectors, sockets and hanging fixtures isolated on tinted grounds, with light-cone diagrams and shop interiors; useful for machine-age silhouettes, soft graduated shading and technical line diagrams of light distribution.
