I have used one of these for printing-out paper. The
exposure time was 2 - 5 minutes. The heat build up during
the exposure time was minimal. I also printed to blue print
paper.

If I had one of these things now, I would print some of my
old negatives to a home made silver chloride coated paper.

I am very surprized that you got this result. My
experience with printing out paper is that it requires a few
minutes in direct sunlight. The intensity of my Morse
printer is very much below this. They were intended for
printing aerial camera negatives on rather slow contact
paper, something like Azo, with a few seconds exposure time.
The lamps are very low power Argon lamps. BTW, I found a
bunch of the lamps at a ham radio swap meet a couple of
months ago for a dollar each! I don't think the guy selling
them knew what they were.
