Author Topic: Barco Series 4 Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 12-07-2019 07:18 PM                     Curious what you were getting. I was on the install team of a 4K 32B in a drive-in with 100 x 40 foot screen. With a 6500 watt bulb they were getting 6 ftl on scope 9 ftl on flat. The 4Ks do put out a little more light than the 2Ks. It was more than they had with 35mm. I was involved on an install of a 22L on an indoor with a 21 foot screen. Can get 14 ftl on scope laser 3D at about 60% power. 2D flat is at min power around 15%, 20% for scope 2D. Not sure how this translates to your drive-in. Maybe Tom from Barco has some idea. As far as lasting 30 years none are old enough to speculate. The clam is 20% light loss over 10 years but time will tell. These projectors are big and very heavy 600+ pounds for the 60L plus the two coolers you will have to have. Projector and each of the coolers will need there own 3 phase 220 circuit. Projector needs a 60 amp one. Maybe 70 for the 60L. While normally the projector dose not pull that much, if you loose a laser power supply the remaining supplies pick up the slack and create an unbalanced high current load on two of the phases. I am sure I do not have to say but they are very expensive projectors. But you might be able to do 3D at a drive-in with a respectable image. Now you have to figure out how to get the glasses back that cost $70.00 each.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!!

For projectors, anything over 15-years is going to be on the high side with 10-15 more reasonable. What makes you think even parts will be available 30-years from now? Most projector companies cap their warranty at 10-years (Cinionic is extending that to 13-years for those that convert xenon projectors to their new RGB+ stuff to make it financially viable...IF you are converting in year 6 or 7). 30-years ago, Digital Cinema was science fiction...that is an absurdly long projection to plan for with a generation 1 RGB laser system. How many generation 1 of anythings do you know that go the distance?  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 12-07-2019 09:15 PM                     Forgot to say your showvault/IMB should work fine as long as you get it with the ICP in it instead of the ICMP.  |  IP: Logged Jay Glaus Expert Film Handler Posts: 123 From: Pittsburgh, PA USA Registered: Dec 2010 posted 12-07-2019 09:32 PM                        Hi Rick, It's been a while. I'm curious what kind and size bulb you are using in your 32b? My screen is 80 feet wide and I use an 7kw Ushio and its a flame thrower. Arguably too bright if you get the right animated film. I'm curious how much 20 feet difference makes, I guess it must be a good bit in the grand scheme of things. Also I think the actual concern with the FDA comes from whats reflected off the screen, at least thats what I was understanding. I've thought about going laser at my place, and someday may have to. I have a feeling in the future, maybe not near future, but nonetheless I feel there will be a big push to drop xenon and go laser. I'd love to convert. I just wrestle with the thought of spending all that money. Ouch. If anything I might go with one of the conversion kits. I got an email not too long ago about them, but I didn't really read it too close. Figure I'll get a little longer on xenon before I make the leap of faith. I know no matter what, once film left projectors quit the whole concept on return on investment. Film projectors would easily pay themselves off many times over. But I know even the machines we have now most likely won't last long enough to justify the expense let alone laser. Not saying digital doesn't have it's advantages in some aspects, but it comes at a much heftier price than a Simplex XL.  |  IP: Logged Stephan Shelley Jedi Master Film Handler Posts: 854 From: castro valley, CA, usa Registered: Nov 2014 posted 12-07-2019 09:55 PM                     The safety thing is a bit complex but there is a hazard a certain distance in front of the lens. The distance is based on the intensity of the projector and the lens used. Then there is a safety distance below and to the sides of the light cone to the end of the hazard distance for ones installation. In the USA the light cone needs to be 8 feet above the floor for the specific hazard distance for the installation. If your below 8 ft then you have to block off that area plus the side safety distance which I do not remember off the top of my head. There is a concern of reflected light within the hazard distance such as reflection from the port glass. The screen would be well beyond the hazard range and the light spread out so it does not pose a hazard.  |  IP: Logged Dave Macaulay Film God Posts: 2321 From: Toronto, Canada Registered: Apr 2001 posted 12-08-2019 10:08 AM                     The screen reflected light is not a concern. Retrofit lasers will be a problem in many sites because they often have low ports so the image beam is barely above the rear seats, I know several where anyone in the rear row will obstruct the image just standing up. A zone in front of the port will have to have seats removed and be barricaded off to use a laser projector. New builds we've done for laser have been designed with the port quite high above the back seating row. A 3P or 6P laser shines out coherent laser light which is pretty dangerous to eyes... but not as bad as a tight laser beam in the eye. Phosphor laser projectors have normal non coherent light for green and red, but blue is still coherent laser light. I don't know how much more dangerous the laser light is over a xenon projector's. I would not advise looking into a xenon projector lens with a bright image showing. The laser regulations were enacted for laser equipment with focused beams either in industry or for scanned beam entertainment systems like Laserium (is that still around?). There have been rule changes to allow laser light source projectors but, in my opinion, they are still too restrictive relative to the danger.  |  IP: Logged Rick Cohen Expert Film Handler Posts: 102 From: Amherst, New York Registered: Feb 2011 posted 12-08-2019 09:32 PM                        Jay, Yes, the 20 extra feet of screen width does diminish the overall brightness of the image significantly. Also, with a longer throw (400 feet) comes a longer focal length lens, which reduces the light efficiency output of the lens. With a new 7K lamp, we are only hitting 5-6 f/L with flat, less with scope. By the time we reach warranty life on the lamp, figure about half that, which is not where I'd like to be. Waiting for the laser market to mature with corresponding price drop is very frustrating. To get more light out of my Barco 2K-32B, I could build a booth closer to the screen with a more optimal focal length lens, or I could stack two 32Bs, or I could cut my screen width back to 80 feet from 100 feet. None of those options are especially appealing.  |  IP: Logged Tom Bert Expert Film Handler Posts: 134 From: Belgium Registered: Apr 2010 posted 12-09-2019 07:50 AM                     For calculation/evaluation of any projector/lens/screens combinations, we have our online tool: https://www.barco.com/HtmlApplications/DigitalCinemaCalculator/index.html  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 12-11-2019 06:46 PM                        Just received an emergency service bulletin from Barco, advising that any SP4K projectors running software version 1.1.4 should be downgraded to 1.0.11 urgently and ASAP.

Did you get that from Barco, or from Cinionic? Barco will send out an InfoT advising to upgrade to 1.1.5 (or downgrade for those who feel more comfortable with 1.0.11), which came online today.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 12-17-2019 07:22 AM                         |  IP: Logged Peter Montoulieu Film Handler Posts: 3 From: Miami, Florida USA Registered: May 2018 posted 12-17-2019 09:13 AM                        Hello Tom, I am commissioning the first sp4k15 that has gone into a home. https://wallscreen-skylounges.com/carl-fisher-estate-gets-rgb-laser-upgrade The projector is excellent, one of the best-designed projectors out there. The red convergence could be improved. I am having issues with the 3d via HDMI. AG in Sacramento mentioned that I had to to do the updates in order to fix some 3D bugs. I believe the recall of 1.14 may have preempted the fixes AG referenced to. Using pinouts 7 conn synch + and 14 conn synch - we are unable to properly display the 3D L test pattern using expand48 settings. This is using a volfoni rf50 emitter that worked on the previous dp-1500. In addition, an edid issue on HDMI b is preventing 3D authentication on the oppo 3d player. Please look into this.  |  IP: Logged Rick Cohen Expert Film Handler Posts: 102 From: Amherst, New York Registered: Feb 2011 posted 12-18-2019 12:14 PM                        This is big. https://www.boxofficepro.com/cinemark-signs-10-year-exclusive-agreement-with-cinionic-for-barco-laser/  |  IP: Logged Marco Giustini Film God Posts: 2713 From: Reading, UK Registered: Nov 2007 posted 12-18-2019 01:22 PM                     I’m still confused of what Cinionic is and what is its relationship with Barco.  |  IP: Logged Tom Bert Expert Film Handler Posts: 134 From: Belgium Registered: Apr 2010 posted 12-19-2019 05:16 AM                     quote: believe the recall of 1.14 may have preempted the fixes AG referenced to.
