Registered: Apr 2001 posted 01-23-2009 09:56 AM                     Every site I deal with has always gone Osram lamps on my recommendation with NO problems at all. I changed a 2k lamp this morning that had 3600 hrs, some 27 months which was clear and the anode looked as new. There was nothing wrong with the light and the lamp striked first time every time. It was changed as the owner felt he'd had more than his money's worth from it. Of all the lamps I've ever used Osram is the only one I can honestly recommend based on my experience and that of others I respect. While there has been a few who clearly don't like Osram I'm sure it must represent a very small percentage of the total out there. It's common knowledge that you always hear complaints but seldom here of the shows that have no problems. AS for lamps exploding, I was carrying a short 2k lamp in it's plastic tube in my hand. For no reason as I was walking to wards the projector to fit it, it exploded. It wasn't as big a bang as some might expect as the lamp was cold. It had possibly been given a bad knock and damaged a seal who knows. And YES it was an Osram.  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 01-23-2009 10:27 AM                       Ken, I felt the same way about Osrams... up until a couple years ago. There have been an inordinately high number of premature failures with them in many installations I know of, as well as in my own theatres.  |  IP: Logged Pete Naples Phenomenal Film Handler Posts: 1565 From: Dunfermline, Scotland Registered: Feb 2001 posted 01-23-2009 10:48 AM                     I concur with Mr McFall.

Inghram Expert Film Handler Posts: 124 From: Wichita, KS USA Registered: Jan 2007 posted 01-23-2009 12:00 PM                     The Osram 4k bulbs used to average over 4000 hours, with one almost hitting 7000, it's just this last set of bulbs has been very unreliable. We're apparently switching over (or at least experimenting with) ASL bulbs for the time being, with the subtle hint that we'll be using Christies "before too long". I used my Fuji S100FS with a macro lens and a slave flash to get those close-ups.  |  IP: Logged Bastiaan Fleerkate Film Handler Posts: 85 From: Linschoten, Utrecht, The Netherlands Registered: Jun 2006 posted 01-23-2009 12:38 PM                        What about Ushio lamps? How is the reputation of these lamps? I've never had a lamp explode in the projector (we let some drop... and the lamp in our Panasonic beamer has blown up (tiny bits of glass inside projector that made purple blurry spots in the image)) and I hope it will never happen. What a mess...!  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 01-23-2009 12:53 PM                     quote: Bastiaan Fleerkate What about Ushio lamps? I've ran 2500w Ushios (being the parent company of Christie...) and had some hit and misses with these bulbs - they either had the duration, or died prematurely due to seal leaks... Thus, we went back to Christies. We used to burn Osrams, but had warranty issues with Osrams that swung us over to Christie and been using them since.. quote: Bastiaan Fleerkate I've never had a lamp explode in the projector It'll happen, I promise you. And when it does, it's an experience you'll never forget, especially if you're close by. I had to "peel" an employee of mine off the ceiling when a 6k bulb let go and he was standing right next to the console. The entire complex (21 screens) heard that explosion. Interestingly enough, the shards barely scratched the mirror like the picts at the beginning of this topic when that 4k bulb let go. -Monte  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-23-2009 01:53 PM                     quote: Ken McFall I changed a 2k lamp this morning that had 3600 hrs, some 27 months which was clear and the anode looked as new. They why on earth did you change it if it was still in such good shape? I've seen Christie/Ushio lamps go in excess of 20,000 hours and 7 years and they are still clear and stable. A customer has one at 26,000 hours as I type this... they also never explode even at these extreme hours. They eventually just become unstable. I think what Tim said in another thread "False economy at work; "dropping dimes to pick up pennies." clearly applies to Osram products.

Registered: Apr 2001 posted 01-23-2009 07:16 PM                     Mark it was changed simply because the owner felt he'd had his money from the lamp and that it was not worth the risk of running it way over it's life. This is of course the opposite of what you often find today where lamps are run to the limit. WHY? A 2k lamp costs about £350 a cheap e53 mirror about £150. A half full house about £750. Do the maths a failure will cost you dearly. When you consider a lamp costs about £0.15 per hour it's lunacy to run them into the ground. So what that you get another 200 hrs out of a lamp that's about £28.... peanuts. That's why the lamp was changed... common sense.... not much of that about now-a-days.  |  IP: Logged Chase Taylor Expert Film Handler Posts: 175 From: Troy, Alabama, USA Registered: Mar 2001 posted 01-23-2009 07:52 PM                        I just had a Osram XBO 3000W/DHP OFR blow up at 359 hours. It took out the reflector and UV Shield. Osram is not going to like that bill.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 01-23-2009 10:00 PM                     The bottom line if you can't afford to change the lamp when its warranty is up then you shouldn't be in business With most lamps averaging only several dollars a show and in many cases less it should not be the make or break point nor is using the right microswitch in the platter  |  IP: Logged Tim Reed Better Projection Pays Posts: 5246 From: Northampton, PA Registered: Sep 1999 posted 01-23-2009 10:31 PM                       Hear! Hear! quote: Bastiaan Fleerkate What about Ushio lamps? I service about 40 Digital Cinema screens. Probably half of those are using Ushio bulbs, and I have not had a single failure from them. At changing time, they come out mostly clear, sometimes with only the slightest hint of darkness in the envelope. (FWIW, the reason they are changed is because the DC integrator WANTS them changed.) With the Osrams, however, I've had three catastrophic failures in the past 10 months and I know of at least 3 others in the same time period, in territories adjacent to mine. I wish it wasn't so. Osram must have changed something in their manufacturing materials or procedures, or gotten lax in their QC... but SOMETHING has definitely happened with those guys over the past couple of years.  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 01-23-2009 10:59 PM                     quote: Gordon McLeod The bottom line if you can't afford to change the lamp when its warranty is up then you shouldn't be in business Gord, That is just plain being belligerent! Even Christie allows an extra 10% over the rated warranted hours on their lamps... and even on the CDXL line of lamps. Now lets see, at say 525.00 average price for a 2kw lamp and if it goes 20K hours that lamp costs .02625 per hour to operate or less than 1/4 the cost of operating Kens Osram lamp. I'd bet that lamp costs even went up substantially over that 7 years... So the theater owner than ran his Christie/Ushio for 20,000 hours and 7 years would have spent about $1575.00 US more on purchasing three extra new lamps in that 7 year time period if he pulled his lamps at the same time Ken does. Now thats REAL SAVINGS! Now believe me I don't agree on running lamps this long nor do I teach it but we do have customers that do and that is their choice. Their theory is that if the light on screen is still good, the lamp is stable, and the lamps don't have a history of explosions... then why pull it? The majority of our customers however do pull them at times like Ken specified. I just wanted to show all of you how much less it costs to run a Christie lamp then any of the others one can buy and how much more reliable they are. P.S. Those of you that can remember the Marble lamps back in the 80's will also probably remember the incredibly high hours they achieved.

Also when I was with EDW's with the usage of CHR 4k and 6K HTP bulbs: we had to change them out at 150% over warranty, mainly for the light output quality (which I agreed with) since, even the bulb looks physically good, the light color would get to be somewhat dull and slightly muddy looking in making the picture on the screen look like it lost a lot of contrast - giving it a more flat/blah look on the screen.. -Monte  |  IP: Logged
