The face tanner option works for me. I have set it up for about 4" of clearance from the bottom of the box in which it is mounted to the plate glass under which the plate and positive are placed and I get exposures in the 45 second to 1 min. range for K93 plates (plasti-gravure). You can plug the entire unit into a time-o-lite timer or the equivalent because the built-in timer works in minutes, not seconds. Cheap and easy set-up for up to about 8x10, maybe larger– but not much.
