There is and there are industry white papers that set forth the total percentage eaten up. The various elements that eat it up are multiplicative. Thus you fiqure out how much light is lost because of the reduced time the image is on the screen, take whats left, multiply by 1 minus how much light is lot because the lens shutter is not open for the full period each image is on the then multiply by the transmission efficiency of the lcd shutter. This is all a needless calculation since the total amount eaten up by each system (shutter glass, polarizer, Infitec etc) is known. Infitec is the most inefficient using up something like 93% of the light.Shutter glass system I think eat up 84% of the light.
This means that consumer grade machines around the $10K class, which might give out 1500 lumens in 2D, will still be pretty dim in 3D. Trade offs like lower refresh rates mean more light but also more artifacting.
You guys with your Titans have light cannons so you should be fine. You of course lose sime contrast compared to peanut whistle like the JVC RSs, but you have on offs certainly higher than the commercial theaters and you have brighter 3D images. Life is good,
