Not the name of a thing, but the mark, of a service 



^LSO on this new lamp — the WHITE Mazda— you find the mark 



of Mazda Service. The high efficiency of this lamp, and its 



softened and gratefully mellowed brilliance are fresh indications of the 



fruitfulness of Mazda Service in its constant search for better light. 



MAZDA 



is the trademark of a world-wide service to 

 certain lamp manufacturers. Its purpose is to 

 ■collect and select scientific and practical information concerning prog- 

 ress and developments in the art of incandescent lamp manufactur-

MAZDA Service is centered in the Research Laboratories of the 

 General Electric Company at Schenectady, N. Y. The mark MAZDA 

 can appear only on lamps which meet the standards of MAZDA Ser- 

 vice. It is thus an assurance of quality. This trademark is the
