Author Topic: Osram 2000W/H Bulb? Thomas Dieter Expert Film Handler Posts: 234 From: Yakima, WA Registered: Jun 2004 posted 01-14-2006 11:50 PM                     I had to change a bulb today at our Marietta, GA theatre today, and ran into a problem. The Osram 2000W/H Xenon that was in the lamp house (Strong Super Highlight) had a spot on the negitive end to screw in a cable. But the new bulb, an Osram 2000W/H Xenon did not have this spot to screw in a cable. I checked the model numbers and they were the same. I checked the stamp on the bulbs, and they were the same. The only thing that was different was the serial numbers. What was the difference, and does Osram still make the first bulb? Sorry, I would be more specific if I had the bulbs sitting infront of me, but I'm at home, and I don't have my new dig-camera to take photos and upload.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 01-15-2006 02:28 AM                     just a dumb question here, but was that other bulb have a threaded end on the cathode (negative) side? If so, you've got an HTP version (horizontal threaded pin) designed for Christie lamhouses. Also, it could be a GS (gap shortened) bulb in a wrong box. True, without pics, it's kinda hard to tell, unless Osram packaged the wrong kind of bulb in that box with the matching serial numbers. Usually, the 4 numbers are the production line sequence numbers where the first two letters kinda point out to what kind of bulb it is with the third digit, being that number being the year manufactured. Just never heard of an Osram coming out with a /WH bulb that didn't have the threaded hole for the negative cable.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-15-2006 10:30 AM                     Osram may have decided to eliminate it all together. There are just a few lamphouses that even need that negative lead any longer. I believe the Christie/Ushio 20R lamp does include that lead although to be sure I'd have to go look at one on the shelf.

But... a Super Highlight shouldn't use a lamp cable? The clamp attaching the insulating spacer to the cathode pin should have a power cable to the igniter post.  |  IP: Logged Louis Bornwasser Film God Posts: 4441 From: prospect ky usa Registered: Mar 2005 posted 01-19-2006 10:35 AM                        I have just inspected a brand new, recent arrival bulb. Not only is the cable missing (not unexpected) but the threaded hole for the cable is indeed missing also. If this is a problem for you, have your dealer contact Osram about getting the hole back in future production. My guess is that it was thought that no one needed it and "cost reduction" took over.

Osram sucks big time! With Christie you will definately get longer life, better light, and a company that stands behind theor warranty 100%... Something Osram has failed miserably at over the last 25 yers I've been in this buisness. My second choice would be Superior Quartz........

I learned that today, for much the same reason as the chap above.  |  IP: Logged
