Author Topic: 900 W xenons - maximum current. Stephen Furley Film God Posts: 3059 From: Coulsdon, Croydon, England Registered: May 2002 posted 06-17-2015 04:18 PM                     What is the maximum current for the old long style 900 W vertical xenons, as are used in various 16 mm machines? I don't have a model number to hand at the moment.  |  IP: Logged Bernie Anderson Jr Master Film Handler Posts: 435 From: Woodbridge, New Jersey Registered: Apr 2000 posted 06-17-2015 08:52 PM                        Hi Stephen, How are you? Are there any volt or amp readings on the projector? You really need to figure out volts and then you can figure out the amp setting. Amps X Volts = Wattage. You never want to go past the rated wattage, and if its a new bulb there are alot of theories on stuff like 85% of full rating up to half warrantee life and then rotate the bulb and bump up the amps to 90% of full rating. At our theatre we always ran the bulbs at 90% of rated wattage for the life of the bulb with no rotation.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 06-18-2015 03:42 PM                     For Osram XBO 900w/ OFR or CA OFR both vertical, 38-53 amps is the range. 53 max with 45 nominal.  |  IP: Logged
