Mitchell To the Editor of IP: I wish to emphatically disclaim the authorship attributed to me in Allison Albee's letter (IP for February, p. 12) anent preheating projection lamps. In fact. I could not accept such suggestions when they appeared in IP for December last because I felt they were not practical . Filament Determining Factor I used to operate Powers projectors fitted with 30-volt, 900-watt bulbs many years ago. These were preheated by means of a lever which contacted a tapped primary winding in the stepdown transformer. The preheating process was undoubtedly much more beneficial with 30-volt bulbs (which have comparatively heavy filaments ) than it is with 120-volt bulbs for 16-mm projectors. I have used such lamps under various conditions for a number of purposes: and my own observations confirm Mr. Albee's opinion.
