That was my main reservation with the Lumis. Would like to have the option to physically converge the chips.

Well you mean your main reservation with ANY* 3-chip projector (DMD, DILA, SXRD, LCD). * Consumer PJ

No consumer PJ exists that I'm aware of that allows it.

One of the issues with this sentiment is that typically the chips aren't off whole/half/quarter pixels across the entire image. A lot of times you'll see, for example, the image is basically perfectly converged in the middle but off by a quarter/half/whole pixel on one of the sides of the image. Having physical control of the convergence does not mean you'll likely be able to get perfect convergence across the entire image. Temperature of the chip (expanding and contracting), vibrations, and other things can move/warp the DMDs and cause these odd misconvergences that are localized to one side or portion of the image. Unless the convergence is WAY off having phyiscal control of the convergence is next to pointless and one expensive machines like this you typically see pretty good factory set convergence. If it is off by more than a pixel I'd recommend replacing it while you're still inside that time frame to do so.

I'm still enjoying watching my Lumis even though I've spent some time also watching my VW600. Motion definitely looks better to me on the Lumis !

I still need to rub my eyes sometimes watching the Superlumis. It is so good that I just can´t believe it... And yes, motion is absolutely superb on the SIM2 projectors, in general actually. Even the entry models are quite good at that.

With that price for Sim2 PJs should make you coffee in the morning . I went from Sim2 C3X 720p to Epson 6030 and I am not missing anything. Other are catching up with the big price boy toys.

I agree with you Armand07 as I also have the Sim2 SuperLumis. The picture it produces is phenomenal and its 3D rendering can't be beat. This unit was the perfect answer for me since I went with a 12ft screen and love 3D as well as 2D and needed the brightness.

I'm back to watching my Lumis after playing a bit with the Sony VW600. Watched " A Most Wanted Man " the other night, and re-watched the last 1/2 gain last night ( since my wife was exhausted and fell asleep the first time around ). That Blu Ray has a stunning transfer. Had some friends over including someone who hadn't been to our house before - he was floored at the detail in the picture!

I just wish there was a board upgrade for the older Lumis/C3X 1080 to make them 3D/144Hz flash capable. Oh alright, I'll settle for 120Hz instead so they can save the 144 for their flagships! Nothing beats DLP 3D according to everything I've read.

The only way to do that is sell your old Lumis ( board and all ) and buy a new Lumis - preferably a Super Lumis !

Are there any reviews of the Super Lumis that measure light output & CR ? The few reviews I found seem to be a reviews of the Sim2 press release & marketing material. The only info Sim2 provides is brightness drops to 3800 lumen with the high contrast lens (necessary to get the "up to" 30k:1 CR).

How bad is the CR with the high brightness lens? How many lumens after calibration? Does brightness dim over time?

Trying to determine how large a screen I could realistically do if I got this PJ. Let me know if this post is inappropriate for an owners thread, and I'll remove it.

I haven't seen a review either. If you are concerned with dimming, you might wait and check out Sim's new Laser 3 chip projector.

I decided to have a Leonard Nimoy Tribute Week starting last night, and watched " Star Trek - The Motion Picture " on my Lumis Host ( watching II - IV and the re - boot " Star Trek " the rest of the week ). I have to say that they did a great job re - mastering a 36 year old movie - and some of the space scenes had the blackest blacks I've seen on just about any movie. My Lumis still throws an amazing picture! Tonight we're watching " Wrath of Khan " !


RIP Leonard Nimoy.

Craig,

I am curious how dim did your ordinal bulb get at 500 hours. I am approaching that number and I have seen a big difference lately.

It started out at 848 lumens at the lowest 230 watt setting. By 442 hours it was around 852 lumens at 270 watts - nearly full power.


Give me a call for a replacement lamp - maybe I can help !

I measured about 21 fL with a 124" dnp Supernova screen with gain 0.8 when the lamp was new. So pretty bright. The lamp is now just over 500 hours so I will try to make a new measurement. With my eyes I recognize there has been a little drop in light output since the lamp was new, but still feel it is has plenty output. Even with 3D it is sufficient on a dark 0.8 gain screen.

I have very similar screen so I would be very curious to see your updated measurements. Thanks!

What lamp power setting? On my Lumis I can adjust the lamp power from 230 to 280 watts.

The Superlumis has a 350 watt bulb, dimmable by 10 watt steps down to 280.

In 2.40:1 aspect ratio I had it set to 300, but now have increased it to 310 watts.
Watching 16:9 material and using approx 97" of the screen I use the lowest setting. This is now perfect. In the beginning it was almost a little to bright!

I noticed the AVS home page article about Theo's new theater where he apparently has upgraded to a Superlumis.

Seems to be around 15% loss at 525 hrs which I think is what one could expect.
