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

Found something funny about LEDDNA. I think they might have changed the tints they carry but are just redirecting links for the original tints to their new tints.

Try this http://www.leddna.com/cree-xpgbwt-xpg2-xp-g2-r5-3c-neutral-white-led/
xpg2 R5 3C redirects to R3 5B
xpg2 R3 7D redirects to 7C
xpg2 R5 1C redirects to 1A
They don’t seem to carry the tints listed in the spreadsheet anymore.

I haven’t changed any tints / bins or links in the spreadsheet, thought I should mention it first.

:slight_smile: :beer:

Stores seem to do things in different ways. Changing bin/tints in the same links are not unusual for some.

Was it you who updated some prices and added comments? :slight_smile:
For people who contribute, please fix everything on a particular emitter if updating. tint/bin/price/…etc… Add your name behind the person who added the emitter and fix the date when it was last updated. :slight_smile:
Ill start doing some now…

XP-G2 update

All emitters with free/not expensive shipping are now updated except the ones from LCK-LED. I was not able to access their site at the moment.

One cheapo emitter I noticed.
XP-G2 R5 1D from Fancyflashlights are only 2,9$ now!

Great option for those of use who like to de-dome those emitters. Its a nice option to the cheapo XP-G2s from Fasttech.

Thanks to Helios(?), for doing a little helping too before I was done. :slight_smile:

I’ve been delaying reporting on receipts from Simon on Aliexpress because I haven’t performed any testing on the emitters. I’ve been meaning to set up an integrating tube and to also subjectively rate the tint, but I have too many irons in the fire. I doubt I will get around to it anytime soon. What I can report is that I received 2 orders so far. Both placed at different times and both arrived fast and very well packed (in anti-static, bubble, and boxed). The color of the phosphor’s appear to to match the descriptions. What I have received:

  • XML2 T5 5B1
    The color of the phosphor appears to be identical to my XML2 T4 5B1 under incandescent and under UV lighting. I know these will not be 80cri min, but I’m hoping they are not far from it.
  • XML U2 3C
    Comparing these to some XML U2 2C from Fasttech, they are slightly deeper tinted (as expected) under incandescent lighting. Under UV light, the contrast is much bigger. The 2C’s are more yellow. The 3C’s are more orange. The contrast seems a bit too big, but I have no real experience in such matters. R86 expressed concern about this bin/tint not being in the datasheets. Since I see no evidence to the contrary and a picture of the package labeling from Cree is posted, I accept Simon’s representation as truthful.

EDIT: Fixed typos

EDIT2: My XML2 T4 5A3’s arrived today. Same as the above, arrived quick and very well packed. Color of phosphor is very similar to T5 5B1 above.

I have a feeling you will like the 5A3s. :)

Thanks for sharing your experience with these emitters based on what you have seen.

Im still waiting for my package! It left china about 2,5 weeks ago, and no sign (Im not blaming the seller). I have never had a registered package take more than 30 days or go missing. Hopefully this one will not be the exception. I have a few lights waiting for those emitters now. :)

Damn RaceR86, your fast. First thing I do after seeing new xml2 on fasttech is bring up the spreadsheet. Maybe I’ll beat you this time… Nope, see you adding them as I watch. :ghost:
:beer:

:bigsmile:

:beer:

Should a post be made here following edits to the spreadsheet? Just new product additions or would you like to keep track of any edits?

Corrected an error I noticed. The ledna XP-G2 R3 5B leds were listed as 5000k, changed it to 4400k 4200k.

edit
Hmm, I’m seeing illumination supply XP-G2 R5 3D 20mm star listed twice@$7.25 and once@$5.5
Guessing that is suppose to be 20mm $7.25, 10mm $7 and Bare $5.50. Correcting.

Spreadsheet wheres waldo game. :party:

If there is a minor mistake, just do the edit. I don't see the point of announcing minor changes, or error fixing. But if you feel that the change is important, feel free to post about it. I have done a bunch of minor fixes, and sometimes added/changed several products, deleted dead links etc.. I don't bother notifying about minor changes to emitters that have been added.

If you update a line/emitter completely, just fix the update date, and add your name too it. I don't think there is a need to bump the thread for every minor update. But if the updated emitter fell 2$ in price, then it might be valuable information to some and then be worth mentioning. This is just my opinion though..

The most important thing is that people can visit this thread and see the more important things that have been added without having to browse the spreadsheet on a weekly/monthly basis just to see what have been updated. LED related talk/questions is no issue either..

I started this thread, and the database. I hope that in a year I was just the person that got the ball rolling and that several people contribute. Its nice seeing many other names in the spreadsheet than my own. :) Feel free to look for errors and fix them, im sure Ive done several slip ups. And sometimes, stuff are wrong simply because stores update the emitter.

The kelvin estimates is probably slightly off too at times, but those can be discussed, and sometimes even the stores selling the emitters does not seem to always state the same range either.

The most important thing with the database is that people should be able to find the emitter/tint/mcpcb combo they desire, preferably at the best prices out there without having to browse through all the various stores in order to find what they are searching for.

I also hope that to many people this database works as an eye opener to what is out there. Maybe I did not look much, but even in the beginning of 2013, it seemed like CW (normally 6500K A1/1C) was the most default option by everyone, many people had discovered NW, but most just talked about the 3C. And if people talk about WW, then it was mostly a 3000K emitter. There was a huge gap between the 3000-5000K range. And there was little focus on tint color (not temperature) in general. If you wanted decent CRI, then you had to buy the typical high CRI Nichia 219 (nothing wrong with that). I have started to notice more an more people exploring different stuff lately, and I don't hear much complains from people who tries new things. :) Rather the opposite, people who start disliking what they used to like, or people who develop new preferences.

Testing out various emitters and finding out what you like in what circumstance and in what type of light adds a new dimension to the hobby, some may not be into that. But no matter what people are into, the database should be useful as long as they are shopping for new emitters.

The XM-L2 T3 6A1 80 CRI minimum are now in stock at intl-outdoor again, copper mounted. Added to the spreadsheet. They are WW, but the not super warm. They are probably the least yellow and most "rosy" emitters in the database. Its the same as the ones being sold in the WW Xin X3.

6,86-6,89$

Thanks to anonymous for adding emitters from FT.

When that is said, no need that add emitters that have already been added. Ill delete all the emitters that are double.

As mentioned in OP, there is a sort feature. Sometimes all emitters are not shown. I guess the anonymous user did not see all the emitters that were added. There is a total of 100+ XM-L2s.

I have added the following emitters btw. All available in 12/14/16/20/25mm mcpcb.

Ill get back to my experience with this seller, but I consider him good, and so does others it seems. When that is said he used to have various other emitters about a month ago, some good stuff that he no longer have. Currently he have a lot of emitters that FT sells too, and FT are cheaper. The three emitters above seem to be unique for his store at the moment, so that is why I did not bother adding more than those.


Will we ever see XML2 2C? I'm sure I'm not the only one who finds 1C's too blue, but 3C's too yellow If I shine a 1C and 3C on the same spot (presumably 2C then :) ), that makes the perfect color to me. Why is no one selling XML2 in those colors :(

The 2C might arrive, tomorrow, or next year.

Have you tired the 3A? Slighty cooler and less yellow compared to the 3C.

If you neither like 1C or 3C you may not like 2C either, have you tried a 2B tint ?

Do you know of a place selling XM-L2 2B?

Nope, but there's XP-G2 R5 2V available.

I have both 2B and 2C XM-L1 and they extremely close.

RaceR86 suggested I place this chart here. I’m glad he did as I had not spotted this thread. I realize there are probably other sources and some more options out there, I just placed the ones that I was looking at on there. I’d be happy to keep it updated if anyone sends me some other viable (International) sources. As I am not in the USA the sources there are not on my radar due to the high shipping costs that USPS incurs.

I’m thinking about buying the 5 lot of the bare T5 5B1 placing them on Noctigon copper base from IOS. Does that seem like a reasonable idea? I see there is both a T4 and T5, which one to choose?
