Author Topic: XBO Xenon lamp storing time Marin Zorica Jedi Master Film Handler Posts: 671 From: Biograd na Moru, Croatia Registered: May 2003 posted 11-06-2006 05:08 AM                     Is there any date for XBO lamp that can be stored in original package? I hear that XBO lamps from Osram may be stored for a 3 year max, so after that they aren't good for use? I have situation where I install XBO lamps which are been stored for 10-15 year and now they working really fine, and newer have problems with ignition. Is there any papers where this data can be found, so far I newer saw data like this.  |  IP: Logged Richard Fowler Film God Posts: 2392 From: Ft.

Some foam packaging will deterioate if 3 to 5 + years old.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-06-2006 10:30 AM                        According to Osram USA, there is no shelf life for their bulbs. Warranty is determined only by usage, not storage. I have many old Osram bulbs from closed theatres, up to 20 years old, that work perfectly.

Thorn stopped making xenon lamps a long time ago.Some of the packing is in a bad way but the lamps way outperform any new lamp. Lamps are 1600 watts in vertical lamphouse.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 11-13-2006 02:50 PM                        At one time there was "interchange" between Osram, Tungsram and possibly other similar bulbs. I think Thorn was one of these.

If i remember right I was told that it had been sitting on a shelf for about 10 years before I had it. An old projectionist used to stock pile lamps at the end of financal year to use his budget. The cinema had a refit and went up in lamp size so he got rid of them. Did have an interesting one a few months back. I had a lamp back in 2001 that developed really bad flicker after 400hrs. The company ( not saying) would not replace it, I switched brands and happy ever since. Well i came across this lamp in storage so I thought I would try it out again. Put it in and its happily burning now better than the day it was new. Its total hours clocked are now 1600hrs. Lamp is a 1600HSC. Maybe lamps perform better the older they get  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 11-14-2006 03:00 PM                     I believe Thorn and Phillips had a arrangement for Xenon Lamps  |  IP: Logged John Hawkinson Film God Posts: 2273 From: Cambridge, MA, USA Registered: Feb 2002 posted 11-14-2006 05:51 PM                     I would tend to suspect you originally had the lamp hooked up to a less-than-stellar rectifier, and the second time around you gave it a more-forgiving rectifier... --jhawk  |  IP: Logged
