Author Topic: Loose thin wire on OSRAM bulb Paul Konen Jedi Master Film Handler Posts: 981 From: Frisco, TX. (North of Dallas) Registered: Jun 99 posted 11-22-2006 07:44 PM                     Was given an 4.5K OSRAM bulb to run in my digital projector, since I am done with 3D content for now. My question: There is a small thin wire that is looped on one end of the bulb, goes over the envelope and is connected on the other side. What does this wire do? If it came loose, is it ok to remove and discard? Thanks  |  IP: Logged Phil Ranucci Expert Film Handler Posts: 236 From: Carpinteria,CA, United States Registered: May 2006 posted 11-22-2006 09:12 PM                     I think it's used to help ignition, some lamphouses need it, some don't. We used to cut them off in LP lamphouses, don't know about digital. Did the lamp you're replacing have one? If it's come loose it should probably be removed because it may short out against the lamphouise.  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 11-22-2006 09:52 PM                       Phil's right. That's a nichrome ignition wire. If it's off and you can still light the bulb okay, no harm done. But, if it's off and you need it...  |  IP: Logged Paul Konen Jedi Master Film Handler Posts: 981 From: Frisco, TX.
