CPF has a thread on it and Eagletac has a light out already with the XHP50 in it. Limited edition, which means they got samples from Cree before anyone else.
5x5 footprint and 7x7 footprint. Even with 4 dies, a 5x5 footprint should make a light that could be? a fair thrower and replace XM-L2. 7x7 would replace MT-G2.
I want some of these.
Especially the 12V version of XHP70 in 5000K, 80+ CRI, 3-step in N2 bin. Or the 5000K, 90+ CRI, 3-step in K2... Or the....
*drool....
None of these emitters will replace the XM-L2. Too high voltage, not enough throw for most lights. Time will tell how they compare to an MT-G2.
I would guesssssss..... that the dome will help eliminate the normal black cross shadow, that you would see in a 4 die setup and the dies look like they might be tighter to each other, but that might just be the photos. I would think in a bigger deep reflector, that has the bottom third/half in an OP finish and the rest SMO, it might just throw pretty good in the 5x5 format.
I asked Cree to let me have some samples, but I won't hold my breath.
I don't expect an answer since I don't have any pull like the flashlight makers do.
4x XPG2’s squished up together?
No, they did more than just vary on existing designs, i.e. there's no bond wires in sight (on the limited images at least)
I like the pricing of the XHP50, $6.31 at Mouser.
might be glad i’ve held off on upgrading that lowe’s lux pro.
so all that’s left is to figure out how to drive the XHP70?
i’m not averse to a driverless DD option, if you have a suggestion.
..and wait for a board that it fits on, 7x7mm is between the XM-L and MT-G footprint.
I wonder what if we drive the XHP70 LED at 9 A like we do to the MT-G2 J) how much lumens we can get ?
If it behaves well up to 9A, and on a copper board, my rough extrapolation leads to about 6500 lumen.
Hey, there's 5000K 90CRI versions in the datasheets of the XHP50/70 ! :-)
That is like,, old news...
Just kidding.. Its awesome. These emitters will probably be used in many lights next year. I already have some plans.
2.25 hours old news, I see it now. note to self: read RaceR's posts more carefully :-)
" At its maximum current, the XHP70 LED delivers twice the light output of the industry’s brightest single-die LED, the XLamp MK-R LED, at a similar lumens per watt and without increasing the package footprint"
Lie nr1:mk-r isn't single die led
Lie nr2:even if mk-r were single-die,luminus cbt-140 is still brighter
Typical CREE marketing.
Anyway,it looks like xhp50 is 4x XP-G2 and xhp70 is 4x XM-L2 die.
Hopefully the beam pattern isn’t too bad. 
Hopefully the new single die LED 5x5 , 7x7 will coming out soon 
So, the XHP50 6 Volt will go right on an XM-L star, what will the XHP70 fit?
and where the hell do I get some?
just give me some XHP70 
and i will do what ever it needs DIRECT TO PILL
Hank Wang SAVE US i want to find it on your shop by tomorrow J)
I smell changing in the wind
It looks like the 6 Volt version will work on an XM-L star. But there are tiny differences. On top of that (as you probably know) XHP50 and XHP70 LED`s can also be configured to12 volt depending on their connection/star.
Mouser for those who are lucky enough to have cheap shipping and are happy with their current selection. Im waiting for Hank to stock these. Preferably with some really high CRI.
Question is, why weren't these in stock yesterday along with suitable Noctigons??! Getting impatient here.. :p
The XHP70 on Mouser says it is 1590lm and price for one is $16.85 plus shipping. I think it would be wise to wait for a better deal.
1590lm @ 1050mA. The emitter (in 12V configuration, which is what its binned at) is (officially) capable of 2400mA. So 1590lm is far from what its capable off. That deal will give you more output compared to an MT-G2.
The emitter Mouser have in stock is not the top bin though. Problem with Mouser is that they are not very specific on tints.
These are floody emitters. Give me NW, high CRI and then top bin for that combination. :) please...
