I believe the amount of drift will depend on the installation. An auditorium with a steeper throw will drift more than one where the lamp is on an even plane. Based on our technician's recommendations we refocus our digital lamps every month. In a perfect world, lamps for film projectors should probably be refocused on a similar schedule.
