Author Topic: Problem with Osram XBO 2KW Classic Line Andres Briano Expert Film Handler Posts: 162 From: Buenos Aires, Argentina Registered: Jan 2008 posted 11-24-2008 08:46 AM                        Hi all! The picture illustrates a problem we had with an Osram 2KW bulb in a SLC20. The bulb was removed with 130 hs. The replacement bulb installed is showing the same damage with 140 hs. They were both new and are only 2 serial numbers apart. Has anyone encountered this issue before? If so, WHAT THE F%%&$ IS GOING ON???  |  IP: Logged Marin Zorica Jedi Master Film Handler Posts: 671 From: Biograd na Moru, Croatia Registered: May 2003 posted 11-24-2008 08:00 PM                     Check rectifier, maybe some diode is NOT conduction so you have much ripple in DC, or you maybe magnet for arc stabilizing??  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-24-2008 08:38 PM                     What you are getting is the Classic Osram Failure! IMHGO since they are so close together in SN you may have gotten a bad batch of lamps. Why are you even wasting your time with those lamps?  |  IP: Logged Jon P. Inghram Expert Film Handler Posts: 124 From: Wichita, KS USA Registered: Jan 2007 posted 11-24-2008 10:14 PM                     We've had fun with the 4kW OSRAM Classic bulbs too (search for osram classic.) The first looked just like yours, the second blew a seal and turned blue.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 11-25-2008 01:43 AM                        What makes them "Classic"? The fact that they fail? Here's another problem with OSRAM bulbs: I bet I can fix it, what do you think?  |  IP: Logged John Wilson Film God Posts: 5438 From: Sydney, Australia.

Mark G.: The reason I use these bulbs is that they are the only ones that have a dealer in this part of the world. Importing Ushios/Christie would be more expensive. Thank you all!  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 11-25-2008 11:56 AM                     quote: Andres Briano I bet they covered it up when it was still hot. Isn't it a bit dangerous to operate on a lamp that is stil so hot?  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 11-25-2008 02:53 PM                     Yes it is very dangerous. I was in a theatre when another tech removed a 4k lamp that was still hot, he was waving it around like a baton with no cover on. The manager was wondering why I had suddenly grabbed her by the arm and dragged her out of the booth. (That same tech once spent over TWO hours to change a breaker in a subpanel.. I found him working on his tape measure..) The old hard plastic covers made for interesting modern art sculpture when they were left on and lit.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 11-25-2008 04:34 PM                        quote: Marco Giustini Do you mean someone strike that lamp with the cover on it?

I can't believe it! Perhaps someone forgot to tell him/her to strike his/her brain before replace the lamp...  |  IP: Logged Jack Ondracek Film God Posts: 2348 From: Port Orchard, WA, USA Registered: Oct 2002 posted 11-25-2008 10:12 PM                        Oh, Geeez, you guys! Joe did it himself, to enhance the quality of his normal Film-Tech theatrics! The bulb was probably on the way out, anyway.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 11-26-2008 12:17 AM                     quote: Andres Briano Mark G.: The reason I use these bulbs is that they are the only ones that have a dealer in this part of the world. Importing Ushios/Christie would be more expensive. Andres, If another lamp outlasts the one you are using and give little to no trouble then it IS alot cheaper to use it. Refunds and lost shows because of utilizing poor quality lamps costs both alot money due to lost shows and a theaters reputation!!!! quote: Jack Ondracek The bulb was probably on the way out, anyway. Hey... thats a good one Jack... But I'd have to add that those lamps are on their way out before they ever come in! I may have to have that one put on a Sweat Shirt for Joe!

And no, I did not do that myself. It didn't even happen at my theater. I'd be afraid it'd catch fire. A client of a friend did this, and friend still has the bulb. I'm not sure how anyone could miss that, though.  |  IP: Logged
