What is the LPE filter? It's a filter 12 cm in diameter that mounts on the 5010/5020. It comes with special edition "Light Power Edition" 5010/5020s projectors. It corrects the native light output of the bulb in the same fashion as the internal filter, except that it is more efficient due to it's size. You run the PJ in Dynamic with a few adjustments listed in the instructions. Supposedly, you get over 1200 color correct lumens--in ECO lamp mode. Over 1600 in Normal lamp. PLUS, you get a healthy bump in native contrast! (Up to 5000 from about 4300 on the 5010. Even more on the 5020.) Here's the link. It's in German, so you'll have to use Google Translate. http://www.cine4home.de/tests/projektoren/Epson_TW9000/TW9000_Test.htm http://www.cine4home.de/Epson/LightPowerEdition/TW9100/Werte/Kurzanleitung9100er.htm
Why is this only available in a couple of European countries? I have no idea.
I'll calibrate it and measure lumen output to see how it lives up to the claims. I'll be using an i1 Pro, and an i1 Display Pro to test and calibrate with Calman 5 software. I'll be taking measurements off my DIY 138" screen. It's Glidden Diamond 450 Titanium White and has a DeltaE of 1.43; RGB measure out at 245, 246, 243. (Measured with an i1 Pro and BabelColor.) I'm guessing gain at around 1.1 to 1.2; hopefully I'll be able to get the gain measured soon. Lumen output will be measured directly with a Lux meter. I have no means to objectively measure contrast.
There are a few minor adjustments you're instructed to make in addition to snapping the filter in place. Contrast -10, Color temp 7000 (I ended up at 7500.), Skin tone 5. (Many thanks to AVS member ANDYK48 for translating the instructions to English!)
I got my 5020 today. I was able to do some very rough testing of lumen output and watched a few scenes from Avatar. It'll be a day or two before I can do any real testing and calibration. But I thought I'd share my first impressions.WOW!
First the measurements, and bear in mind these are rough. I'll get better readings soon. ECO lamp mode: 1200 lumens. Normal Lamp mode: 1600 lumens. To my eye, the color is pretty darn good! Using the starship scene at the beginning of Avatar, it seems to my naked eye that contrast is improved. The star field is very black and the starship is brilliant. Forest scenes where there is sun lit areas along with shaded areas look incredible. Skin tones during the live action scenes look very good. Subjectively, this picture looks outstanding! If I never calibrated it I'd be a happy man to have it look as good as it looks now. Calibration can only make it look even better.
I have an Epson 8700UB that I calibrated Dynamic on. The gray scale actually turned out pretty good, colors seemed close but curved through the saturations instead of straight. Output measured at 1100 lumens. Let me tell you one thing straight and clear: That 8700 in calibrated dynamic never looked even one tenth as good as this 5020 with the LPE filter. In THX mode, I never saw more than 12 Ftl with a brand new bulb. I thought that looked great, but it can't hold a candle to this LPE equipped 5020. I'm only getting 9 ftl out of my Epson now in THX, I'm getting over 20 With the 5020. I'm gushing, I know. But if you have a large screen, this filter is a complete game changer for the Epsons. A whole new level of performance.
Someone at Epson is absolutely insane for not making this filter available in the US.
Measurements, calibration, screen shots, and more movie watching to come.
