It's finally installed! This has got to be the best thing ever invented! I hung it over the washer/dryer since this is where the wet trays will be, the enlarger will be on the wall behind me.
With flaps closed its as dark as two 5x7 premier safe lights.
With flaps halfway to fully open.
Nice. They are impressive units.
To make mine even darker I cut a pair of filter-sized sheets of black mount board and inserted them into the flap holders in place of the filters. By closing the flaps this allows me to completely darken the room for composing dim projections on the easel. I can still get way more light than I need just by opening the flaps incrementally.
I'm going to do some fog tests in the morning to see how much light I can get away with. I may have to end up doing something like you to cut down the amount of light some.
