Author Topic: Hanovia 1kw bulbs Jeff Knoll Film Handler Posts: 26 From: Oakville, Ontario, Canada Registered: Feb 2002 posted 08-09-2004 04:48 PM                        I was able to purchase a bunch of new/old stock 1KW Hanovia bulbs (type 977B0010) for real cheap. They are all sealed in their boxes and new - well not really "new" but unused/unopened and 11 years old (they were apparently manufactured in 1993). My concern is that they do look smaller (the envelope does - they are the same length) than the Osram ones we are using now. There are no specs in the boxes and I cannot find anything on the net. Does anybody have experience with these bulbs? Can I use these in the place of an Osram 1000W/HS?? Thanks!  |  IP: Logged Aaron Sisemore Flaming Ribs beat Reeses Peanut Butter Cups any day!

The envelope size shouldn't matter if the rest of the mechanical dimensions match.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 08-10-2004 01:38 AM                     Be careful with these, Hanovia bulbs weren't the best quality and prone to failure. (No ignite/exploding) Had some locations in late 80's toss 'em because of the problems. Someone here with more experience with them recently could tell if that vintage was better/worse.  |  IP: Logged Dean Kollet Jedi Master Film Handler Posts: 591 From: Florida State University Registered: Jul 2003 posted 08-10-2004 02:01 AM                     was 1993 a Vintage year...I don't recall  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-10-2004 03:54 AM                     Hanovia lamps were not the same size dimensionally as other lamps of the same wattage. The stems were different diameters and the lengths were different. As I recall, the 1KW lamp was particularly small on all dimensions for 1KW lamps. However, that particular lamp was one of their best. Steve  |  IP: Logged Dennis J. Losco Film Handler Posts: 39 From: Phillipsburg, NJ, USA Registered: Jul 2002 posted 08-10-2004 07:50 AM                        The lamp you are questioning is a Mercury Xenon lamp,not a straight Xenon lamp . Do not use this in your projector as a replacement for the Osram 1000WHS.  |  IP: Logged Jeff Knoll Film Handler Posts: 26 From: Oakville, Ontario, Canada Registered: Feb 2002 posted 08-10-2004 09:28 AM                        Wow - that is a true "range" of opinion! What is the difference between a mercury xenon lamp and a straight xenon one? Thanks for all the replies!  |  IP: Logged Dennis J. Losco Film Handler Posts: 39 From: Phillipsburg, NJ, USA Registered: Jul 2002 posted 08-10-2004 10:24 AM                        The difference is in the spectrum. A xenon lamp produces wavelengths in the visible spectrum close to daylight. A mercury-xenon lamp produces wavelengths in the ultraviolet spectrum. A xenon lamp also has a smaller and higher intensity hot spot than a Mercury-Xenon lamp. Mercury lamps are used in UV curing and other scientific applications.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-10-2004 11:07 AM                     Also is not the rectifier current limiting and ignition requirements diferrent between a xenon and a mercury xenon  |  IP: Logged Jeff Knoll Film Handler Posts: 26 From: Oakville, Ontario, Canada Registered: Feb 2002 posted 08-10-2004 11:42 AM                        Odd, this is identified on the box as a "theatre bulb" - not an industrial/scientific product. The operating current is stated as 28.5A and the operating voltage is at at 36.0V  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-10-2004 01:33 PM                     "he operating current is stated as 28.5A and the operating voltage is at at 36.0V" that sounds very wrong are you sure a 1K xenon is normally 25v and 40amps  |  IP: Logged Andrew Shingleton Film Handler Posts: 63 From: Richmond, Victoria, Australia Registered: Feb 2004 posted 08-10-2004 04:51 PM                     The specs for the Osram XBO 1000W/HS OFR we're currently running is 19V with a rated current of 50A (current control range of 30 - 55A).  |  IP: Logged Dan Lyons Jedi Master Film Handler Posts: 698 From: Seal Beach, CA Registered: Sep 2002 posted 08-10-2004 05:45 PM                     What kind of theatre is running 1k lamps?! 1k is great for a home screening room with a small screen, but theatrical?
