Elmo XP-750 16mm sound movie projector with xenon-arc lamp
Two-piece manual-thread portable xenon projector with a 750-watt lamp, circa 1992. This was the 60-pound (27kg) gorilla of portable xenons, about the brightest you could buy without sacrificing portability (assuming you have strong arms and a good back).
Pushbutton electronic control allowed the lamp and motor to be operated independently. Stopping the motor or closing the douser dropped the lamp current to a standby level, prolonging lamp life by avoiding the need to turn off and restrike lamp when showing multiple reels in succession.
I placed a few mouse-over notes when I posted this image, but they remain unavailable until the Flickr (Yahoo) folks officially restore the functionality (someday?); a workaround surfaced around October of 2015 to reveal the notes, but that avenue was closed shortly thereafter. which are inaccessible as-is. installing the Stig's Flickr Fixr userscript reveals those notes, among other things.
