            Abstract : 
The high efficiency of the carbon arc, the flexible and uniform quality of radiation it provides, and its extremely high intrinsic brilliancy give it a prominent place in the broad field of illumination. For applications in which a powerful light must be obtained from a source of small dimensions, it is unsurpassed. Characteristics of the various types of carbon arcs and their applications are outlined in this paper.
