I want to mod some drop-in and some EDC and i need Nichia 219, XML2 and XPG2 on 16mm round board. Anyone knows where to get them?
Thanks
If you have soldering iron, you can reflow them yourself, they are ultra-easy to do (I did 4 triple-LED stars yesterday which is 3x more hard with no issues)…
THAT being said, check what IlluminationSupply has in offer…
IS ships to southern Europe for reasonable price (was better before USPS decided to up their international prices)…
It is a pain to get the right leds on 16mm boards.
Intl-outdoor.com had some XP-G2's and XM-L2's on 16mm boards but were sold out soon (I think they just wanted to be the first to sell them for promotional reasons and don't care for keeping them in stock), cnqualitygoods.com has some very cool white XM-L2's on 16mm boards at the moment, and XP-G2 in cool and 3C also on 16mm (not sold out yet I believe), Illuminationsupply.com has both XM-L2, XP-G2 and Nichia219's on too thick 10mm, on 20mm, and bare but they don't do 16mm boards for some reason. I ended up reflowing myself as well (it is easy to get bare 16mm boards, dx has them and Ill.supply also)
Don't like Cutter for their shipping fees, leddna and led-tech have a very limited (cool) selection.
Cnqualitygoods is the best bet at the moment I guess
Thanks everyone for the advices. I follow the suggestion of djozz and i found XPG2 and XML2 on 16mm board… The problem is Nichia Led… I think i will buy mcpcb, bare emitter and try to reflow.
Thanks again
The XP-G2 3C from cnqualitygoods cost 5$, so decent price for that tint. But the text does not say anything about bin. Description says: “402 lumens at max current 1.5A”
That makes me think it is not better than a GP-G2 Q5 BIN. Which is not impressive. Id rather get a decent bin XP-G instead.
I dont see the point of buying XM-L2 when its T6 and cool white. You could just buy XM-L U3 from fasttech at a lower price.
I guess the reason why cnqualitygoods still have them in stock is due to low bins, which does not make them better than 1.gen XP-G and XM-Ls in my eyes…
I have not done your calculation, it is too bad if the bins are poor at cnqg. But I'd still go for the XP-G2 because they can be driven harder than the old XP-G, and throw a bit better.
I use this thread for checking out bins.
Here are the different Bins at highest rated current
XP-G
Bin 1500mA
R2 380-406
R3 406-433
R4 433-463
R5 463-493
S2 493-520
S3 520-547
S4 547-573
XP-G2
Bin 1500mA
Q4 373-399
Q5 399-425
R2 425-454
R3 454-485
R4 485-518
R5 518-558
XM-L
Bin 3000mA
T2 650-715
T3 715-780
T4 780-845
T5 845-910
T6 910-975
U2 975-1040
U3 1040-1105
XM-L2
Bin 3000mA
S4 612-641
S5 641-679
S6 679-746
T2 746-820
T3 820-895
T4 895-970
T5 970-1044
T6 1044-1119
U2 1119-1193
Using your numbers: given that XP-G2 is binned at 85 deg Celsius which means it is 20 brighter at 25 deg, a Q5 XP-G2 more or less corresponds to a R5 bin in the old XP-G.

Scaru's numbers for the XPG2* are adjusted by 13%** to make it easier to compare binning for the XPG2 to the XPG as well as other emitters binned at 25C. They are not what Cree lists in their spec sheets.
I'm pretty sure that CNQ used Cree's specs, and not Scaru's. So, by Cree's specs, an XPG2 that produces 402 lumens min at 1.5A would be R3 brightness bin.
If CNQ listed the correct specs on its page, its XPG2 3C should be R3 emitters. However, I doubt that this is the case. CNQ also lists XPG2 1A emitters with 402lm @ 1.5A listed as the output which would also make them R3 emitters, and I'm not sure if Cree even makes XPG2 1A in R3 bin (do they?). To make things even more suspect, CNQ uses the same photo for both listings, and the photo is of XPG2 2B R5 emitters.
I think the only safe thing to assume is that the info on CNQ's listing might not represent what they have in stock.
*original reference - Flashligtwiki article
**I'm not sure why Flashlightwiki used 13%.
Yep, you're right there. I've been thinking about adjusting it to what is in the datasheet to make it easier for cases like this. Or I could just add both. What do you think?
I think your post is fine as is. Your notes explain the 13%* thing and reference the Flashlightwiki article. I think most people understand the difference.
It's not your fault if some of us just scan the numbers instead of actually reading the notes in the post.
*I get it now. The 13% difference comes from Cree's datasheet. The "flux characteristics" chart on page 2 of the XPG2 datasheet lists the flux at 350mA at both 85C and 25C, and the difference is 13%.
Ok, ok, I plead guilty in not reading all notes… 
I can't blame you in the least, that thing is way to damn long. ;)
Does anyone notice that the photo says R5 2B, which at CNQ was never sold as fas as I know.
