I received a call today from someone who wanted to know if he could purchase a slide projector that can project at a throw of 420' onto an outdoor screen of 42'x 82'. For reference, their 35 mm projector uses 7K xenon lamphouse. Any thoughts?

I know there used to be a few companies that sold xenon slide projectors but the only one I know of that still produces them is Navitar. They retrofit a Kodak Ektagraphic III AMT slide projector with a Xenon lamphouse. Telex had short-arc slide projectors but has ceased selling slide projectors all together. Does anyone know of any other manufactures?

Elmo makes a Xenon slide projector and I believe Strong has one as well
For really large images they might want to think about 3x4 glass slides and a pani styled projector as it will withstand far more heat

Projecting a bright 42 x 82 foot still image on a low gain outdoor screen will be difficult. Even if you can get a larger lamphouse behind that projector, the amount of energy required will likely "toast" a 35mm slide. 35mm movies can use lamps as large as 7000 watts because the film is moving at 24fps, and not stationary in the gate. A larger format (e.g., old lantern slides) may work, since it spreads the energy over a much larger area.
