A High Power Spotlight Using a Mazda Lamp as a Light Source

Modern the atrical performances are being lighted largely by projected light. For this work, many types and sizes of incandescent lamps, spotlights, and floodlights have been developed. These same types of projectors also find wide application for the lighting of pageants, dance halls, and many other similar institutions. The one unit, however, where the arc lamp spot has reigned supreme has been in the high power spot. Where a long throw is used, and a small intense spot of uniform distribution is required, the Mazda lamp has been unable to compete with the arc. This has been due to several reasons, primarily the greater concentration of light source obtained with the crater of the carbon arc, its high brilliancy, and the lack of a lens system especially adapted to the incandescent lamp.
