We are in the same boat, most screens are through our screen room in less then three days if not sooner. Right now 6-8 hours, just long enough to dry before burning but do have a bunch that may sit for weeks like the 25, 60, 81, 305 and 355. That being said short of making another space just for the odd ball screens the bulbs I tested would not be usable. There are also many who may store screens for two weeks on average and was trying to make the test realistic across the board.
