I didn't try to load that onto any of the projectors we service...but I did look into the release notes: It dates back to December of 2013 and contains "Fake" article numbers starting with R105 and that it is for lamps NOT APPROVED by Barco. So the lamp you are using may very well be listed in that file. The Release notes don't specify what lamps are included. I would definitely take a Philips made configuration file over a homemade one (you'll be sure to have all of the right parameters but it is interesting that Barco hasn't "approved" them. Then again, I don't know what sort of money has to change hands to be "approved." There could be external factors in play. But seriously...just get the Ushios!  |  IP: Logged Ethan Dutcher Film Handler Posts: 26 From: Maitland, FL, USA Registered: Jun 2014 posted 12-13-2014 11:34 AM                       Thanks for the input Steve I'll look into making a new lamp file after the weekend. Also, I'm well aware that moving the Z-axis is not the proper way to change the lamp current, I'm just sharing my observation about what is happening with the lamp. We have manual controls like normal, I had simply never seen the current change when moving the lamp around. CLO had never been setup on the projector, I have no clue as to why the lamp power is changing even in standard mode. Our screen is about 30 foot diagonal, no idea on the gain. I've only been here for about six months and the place has been open almost 30 years, I know the screen was replaced once but there is no documentation I can find in the building. This is also the first Barco I've worked with, my previous theatres had Christie/Sony installs, so I'm certainly still learning a bit about it.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 12-13-2014 12:45 PM                     I suggest before you try making your "own" file, if a factory one exists (like the link pointed to for Philips; the file you need is towards the bottom of the page), I'd start there. As I said previously, the manufacturer would know what the safe parameters are for the lamp. See if the lamp is in that file. You'll need sufficient privileges to perform a software update...it will go fast since it will just affect the lamp files. Again, if you have sufficient privileges, then going to the Installation>Lamp>Light Output will let you see Power and Current simultaneously. Voltage is not interesting at that point since current and power are the limiting factors and voltage can be derived. If you don't have sufficient privileges, then Just going to the "Service" tab will let you see power. If the CLO hasn't been calibrated, then the numbers are meaningless.  |  IP: Logged Ethan Dutcher Film Handler Posts: 26 From: Maitland, FL, USA Registered: Jun 2014 posted 12-15-2014 04:09 PM                       Ok, I switched over to the Philips lamp files and that got the lamp running at 3k. It is still not as bright as I would like, but it will do fine. I went ahead and ordered an Ushio for next time, thanks again for the assistance everyone.  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-17-2014 06:25 PM                     I'm using Ushio 30BAF/L bulbs in my two 15c units on screens over 30 ft wide, getting close to 17fL running with the power in CLO mode and bulb is only shooting out around 2500W of light. When I throw the white test pattern on the screen, it doesn't look the best after a full install with alignment, but as when the image is on the screen, you do have a good picture.  |  IP: Logged Carsten Kurz Film God Posts: 4340 From: Cologne, NRW, Germany Registered: Aug 2009 posted 12-17-2014 06:30 PM                     Hmm, that's not overwhelming for a 3k Bulb on a 30ft screen!? - Carsten  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 12-18-2014 04:54 AM                     Monte, What is wrong with the white pattern in your opinion? DCI white point may look "yellowish" but that's just a reference to make sure your projector is outputting the same colours seen in the studio. What then the colourists do is another story!  |  IP: Logged Monte L Fullmer Film God Posts: 8367 From: Nampa, Idaho, USA Registered: Nov 2004 posted 12-18-2014 02:33 PM                     Why I used the white is when the light sensor in the Barco isn't working, thus I can't use the light output scale in the Communicator to get the maximum light levels when doing the XYZ adjustments. Thus, I use the white light test to get the brightest illumination on the screen. It's like doing the bulb focus test when doing 35mm.  |  IP: Logged
