Actually, I don't think it would be too hard to retrofit a modern HMI lamp
into one of these. There's a lot more room in there than there is inside
the Bell and Howells.
But I work with a festival that has a rack of Bell and Howells and stocked
up some time ago when you could still get the lamps for a hundred bucks or
so each, and they are reliable and look good if well-maintained.
