Has anyone received one of these yet? Has anyone seen a spectral chart of one of these new 2014 models? I'm dying to know more about these new panels!

I heard that they would be putting them up on their website over 3 weeks ago. That chart is all I am waiting for before I pull the trigger on a few of these. Call me crazy but i can't/won't bring myself to order without seeing this. Why would A51 put these up for preorder without releasing this info?

Yeah I know how that goes. Very understandable to wait and order until the spectral charts are available. Good luck!

Yup^^^ exactly ...............should perform excellently like Captain's grows with the xt-e bulbs. Now we just need Bin#'s from EH
My only concern is the small % of 660nm in the 3700k spec............I think CM did use a "red" booster in his last grow??

I know there is more than one way to make a white light source end up at 3700k. I am simply saying that I (as a consumer) would like more info on the product I am interested in purchasing. I (the consumer) should not have to go chasing the info off of cree data sheets. I don't mean to offend anyone, just looking for the info "from the horses mouth" before I drop my hard earned cash on their product. No disrespect ment to anyone especially not you Guod or Psuagro, I dearly admire both of your work.
Regards.

Do you guys think that the spectrum will be exactly like the orange line in this graph?Eraserhead

The A51 site is updated with all the spectrum and Umole charts.

Hmmm, the A51 spectral analysis of their XGS-190 shows a more broad spectrum than the spectral graph I found for the coinciding diodes in the Cree Datasheets.. Can someone explain this to my feeble mind? 
View attachment 2898828
Am I correct to assume that these diodes are driven harder in the A51 panel than the diodes Cree used at the time of their spectral analysis?

Yes they are, except I got mine from Digikey.
The chart you have shows just 3 of the many kelvins available, 1 from each color temp family: warm, neutral and cool.
That is why I've been mia for the last 3 months. Glad it's over, that was a lot of work.Sweeet, are these the LED's in the new panel??
http://ca.mouser.com/ProductDetail/Cree-Inc/XTEAWT-02-0000-00000BFF6/?qs=ygRr/tkhtetRvt2BXefEAA==
Generally, white Cree LEDs are available in 250k increments starting at around 2200k and ending at 8000k-something..... Also, the blue LED chip from one Kelvin to the next is identical as well as the phosphor blend. What changes from each 250k increment, the ratio from 400-500nm and 500-750nm changes.^^^^ Somebody has been working hard......!

Thank you Mr. Eraserhead! You have been very kind and patient with a led noob like me. Thanks to everyone who tried to help me out with my questions!
Peace!

Prompt and transparent as usual! Thanks, man!
So.... If I'm in the market for a new light, is this the one to get? I was about to pull the trigger on a Blackstar Chrome 405w, but then I found this light for almost $100 less and now its got me thinking.... What's the better route? I'm in a 5x5 tent with a 4x4 table with two - 1st gen "450w" (300w) panels.

Yep. I promote them in every thread I cross where someone is asking about leds.
Even though you find me in a lot of DIY threads, I have neither the equipment to build nor the analyzing equipment, should I have a problem.
I have cobbled together a combination of commercial led tubes + globes. Pretty decent results, but costs more than one realizes to get a decent umol/m^

I have been waiting (not so) patiently for this panel since the talk of a new panel started. These are the best value there is if you can't DIY one..
