I have just finished watching a Super 8 reel, something I haven't done much recently. The light output from the Eumig 12v 100w, is pretty poor really; it seemed OK years ago, but no better than the F1.9 I mentioned in 16mm not long back. The picture seems too dark. I was using a 50 inch screen, maybe these projectors were designed for a 40 inch screen, which is what I originally started off with.
