Sitting in a container ship somewhere? Could be a dozen good reasons especially lately.
Just got an email from Mouser informing me that my order for XHP50.3 HI 4500K 90+CRI is being pushed to January.
XHP50.3 HI is in stock at KD. Link is here "http://kaidomain.com/Cree-XHP50_3-HI-White-6500K-LED-Emitter It will be interesting to compare with SFT40.
Linked corrected, and donāt forget that the XHP50.3 HI in the link is the 6v/12v version as opposed to 3v for the SFT40 but otherwise yes, it will be good to see how the XHP50.3 HI performs the way we use them 
The Cree XLamp XHP50.3 HD 6500k is also available. Not really my color temp. I guess I will keep on waiting for the xhp70.3 warm white to become available.

Mouser added several XHP50.3 HD on order, availability announced for February : https://www.mouser.fr/c/optoelectronics/led-lighting/led-emitters/high-power-leds-white/?q=xhp50d&normallystocked=y
I have noticed that 3V version is only 6200K. I was hoping to have choice of 5000K version but seem to be only available with special order like 50.2.
Has anyone found an in-stock supply of XHP35.2 HI in flux bins greater than D4? I hope to find E2 flux bins or greater in 5000-6500K to reflow into my stock GT. Crees data sheets appear to be dated and they are notorious for not listing all available variations. Iāll probably settle for a D4 if nothing turns up. Mouser has plenty in stock and they are easy to deal with.
Still no listings showing for XHP70D-H0 variations (XHP70.3 HI). Id love to try one in a GT with a TA driver, assuming high flux bins once available. Creeās data sheet looks promising.
Iāll probably cross post this in a few other threads to see if anything turns upā¦
XHP50.3 HI 4500K 90cri are in stock at Mouser now:
Looking at the data sheet for the XHP50.3, if Iām reading it right, the 3V only comes in 7000K and 6200K in HD and not HI at all.
Is that right?
Thanks for the heads up. I havenāt bought any LEDs for a long time but I think Iāll grab me a few of these.
Man does Mouser make searching for LEDs a painā¦ if you select XHP50D-HI series, which itās supposed to belong to according to Mouser, and check āin stockā flag you get 0 search results. In the Cree datasheet they are clearly called XHP50.3 yet Mouser want to use some other series name which in turn doesnāt show this LED that they themselves have labeled as belonging to.
Indeed, my order that was in backorder just shipped, letās hope they donāt have a trash tint.
Thanks. Ordered.
I put a XHP50.3 HD 4000K 90CRI from Digikey into my Skilhunt H300. My Opple says its a bit green, but thankfully my color-deficient eyes canāt tell :disappointed:
Gchart, that pic looks like a gen2, no? I thought dot three versions had a white silicone pour around the die.
Good eye. That picture was taken before the emitter swap. It was more of a āhurray, I got it openā¦ and hereās what it looks likeā picture. I have updated my post to note this.
The new LED does have the white around the die and is not covered in a phosphor pour.
XHP70.3 HI looks interesting.
XHP70.3 HIs have been listed at Mouser, several of them have a MOQ of 1 (none 90CRI 
), no lead time info.

The XHP70.3 Hi looks like perfect LED for ZL SC700d

I didnāt test higher because itās a quick test without heatsink, anyway the tint is sunlike (0.0033), or slightly greener at lower current. Disappointing that itās not closer to the BBL
The beam looks quite good even with SMO reflectors.
At 0.1A with KR1 SMO reflector :

Corona : CCT = 4191K (Duv 0.0067)
spill : CCT = 4383K (Duv 0.0032)
