Sim2 Lumis 3D

Sounds like specs of two ProC4's not Lumis.

Maybe Sim2 should have a package that includes a d-box chair or plateform for virtual reality.

Does anyone have any more information about this projector? I have a Lumis and would like to learn more about this 3D stackable solution.

If you are wondering if you can add (and stack) another Lumis and achieve 3D, the answer (per Sim2) is "no." The package they developed requires the two units and HTPC 3D system (w/glasses) that come with the package. The units are setup one for each eye.

Really? It looks simply like 2 Lumis's stacked with a 'box' that delivers the 3-D. WHat is in the 3-D Lumis's that wouldn't be inside 2 Lumis's?

Jeff, when I asked Sim2 about the possibility of stacking two regular units I was told "no can do" because in the 3D setup each unit was preconfigured for each separate eye. (Not having Peter's expertise regarding 3D, I went no further in the questioning.)

Its not just whats in it, its also whats taken out. They are not simply 2 standard Lumis units

The aperture has been opened in order to gain maximum light output. This results in the CR drop.

Both units have internal Infitec filters configurable for 2D or 3D.

And that, fans, means that it doesn`t use shutter glasses, it is a passive system with a different infitec filter used in each. And, TA DA, it does not require a polarizing preserving screen since it doesn`t use polarizing filters. It uses Infitec filters and therefore MUST be used with Infitec glasses which are passive glasses using TA DA Infitec filters. These are the filters and glasses used in Dolby 3D theaters. The glasses are narrow band color filters and to get the correct colors we all demand and cherish, a color correction box is required. TA DA. The box Sim2 supplies with it system. And all this from someone who no longer is a Sim2 dealer.

Come-on, any two projectors can do 'passive' 3D, just put them next to eachother, and place a filter before each leans. However the demo's I have seen aren't very convinving.

The advantage of the Infitec system is that a silver screen is not required. The disadvantage is that a color correction box is required. That and the German owners of the patents for the Infitec system and the manufacturers of the filters charge big buck royalties. It is true that any two projectors can be used. But you need to buy the two filters, pair(s) of glasses and a color correction box. Individual parts can be procured from the US importer. Something like $5K for the mess.

to convert the reald side by side format using something like the doremi box over hdmi breaks hdcp rules ( no outboard conversion is allowed), there is no way at the moment to do this processing outside the projector, so to enjoy these projectors one will need a special htpc of some kind, but that leaves out directv in RealD. There are some rough months ahead for those of us figuring out this 3D situation.

So besides the color correction, the Sim2 box must do that. I would assume no conversion is done inside the projectors with each one being fed a split stream, one for each eye.

Yea,not to mention what you may be giving up to get 3D ,with very very little to watch and even less worth watching.

This just isn't going to be any sort of solid upgrade path.

The path is probably the machine Lon purchased.

Sim2 does have a new 3 chip called the Lumis Uno (which is basically a Lumis with a lower power lamp and no DI). I don't know if this is more based on that, but it could be...

Do you have more information on the Lumis Uno?

Not a heck of a lot. From the look of things it is the Lumis without a DI and with a 230 watt lamp rather than a 280 watt (not sure what actual light output would be). On/off is rated at 9000:1 though again I haven't tested. Other than that they seem to be identical (although this is $10k MSRP less money).

Thanks Jason. I didn't see it on the Sim2 site. Is it available now or is this one of the new units latter this year?

The units for the 3D stack are 280w. They are opened up and maxed out for lumens. The CR is only 3k, so I would imagine they are producing a big increase in output.

A lot more heat and current draw on their power supply. I wonder if the cooling system is the same and ditto for the power supply. If the same I wonder abour long term reliability and evem bulb life. Just wondering.

It is also well known that the size limitations of the current chassis dictated certain compromises in the design of the Lumis projectors. How many more years are they going to ride the current chassis when they clearly need a bigger horse? A new chassis would cost about $400,000 in tooling costs but given how much this projector costs let alone two stripped down one and the box and filters, isn`t it about time to bite the bullet?

They are available now, though it is brand new so I am not surprised it isn't on their site.

That ain't it then.

From what my dealer tells me, the Uno is similar to the C3X 1080, but it's built on the Lumis chassis. It has no DI and it uses a 260w lamp instead of 280w....2000ANSI instead of 3000; 9,000:1 instead of 35,000:1. Supposedly it still uses DC4 chips. It is $10K less than a Lumis, so that puts it mid-way between the price of an HT3000E and the Lumis.

230watt...not 260... Just as an FYI.

I got the 260w spec from a SIM2 March Newsletter that was on our dealer's counter. Maybe it's a misprint.

Or mine is a misprint...mine specifically says 230watt...

I'll see if I can get to the bottom of it.

Don't want to derail the thread, but are there other new Sim2 projectors available that aren't listed? I understand one or two new Sim2 LED units will be latter this year?
