Author Topic: Christie CDXL-30 and -20 lamp issue, anyone else? David Zylstra Master Film Handler Posts: 432 From: Novi, MI, USA Registered: Mar 2007 posted 07-04-2008 02:46 PM                     Theoretically it could - although the CDXL-20's cathode end is the same size as a CXL-30 so beyond the anode cable that is the only question on fit (maybe the -25SC is already the same size). The warranty on the CDXL-20 is the same as CXL-20 - 1200hrs full and 2400hrs pro-rated. Cost differential from CXL-20 to CDXL-20 is at least 50% higher, but the differential between CXL-30 and CDXL-20 is almost a wash (but then factor in the higher warranty and you come out way ahead). Christie is touting a "CDXL lamp down program" on their website. So far I am not completely convinced the CDXL-20 would outperform a CXL-30 in terms of light output over the life of the lamp. Not sure on the current -25SC lamp life though since we don't use those.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

I don't know if it in fact exists. The CXL-20SC, CXL-25SC and CXL-30SC all use the same cathode pin and should be physically exchangable. I would look into your exhaust and ensure you are pulling out enough. Most people try to avoid the 2500-watt lamps as they are normally too big a lamp for their package size. They are notiorus for not being the best in the long life department. Another solution for you Monte is to use CXL-30SCs and only operate them like 2500s. The cost is pretty close (less than $100 difference) and the life expectancy is the same...just the 3K is a little bigger to dissapate the heat. That is, you are likely to get longer life out of the 3K running like a 2500.

Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 07-04-2008 10:18 PM                     Christie is going to use a non "HTP" style lamp in their projector? No way. The "H" in the name that I listed denotes the CDXL lamp (high-output) but in a more traditional package as used by NON Christie lamphouses. So, CXL-20SCH would look like a CDXL-20 in the envelope area but would look identical to the CXL-20SC at the stems. Again, I don't know if they have a CXL-20SCH but if they do, that would be the letters they would use based on my other lamp testing.

Christie has been working with a no compromise attitude with Digital projectors so nothing would surprise me. There are even a number of very valid reasons for them still using the 1.2" dmd's in the 2000 and ZX although the M will use the .98" dmd's. Mark  |  IP: Logged
