The Epson LPE Filter. Over 1600 Color Correct Lumens Out Of the 5010/5020 6010/6020? A Detailed Review.

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/projek...W9000_Test.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 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.

The first three graphs are stock Dynamic Normal lamp, no filter.

Here's the measurements with the suggested settings for the 5020. Not calibrated, just the directions that come with the filter. Pretty good! This was in normal lamp mode, I'll post up if ECO has any significant variance.

Obviously, things can be tightened up a bit. But considering this is what you get without needing a calibration, it's excellent.

Lumen output was measure at 1655 lumens.
Now, bear in mind there's a bit of zoom here. The Lens is at about 15.5 feet, I think around 14 feet would be wide open. So, max lumens should be just over 1700 lumens. I'll edit to add ECO lumens later. I'm guessing over 1200.

Re: The Epson LPE Filter. Over 1600 Color Correct Lumens Out Of the 5010/5020 6010/6020? A Detailed Review.

Calibrated Lumen Output:
ECO: 1337
Normal: 1780

Here's the best I could do. Colors came out exceptionally well, except for red. Gamma is near perfect. The Grayscale calibrated is not much better than not calibrated. The problem is that the colors are curved in such a way that the typical Gain/offset just can't be adjusted so that DeltaE is below 5 at each point.

Overall, color is very good. Not outstanding, but very good. In all honesty though, while watching a movie color seems very natural. The fact that red and the gray scale is not perfect is just not noticeable to my eye. Skin tones are excellent in every scene that I used to evaluate them. Blacks look black, whites look white and grays look gray. Colors look excellent and natural.

For the vast majority of us I think this is as good as it gets. Purists will want better, no argument there. The color is available at every point, it's just that adjustment is not sufficient. A video processor that can adjust gamma for each of the colors would have no problem nailing a perfect grayscale, and all colors too I'm sure.

Settings I used. Anything not listed is at default value.

Dynamic
Contrast -1
Color -4
Temp 6500K
Skin Tone 4
Gamma Custom

RGB
Red Offset -15
Green Gain -4, Offset -2
Blue Offset -16

RGBCMY Hue, Saturation, Brightness
Red: 0, -3, -12
Green: 29, 38, -24
Blue: 8, -35, 0
Cyan: -13, 30, -25
Magenta: 12, 0, 8
Yellow: 0,0,0

Screen shots to come.

And here's the Grayscale after calibrating with an iscan Duo video proccessor. No hit in lumen output to get this. 100 IRE green was not dropped, rather Blue and Red were bumped up. So, if anything a slight bump in lumen output. The bump in Gamma at the higher IREs and the drop in Gamma at the lower IREs was intentional. Also, I could have easily tightened this up, but I saw no need.

Here's the results of my 3D calibration with my 5020 and LPE filter. 3D Dynamic mode.

I could have tightened things up a little bit, But I have a new PJ on the way and it's not worth the effort for now. Measured output is 1600 lumens. Mind you, I have full horizontal shift and the PJ is at 15 feet. If the PJ was centered and wide open on the zoom, I think output would be closer to 1700 Lumens.

Also, there should be a Mini 3D on the way soon! Woo Hoo!

Thats great news Nak. What about using it with the 8700 can it be done?.

I kind of doubt it. The lamp on the 8700UB has a different native output than the lamp on the 5010/5020. The 8700 runs out of Cyan at about 75% saturation in dynamic, no filter could correct that. I haven't calibrated it yet, or even objectively measured it, but cyan is clearly much better saturated with the 5020 in Dynamic mode. There was never a "Light Power Edition" 8700UB in Europe--there was with earlier models-- so I'm guessing the native output of the 8700UB lamp is just not capable of being sufficiently improved while retaining high lumens. Also, you'd have to jury rig some kid of mount...

Before I sell my 8700UB I'll at least hold the filter up and eyeball the improvement to dynamic.

Thanks for the reply looking forward to your final report. I'm thinking about returning my 5020 and just get 8700 for now.

Good question. I don't see why not; it's the same bulb I think? The filter corrects the native output of the bulb. It also is supposed to improve contrast; that would be a great bonus with the 3010/3020. The housing is the same, so it should snap right on. I'll post some pics showing how it mounts.

Those are some impressive improvements so far. And it seems like such a simple fix. How much did the filter cost? Did you have to get it shipped from Germany? Can you call Epson customer support to inquire about availability here? I'm wondering if there was any additional heat build up in the projector with the filter on it. Can you measure the projectors temp with/without it? I can't think of another reason it would not be offered.
