BLF LED Database - Collaboration Spreadsheet - Share latest news about where to buy LEDs

I’m guessing a dedomed WW emitter looks a little like a campfire in tint :smiley:
It’s interesting how that 5C1 can be so two spots to the right of 5B1, on the same line, and yet only be 75CRI. :~
I have two of those 7D3 90+CRI siting on my workbench… just itching to get onto a star :slight_smile:
Where did you find 8B4? That’s almost an incandescent :wink:

Its T5, the 80+ CRI emitters are T4 at best. If you see in the CREE spreadsheets, often when you go higher in CRI you go down on BIN. So its not that surprising.
Sometimes the trick is to find the nice emitters that are top bin, and the highest CRI for that emitter. Many stores seems to get this, but there are a few emitters out there that is not the top-stuff.
This T2 7C1 as an example.
Im pretty sure that in that tint you could get T3 and 80+ CRI, but that emitter is “only” 80 CRI-typical and T2.

Another example is the T3 6A1 from intl-outdoor. Im not a huge fan, because its quite rosy-red-ish (IMO, I have one) And its “only” T3. Why do I say only?
Because I have a T4 6A3 incoming. Higher bin, hopefully not much “rosy looking”… Its not available from the Aliexpress seller anymore though. When that is said, Intl-outdoor does not sell it bare either anymore but with the X3.

Another example with CRI, 5B1 with 80+ CRI is T4 BIN (from intl-outdoor)
leddna sell 5B in T5 bin, but then it has to be 75-CRI. (Its not added in the database, I don’t add everything I see, especially if the information is not complete or the emitter is really cheap. 5B what?? I dont want a super yellow 5B…)

The 8B4 came from this seller along with several of the other WW emitters I have incoming. Ill add them if they seem like the real deal, which I have a feeling they are. Im curious how it will be, I have never had anything that warm… :slight_smile: I have a feeling it will be way too much, but you never know.

When it comes to 7D3 90+CRI, you have to be good to tell the difference between that and 80+ CRI. If you like the tint, then you will like it, if not, the 90+ CRI will not do wonders based on my experience. Such emitters should be nice tint mixers in various multi-emitter lights with low/mediocre CRI…

Have the T4 5D2’s already sold out? Can’t find them on the website.

It’s a bummer that Aliexpress vendor was banned. He was giving a great BLF discount. I see my order of xml U2 3C’s are sitting in NY right now. I also have some xml2 T5 5B1’s on the way from him.

Yupp, seems like that…

Just because he was banned does not mean its not illegal to talk about him, this aint CPF.
But since he is/or was banned (he have a user account with convoy something in the name), im a bit cautious recommending him. But I have not heard of any complaints from buyers yet. If the stuff I get seems to be as advertised, I will add the emitters to the database. His selection is quite good, and with a 30% discount, so are his prices. I did not have to buy 5 of each, he fixed the price/quantity before I paid. He answered real fast too.

From an emitter perspective, based on first impression his emitter selection seems to be way more serious than several stores who are not banned, or even recommended.

Ehm… XML U2 3Cs???

Yes, I hadn’t heard of XML U2 3C’s either. He claimed they were legit in the thread that I can no longer find. When I get them I will do my best to determine if they are really 3C.

*EDIT: I’m receiving a light meter today and I have some 3” PVC tubing and elbows (integrated tube). I can try to measure difference between U2 2C’s and U2 3C’s. Assuming everything else is equal, they should measure about the same, right?

EDIT2: USPS email says that they left a notice. That means I have to sign for it. So it will be a couple more days before I get the meter.*

You could assume so, but a U2 could technically be as bad as a the best T6. Im generally skeptical to emitters that are not in the Cree datasheet unless its XM-L U3.
Never heard of U2 3C, and its not listed either, but maybe Cree managed to come up with one, kinda like U3.
Please share your results, im curious, although I would rather buy XM-L2 T6 3C mounted on Noctigion with the prices Hank currently have if I was after 3C tint. Im guessing the last ones mounted on 16mm stars will not last long. XM-L2 T6 3C on 20mm Noctigion is already sold out…

CNQ have XM-L T6 3C for 3,5$ (without shipping) on clean sale. add Noctigon and its 5,35. Id rather pay about 1+$ extra and get XM-L2.

Thank you. Will do. I prefer xml’s in single cell and parallel single cell lights. Just easier to drive at higher currents with 1S voltage.

Thanks for explaining that, it helps. I’m looking forward to hear what you say about those emitters. I hope that seller turns out to be legit, there are good options there.
I noticed that the pics of the labels on some of those emitters are from sample packs. That concerns me a little, since it doesn’t prove much about the actual parts you would be getting from the reel. Not that a reel label picture is definitive, but using a sample label in it’s place doesn’t instil much confidence.

Added the following emitters:

NOCTIGON XM20 MCPCB & CREE XM-L2 T6 3A LED 6.49$ (minimum 3)
NOCTIGON XM16 MCPCB & CREE XM-L2 T6 3A LED 6.39$ (minimum 3)
NOCTIGON XM16 MCPCB & CREE XM-L2 T5 4C LED 6.98$

Hi, are you talking about XML U2 2C or XML2 U2 2C? Anyone know where I can get XML2 U2 2C?

(I'm also looking for some XML2 U2 0A if anyone knows where I can find those)

Thnx

XML U2 2C

leddna has XML2 U2 0D on sinkpads. $8 each if you buy two and they have a %15 discount blf15.

I figure the 0D should dedome well since the 1C gets a little too yellow/green.

They also have XML2 T6 4C listed, I ordered on to compare to my T5 4C and XML T6 4C. 4C is my favorite so far.

Thanx bdiddle, that is exactly why I want a 0A/0D and not 1A/1C.

Now only to find some XML2 2C's

You can get XM-L2 U2 1A for $5.92 on Noctigon if you buy 3 (even cheaper for more). 1A is slightly cooler than 1C.

Yeah I have some of the IO U2 1A’s coming, but I doubt I’ll be happy with the dedome. 1C just looks really ugly to me. I have one now dedomed and I can’t find a light I like it in. I keep pulling it out for intact dome emitters……

Ill add the XML2 U2 0D from LEDdna later. I knew thay had them on pre-order some time back, nice too know of a source for these.

I just noticed intl-outdoor have added XM-L2 T6 in 4C tint on regular mcpcbs (12/14) and on copper (16/20). They had these before too, but not that many options, and now they are a bit cheaper. :slight_smile:
NEW products.

Hank needs to stop with these nice emitters. Seriously. I just got some more T4 5B1’s, T5 4C’s, and am waiting on some T4 5D2’s and U2 1C’s.

And now T6 4C’s, which I think are my favorite tint. Now if we have T6 4C’s, where are the U2 3C/2C, or U3?

There have been so many new emitters lately its almost hard to choose which to buy! :stuck_out_tongue: And thats a good thing…
I used to buy flashlights, then I had to find emitters for them…
Now its more like… “oh, I want to try that emitter, now I need to find a flashlight for it.” :smiley:

!!HUGE XM-L2 UPDATE!!!

All prices have been updated! (except the ones that have the note “NO” to free shipping)
Lots of dead links have been deleted!
A few emitters have been deleted since they serve no purpose due to price!
Several new emitters/links have been added!
Lots of comments have been edited. Intl-outdoor recently had minimum order of 3 quite recently. Now a bunch of those are available for about the same price without minimum quantity.

A few things that can be found:
A bunch of emitters that are copper mounted!
A bunch of emitters in the 5300K range and lower. Not only 3C, but 3A, 3B and lots of various stuff.
XM-L2 T6 1B for as low as 4.09. Or 3,66$ a piece if 5+ are bought.
Or what about XM-L2 U2 1C for as low as 4.97$ (12/14/16/20mm mcpcb). Down towards 3,95$ if 10+ are bought! Copper mounted only cost a little extra.

If anyone wants to *help *updating the XP-G2 sheet and adding emitters, that would be awesome. As an example I see LEDDNA sell NW XP-G2s as low as 3,45$. IF the “BLF15” coupon code works on those then its only 2,9$ for a NW XP-G2 (R3 5B)!! Several emitters out there that have not been added, and lots of prices that have changed.
