naugastyle,
What sort of exposure times do you get with Adorama papers?

OK, bearing in mind I only have the 4x6 Adorama paper and I haven't used it since switching to the 80mm lens which has smaller aperture options...generally f/16 and 5-6 seconds (filtered). The 50mm lens can be turned past f/16 for some reason, and even though there's no other aperture marked it does get dimmer, so sometimes I've had to turn it to this smallest unmarked point to get to the 5-6 seconds. I got longer times with split-grading, though. I should try again with the 80mm and brighter daytime negatives sometime.

Happy to report Rocso ND.9 gel on top of condenser lens combined with new 75W bulb brought my exposure (120 6x7) times to a very workable 12-16 seconds range. I'll likely slow it down even further with ND.6/.3 as needed. Since these exposure times are easily replicable, I decided not to use the night-lamp dimmer. Thank you for all your suggestions and ideas!
