Unusual looking antique Model M-1 Eveready Sunshine carbon arc medical treatment lamp converted to use a standard modern light bulb. Manufactured by the National Carbon Co. with facilities in Cleveland and San Francisco. Both table top and floor stand models were produced.
Loosen side bolts to position lamp at desired angle, then retighten. Perforated panels add textural interest.
Founded in 1881, National Carbon acquired the maker of Eveready batteries in the early 1920s and by 1917 was itself acquired by Union Carbide.
