I agree that heat is a problem. Even with fluorescents I found it desirable
to put a small fan into the system for heat dissipation. Why risk injury and
damage with hot lights? Joachim

  I'd think about the heat generated by halogens. I've seen diagrams of
contact printing set-ups using regular photofloods where it has been
suggested that a fan be used to keep the neg/sensitive material side of the
set-up cool as some emulsions can suffer from the heat. Halogens seem to
create more heat than photofloods (incandescents) so I would exercise some
caution not only to prevent a fire but to protect the materials.
