Xenon short-arc lamp: Difference between revisions

The first xenon lamphouse premiered in West Germany in 1954. By 1969, 50% of theaters in West Germany and 15% of theaters in the United States used xenon lamps. ² Xenon arc lamps rose to popularity in the United States in the 1970s as part of the industry-wide movement towards greater [[automation]]. They replaced the far more labor-intensive [[carbon arc]] lamphouses previously in use, which had to be monitored and adjusted by a dedicated projectionist during every show. Xenon lamps facilitated further automation by making it easier for operators to build film up to large reels and [[platters]], which was difficult or impossible with carbon arc because the maximum uninterrupted run time for a single projector was limited by carbon burn rate and by the maximum travel distance of the carbon feed mechanism. By the 1980s, xenon lamps were the near-universal standard for theatrical projection.
