I use two Gralab 300s. One for the enlarger and one on the wet side for processing. For dodging/burning I use a kitchen wind-up timer that ticks 4 ticks a second (240 ticks in 60 sec, actually).
I previously reported the definitive phosphorescent phog phallacy phindings: I held a Gralab, after 30 min. in open room light, then in total darkness in close proximity to a sheet of Bergger 200 ASA B&W film. The Gralab was sitting on top of one edge of the film. At 30 sec. there was no fogging with N+1 dev. I also put my glow in the dark watch directly on top of the film for 10, 20, and 30 sec. There was ZV fog from 20 sec and Z2 from 30 sec.
