That is also one of the reasons, I am going to switch to V6 fabric. V6 has a little higher gain.
@AVSCraig, I have actually been emailing Chris about my unit and your unit. My unit measured out almost identical to your original findings, of just shy of 2300 lumens / max Laser / iris open in natural mode. So what was done different, so now you have 2800 lumens? What mode was that measured in? The 500 lumen difference is a huge deal to me. Also, I have looked at that Accucal screen report and some of those numbers don't make any sense. They show the EN4K material at 0.84, but when I shoot my fabric with a Minolta LS100 and then compare it to a sample of Studiotec 100, which is a Refernce 1.0 gain, that gives my EN4K fabric a gain of 0.7. This is also exactly what sound and vision measured when they reviewed the EN4K screen as well. ThanksChris
High Bright yielded 2800 lumens. We switched on HDTV ( Dish ) and for something like the Super Bowl, it looked fine. Obviously you wouldn't use that for watching a movie, but it would be plenty fine for the NBA playoffs with all the lights on. And trust me, Chris said " turn some lights on - this is hurting my eyes " - it was blazing bright ! Don't know what to tell you about the screen report. Jeff has ST 100 samples, and ST 130 G3 samples, and I gave him the Cima Neve samples myself. But even at 1.1 gain, I get over 70 foot lamberts !
Ok this makes more sense now. I just shot mine with the Minolta LS100, and in High Brightness mode I get right at or just over 3000 lumens. The downside is the image is super green, but it would be usable I guess for certain events if extra brightness was needed. What I want to know is if these units should be calibrated from "High Brightness" color temp, to get more output but correct colors. I noticed if I took the HB mode, and turned the Green Gain down to -40, it was basically the same brightness as D6500 setup. So I do see how this yields more light output, the question becomes, if its fully calibrated from HB vs D6500, once the calibration is done, do you actually net out any additional lumens!
What fabric do you currently have?
EN4K
Do we have a true reading of what the gain is on the V6 fabric? When I compared my EN4K with a sample of StudioTec 100, using a Minolta LS-100, I can see that the EN4K has a gain of .7. I'm don't know how that Accucal report has it measured at .84 because mine is no where near that. I wonder if the fabric changed at some point. I noticed the Sound & Vision review has the EN4K measured at a gain of .7 also.
Do the light spill change with different zoom settings on the lens?
Given that others claim not to see it, I'm also wondering the same...My throw is 26', so I am at the far end of the zoom, with my projected image using only a small amount of the lens.
