*solved* NW white XM-L T6 and XP-G R5 do exist.

EDIT: pictures in this post does not show the whole truth. NW XM-L T6 and XP-G R5 exist and always been! Sorry for wasting other peoples time with this. I should have read the text in my own pictures better and and checked the Family Binning and Labeling document properly

I have learned a lot on this forum, but it seems like many people have been misguided by others. I seem to have learned what is wrong by others, and then given the
same false information to others. It also seems several stores spread wrong information too. Which does not make it easier for anybody to get things right.
What im talking about is the cool white (CW) emitters that are down towards 5000k.
They are mostly known as “neutral white” T6 3C and the “neutral white” XP-G R5 3C (5000K), both of which are in fact CW. I say again, NOT neutral! At least that is how I how I see things when looking at datasheets from Cree.

As seen on the datasheets, for XM-L to be NW its has to be T5 or T4 BIN. There is no such thing as a NW T6 according to shown datasheets.
That is not to say that T5 needs to be NW. It can also be CW.

Generally speaking Cree CW xml emitters are 65-CRI, while as NW being 75-CRI. (70/75 for XPG)

Which datasheets are those, I can show you where CREE says NW to XP-G2 R5 at 5000K

NW are typical 70CRI not 75CRI.

Please stick to one thread.

Its the “normal” datasheets. The ones you get when you press “download datasheet here:

http://www.cree.com/led-components-and-modules/products/xlamp/discrete-d...
http://www.cree.com/led-components-and-modules/products/xlamp/discrete-d...

The info about CRI is right below the pictures you see in OP.

For XML2 it says:

Quote:
Typical CRI for Cool White (5000 K – 8300 K CCT) is 65. Typical CRI for Neutral White (3700 K – 5000 K CCT) is 75

For XPG2 its says:

Quote:
Typical CRI for Cool White (5000 K – 8300 K CCT) is 70
Typical CRI for Neutral White (3700 K – 5300 K CCT) is 75.

Look at my screenshot, taken from here:

http://www.cree.com/~/media/Files/Cree/LED%20Components%20and%20Modules/...

You can see the main bulk is 70CRI, and "3" tins are Neutral.

Page 35 and Page 36

The 75CRI typical only for XM-Ls.   T6 "3" are NW.

Strange.. That is the other datasheet i sometimes check for info, but never bothered to read much in. The info I needed have usually been found in the datasheet that is in their main page.

The datasheet i took my XM-L2 screenshots from are the “XM-L2 Data Sheet”. Which is the one you get to when clicking “download data sheet”.
You got yours from the “XM Family Binning & Labeling”.

The general datasheet which is not made to label tints says on page 2:

It is important to note that the base order codes listed here are a subset of the total available order codes for the product family. For more order codes, as well as a complete description of the order-code nomenclature, please consult the XLamp XM-L Family Binning and Labeling document.

ahh..
So that they put T6 under the CW-group and not in the NW-group is more like a simplified generalization.

It's a generalization, even they say if you want more in depth info to look at the datasheets I posted, binning and labeling.

I have made some small changes to OP since thread was made.
Mainly, removed link til LED database and the questions about some specific products in the database over there (sticking to one thread like you asked for).
Minor changes on spelling/wording. Nothing significant.

I should obviously start reading more of the texts in documents.. Silly
Sticking to charts is a bad habit of mine.. Nice to know you know better, so thanks for clarifying! Smile

T6/R5 has nothing to do with CW/NW in itself, they only reflect efficiency. The 3C part directly tells us the tint, and 3C is outdoor white/neutral.

There is a correlation between CCT and efficiency due to the methods used, meaning that neutrals are generally 1 bin behind the latest CW. As T6 and R5 were the highest CW bins available (as was Q5 before that) for a long time we didn’t see and NW T6 or R5s, people often used the heuristic: T6/R5 = CW and T5/R4 = NW.

Now efficiency and top bins have moved on a little we can find T6 and R5 in NW, in fact U2 NW should probably be available in small quanitities too.
