Re: [Frameworks] 16mm Xenon projection suggestion please

Any Xenon you could move around won't be all that much brighter than anything using an ELC tungsten (e.g. Eiki or Elmo) with a fast lens. There are like f1.2 lenses for those projectors, which is around a full stop faster than a f1.8. Throw per se isn't really an issue. Screen size is. The projector only has a finite light output, and if you spread that over a wider area, it gets dimmer (whether by increasing rhe throw w/o changing the focal length, or by going to a wider focal length w/o increasing the throw).
