Current ETA for these panels is November. That's not all we're doing so we're pretty busy working on all that, but I don't have a picture yet of the finished panel for various reasons. Hope to very soon though. I'll have a write-up as soon as I can. Thanks.

Got the sample panel back today. The back part with the switches isn't finished yet so all I have at the moment is a front shot.
9 5/8 x 9 5/8 inches. Without the slideout barndoors its about 2 1/4 inches thick. 600 LEDs. 5600K 60 degree beam on this particular model. We will have a limited number of tungsten 3200K units as well. If you wanted a sharper beam, we'd have to use an 8000K LED. Since most weren't excited about 8000K we'll skip that for now at least.
We're working with a company to get some V-mount battery plates to offer as an accessory to attach to the back. Power comes in through a 4 pin XLR on the back. The V-Mount would hook to a special power connection just for the battery plate or you can go in through the 4 pin XLR power input as well with some other kind of battery. There are 5 bank select switches and 1 master switch. Dimmer knob isn't visible in this photo but it will be on the bottom in a special spot where it can't get damaged.
More pictures to come soon...

That rocks. Please also consider an Anton Bauer plate for those of us with HPX cameras as well!

The place I'm looking at has the (as I call it) the 3 stud type also. The thing I need to find out though is what is the difference between the two in terms of mounting to our fixture and does the Anton Bauer have the D tap also--from the pictures I've seen it looks like it does.
We're trying to get samples of both these battery mounts so we can see about carrying them as accessories and accommodating them from a mounting standpoint too of course.
I haven't finished pricing on the panel yet, but lets say it will be a very attractive price for DVXUsers and will include some extras that weren't expected as well.

Yes I wanted a dimmer in this thing from day one for continuous dimming, so we did that, but we also did the bank selects for people that don't like color temperature change that comes with dimming LEDs. Just like on our dimming flos.
Thus, there are two PCBs in this unit. The 10" x 10" LED panel which primarily consists of nothing but LEDs and current limiting and then a dimmer driver board that's about 1.5" x 1.5" in size. The dimmer pot will be mounted in a "valley" in the extrusion we're using on the bottom of the fixture so it can't be damaged. The skinny aluminum dimmer dial sticks out just enough to make it easy to dim, but not easy to find a way to knock it off or break it.
The stand adapter we're using is the same type Yuyao Lishuai uses on their LED panel. A compression locking pivot type with baby adapter built in thats mounted to the bottom of the fixture

The question as to how much will be answered very soon once I know pricing on all the various extras we're including and how much the options/accessories like the battery plate will be. DVXUsers will be able to get it for significantly less than the Lishuai 500 panel from Flolights--as a teaser.
The question about comparison to tungsten fixture is that its roughly equivalent to a 600w fresnel. If you compare by light meter readings that is. Lumen output, as we've discussed before is weaker but where you win with 5mm round LEDs is their ability to super concentrate most of their light out the top thanks to the super efficient acrylic lens. Not hardly any wasted light energy around the sides as with a normal bulb and therefore no need for a reflector. Of course, you can't really compare such a fixture one to one with a tungsten fresnel because the LED fixture will cast multiple shadows. Why? Because it is a bunch of tiny point light sources all creating one large source. The reason a tungsten fresnel doesn't create but one shadow is that there's a single concentrated larger point light source with a great fresnel type lens. So what you get with such an LED fixture is kind of somewhere in between a hard and soft light. Good throw, a bit soft but not as soft as a flo or diffused tungsten of course.

This looks pretty damn good.
The rosco led sells a 12x12 inch for $146.92:

But without casing and probably less output.
Do you see any change in color-diable leds, Richard?

Yes, you can't really compare the two. Not even close to same output and really different uses and yes, we've got a great fixture around it to make it durable and with barndoors. Remember that the rosco's are edge lit and thus only have in effect 4 rows of LEDs--one row along each of the 4 edges. So no where near 600 LEDs. That kind of panel definitely has some use but thats not the one we're designing here. An edge lit panel could be another interesting product for the future. We know where we can get a 24 x 24 inch edge lit panel. Put a frame around it and add a lollipop or yoke and you've got a pretty broad source, but not huge output though, even with that model.
When you say "color-diable leds" I assume you mean RGB types which will let you put in whatever color you want to output? I have looked at those but they seem so weak compared to single color LEDs. You effectively divide the output capabilities by three in most cases when you use an LED like that so you're not getting what you could.
On battery mounts. I have the samples back and am posting pictures here.
First the V-Mount type:
Then the AB Mount type:
And a picture of the back of both:
They both have the standard mounting holes so they can go on whatever camcorder. We'd just provide 4 screw mounts on the back panel of the LED fixture and then we need to see if we want to use the D-Tap type connector to connect to our 4 pin XLR or provide a screw terminal input to the back of the fixture thats in parallel with the 4 pin XLR 12v input.
I'm not crazy about screw terminals because this is polarized +12 and GND and that leaves it open to getting it wrong even if its marked. Much better to have a keyed connector of some kind but we don't want that hanging out of the back of the fixture either (as not everyone will use the battery option) so that all has to be done in the best way possible so it's child's play to put it together whenever you decide you need the option.

There are two ways to do that--where you have 3200K and 5600K in the same panel.
1). The way I discussed quite some time ago to have alternating columns or rows of 3200K and 5600K both on their own dimmer is a kind of brute force method. Then you could either have all 3200K or 5600K or mix colors in between. The drawback is that with such a panel, assuming 600 total LEDs, you've got 300 of one color and 300 of the other. Leaving one color entirely off means that the other half that could have been contributing output is off. If you never use 3200K, then half the panel is wasted or vice verse. Most didn't like the idea so we skipped it.
2). Use RGB LEDs like Zylight and have a microprocessor type control which can custom mix the colors to get whatever color you may be looking for from solid colors like red, green, blue, etc. to shades of white (5600K or 3200K). In theory its great. But, thats a big project to do that controller, and also since RGB LEDs aren't as efficient, you don't get all the output you might like.

Yes I think we're ready now and have all the information. So here's what the pricing will be:
This panel would normally sell for $479 on our site but for all those early adopter DVXUsers and RedUsers, we will be selling for $379. This includes the panel, angle adjustment stand adapter, removable barndoors (slide in and out of accessory holder like our studio model flos), 12 VDC Power supply and as if all that wasn't enough, we'll be throwing in a free nylon padded carrying case for the fixture and accessories for DVXUsers and RedUsers.
The battery plates, which were already shown in a previous posting in this thread, will be $125 normally but will be on sale for $99. They will be easy to install by the customer and will be available in the AB or V mount types. So, that means that for under the price of the Lishaui 500 panel you can have more light output, a carrying case, easily removable barndoors AND a battery mount.
One cool feature of the power supply is an attached carabiner (like the ballast of the CDM 150) to allow it to hang off the knobs on a stand rather than gathering dust and lint on the floor. The cable from power supply to fixture is 6 feet long and the cable from power supply to wall is 15 feet long.
On the battery mount accessories, I would add that we won't have a huge stock of those so I would order those early if you're interested in that accessory. I have no idea what to expect on that yet and which will be more popular--AB or V so we just took a guestimate on stocking for those.
As of right now, I think availability is early December. I'll post more as I have more information.
