I just went to cutter's page to try and buy some xhp50.3 HI, 5000k. BUt they all say (on mcpcb's) configured to either 6v or 12v.. can they be used on a 3volt mcpcb? My guy says no, but i saw the post and data sheet info that says can be configured to either 3/6/12volt.
I'd appreciate any help, I don't want to buy a 6/12v only unless I know it's that while I'm buying it. I'm so confused.. . I prefer 3v regardless of tint and cri, I just want to try the HI XHP.3 emitter out.
I spent some time searching. It looks like the 3v isn’t out or just not for sale yet.
What I understand the hi version does not come in 3V configuration, just the hd version in cool white comes in 3V. 6V/12V is the same led with a diffferent PCB, but 3V requires a different led build.
Thank you both! Looks like it's either waiting time or maybe not at all.. I will have to do some Convoy builds to try out those xhp50 HI's..
to reconfirm
50.3 HI DOES NOT COME IN 3V
only HD will be 3V
Cheers
Well that’s sucks…Hopefully we’ll see it in lights like the MF01S. I really want something like an X50 but cheaper.
yea, that is a friggen fail if I ever heard of one.. I know the flashlight industry is peanuts to a mfg like Cree, but that just sucks all the way around. I mean there are drivers made and that will be made, but it's another workaround and incompatibility issue..
anyway, yea a 2s2p massive light would be cool, with 3k or 5K tint :))
although- now I'm thinking- I can put one of these setup for 12v in a K1 (xhp35 hi model). In fact, I will be doing that. Once they are available more locally or with less shipping costs
I am so confused by that website.. I hate being stupid lol. I will eventually order some 50.3 in 5K & 3k. Anyone who wants someone to "go in" with them, I will. I'm in the US
Just dropped by to tell you that Kaidomain is listing an XHP50.3 HI for pre-order. The only additional information listed is “Cree XHP50.3 HI J4 3A Neutral White 5000K”. Click/tap here for the official Cree XHP50.3 datasheet. High CRI options galore.
Nice, hope some good CRI90+ variants arrive soon at the usual retail channels. 
Can’t wait!!
They’re now showing several different XHP50.3 and two different XHP70.3 in stock and can ship immediately. Anyone order some yet?
The thermal resistance of the 50.3 is much improved over the 50.2, .4°C/W vs 1.2°C/W.
Nice ! 4500K, 90 CRI, 6V/12V
We should take bets on what the duv of this bin will be
And they’re going to stock it in December. I already know what I’d put it in.
It’s domeless, so at least it will be consistent
oh, quite interesting, flat XHP50.3
Thanks for sharing this information, thefreeman and the rest of you. I made my own, specific search for CRI90+ HI emitters at Mouser EU.
Wellp, out of 39 entries only the H2-45G (3-step 4500K) is available in small quantities. Other interesting easywhite parts are listed, like this F4-27H (F4 bin, 2-step 2700K), or this G2-27H (G2 bin, 2-step 2700K), these are “incandescent” while as close to the black body locus as Cree “bins” them. The second page of the above search contains many 2-step emitters.
I'd love to get a few “warm” HI emitters, 3500K or 4000K tops…
