Abstract: For the designer of projection equipment to make an intelligent choice from among the many available projection lamps, some performance data not ordinarily supplied by the manufacturer may be of value. Apparatus and a method have been devised by which the performance of lamps can be measured and evaluated in terms of their potential efficiency when used in a projector.
