Abstract: A d-c., high-intensity arc for low currents is described. It differs from the ordinary high-intensity arc used for projection in that the positive carbon is not rotated and is copper coated so that it can be held some distance from the crater end. The current, voltage, and burning characteristics are given for the size carbons available at this time. The possible utilization of this type of arc for projection is discussed, and it is pointed out that because of the comparatively simple lamp mechanism required, it will take its place with the new a-c., high-intensity arc described in a previous paper in supplying the need for more light in the small and medium size theaters.
