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

Thanks. Did minor change to comment on those.
Ill let the ones from LCK-LED and LedDNA be questioned until someone have confirmed the same. I assume they are the same though…

Intl-outdoor have now gotten XM-L2 T6 3C on 14/16/20mm
They have also gotten XP-G2 R5 2B and R5 3C on 16/20mm

All added to spreadsheet.

excellent initiatives guys you all have here!
thanks for the sharing :slight_smile:
I don’t know if this is right place to ask.
is there anyway we can distinguish xml bin from the emitter physical attributes?
I’m trying to tell which of my light is T6, U2 and U3 except reading it from the box or label on the light. maybe the labelling is just not true.

Unfortunately there is no way to tell by looking at the LED, you'll need to trust that your source is reliable and not falsely labeling bins.

There are sadly no way to tell the BIN. Only a light meter could tell the difference if you have the emitters you are comparing driven at the same amps… At least, that should tell which is brighter than the other and thereby indication of BIN. Especially if you have one trustworthy emitter to compare with.

Famous name brands should be trustworthy. The majority of cheap Chinese light I would not consider trustworthy.

I think there are a few stores out there that can be questioned even for the emitters added in the spreadsheet. Im thinking specifically about several of the XM-L2 U2s that was early available. ( I would consider Illumination Supply the best source for XM-L2 U2)

unfortunate that there's no way to tell without tools.

eventhough having a light meter doesn't really can tell accurately due to the different temperature color, it can lead to some grey area. anyway this might be a concern when there is different information regarding particular product let's say label in the box, label in the manual or warranty card, label in the light itself and label in the seller and manufacture website. even decent manufacture can use box/manual/card with different description to save some cost.

I got some XM-L2 U2 1A's that have that familiar yellow glow around the center beam - obviously 1B or 1C's, but KD said they were 1A's when asked... I believe they are the Mouser batch's that don't specify a specific tint, just a grouping, and since they "might" be 1A (or 1A is the first listed), they just say 1A.

"I trust in IS", next trustworthy source is Hank for me...

Or they just licked a finger, pointed it up in the air and depending on the way the wind was blowing they decided upon BIN/TINT within the CW range. The other hand was probably used for crossing fingers and hoping for CW… :stuck_out_tongue:
I think its their way of deciding what specifications products will get. I also think their customer support work by that philosophy.
I personally don’t consider KD trustworthy of anything. Their customer support come with more false info than true based on my experience with them.

+1

When that is said. FT gets most of my money when it comes to emitters, just because of price. They seem to be fairly accurate when it comes to emitters.
TINT/BIN combo vs PRICE decides who gets my money…

XM-L2 on copper just turned up on DX. Im not sure about the dielectric layer.

Nice find Flashpilot. I added it.

This colorful XM-L and various others emitters have also been added…

Its a shame that LCK-LED did not have the XM-L2 in 3000K when I recently placed an order on various emitters. I would have bought one… If i buy more from them in the near future I will add one mounted on copper. Just to check it out…
All XM-Ls they sell can be mounted on 16/20mm copper star for 1$ extra.
I have added WW XM-L2 and done some price fixing/update to various stuff…

Also, various other small stuff have been added in the past be me an other users. Thanks to everybody who contribute! :slight_smile:

Thanks for keeping the database up to date and tidy for everyone to use. Since it seems to keep getting messed up, perhaps you should consider locking it with a password and distributing that pswd to a select few… just a thought.

Thanks. If it becomes a problem I will consider. But so far, its seems more and more people are contributing.
Small stuff I easily fix. And the larger mess that have happened to some sheets looks to be some sort of “formatting error” or something. Thanks to Scaru I now know how to easily restore it.

Just that people post links to new emitters (and MCPCBs in this thread is helpful to the whole community.

Its nice to even see people (okay one guy, so far) from CPF joining in and seeing the value of the spreadsheet. :slight_smile:

Nice Work! THANKS!

Dan.

Updated links/prices to the copper MCPCBs from intl-outdoor.

In the spreadsheet I also see that vestureofblood now sells 16mm Sinkpads… A nice option for US buyers who want fast shipping, or for buyers in general who needs 10mm copper boards.
Same good (shipping) price for international buyers too.

Updated prices for Kaidomain - $7.27 each now - not bad, but I got mixed results, some looked like 1A, others looked more like 1B or 1C.

Nice price for XM-L2 U2 (if they are U2s).
I updated the U2s from lightmalls. They are now down to 8,90, so not much lower than before… Cant compare with KD in terms of price.

For those who have been looking for a very cool white XM-L2.
XM-L T6 0D 7$ from cnqualitygoods.
http://www.cnqualitygoods.com/goods.php?id=1831

They also have other CW T6s in stock, but I cant be bothered to add them since several other stores have similar products at same prices.
I dont think that many people care for XM-L2 T6 CW? Unless its T6 0D and for de-doming purposes or something…

May be cheaper to buy from fancyflashlights (due to free shipping), but I was not able to access their site.

Try this link for FFL: http://www.fancyflashlights.com/category.php?id=7&price_min=0&price_max=0&page=2&sort=goods_id&order=DESC. They got probs, this should get you in. I've used the T6 0D's - yes, for de-doming...

Thanks…
6.9$ and free shipping
Changed previous links to that store.

Was recently a thread were a guy asked for 0D tint. Id guess there is some who are interested in that tint.

Tom E, for maximum throw and PERCEIVED brightness. What would you prefer out of these two?
De-domed XM-L2 U2 1A
De-domed XM-L2 T6 0D

Well, actually I made that choice and went with the U2 for the SS T08, but had both, so, still used a T6 0D in a resistor mod'ed SS T13, but the super T08 got the U2 de-domed and I think benefited the raw kcd numbers. Not apples to apples, but the T08 @4.5A got 210 kcd (about there?), and the T13 at 3.4A got 155 kcd.

Resulting tints are both strong neutral - don't think the T6 0D was as neutral, but that's a tough call because didn't have both mods available at the same time.
