Looks like another variant of a copy of an XP-E emitter.

Hi all,
I bought cheap “GENUINE XHP70” led lamp from aliexpress (as starting point to my own project with XHP70). Here are pictures. Is this genuine led ? i don’t think so. Is it bright ? yes. Is it good ? I don’t know Big Smile

Definitely not a XHP70 (or 50) in any way. must be some kind of new knock-off, or just a odd-ball un-branded LED. The dies size look close to that of a CREE MC-E emitter, but its not one of those either.

i recieved genuine XHP70.2 XHP70B-00-0000-0D0BN40E5 from farnell. By comparing these two there are few major differences :

1) light emittors are up to 3 times bigger than chinese
2) “dome” (i don’t know exact name) is not that clear as is on chinese copy
3) you can not see supply traces on support pcb
4) there is one dot and one rectangle instead one dot
5) there are almost invisible spaces between emittors. Chinese has huge gaps.

I am posting this question here because I didn’t want to create a separate thread just for this question. This emitter is from a genuine CREE spotlight, and I can’t find any information on it. My first impulse was to call it a CXA1603, but I can’t find any information on that emitter.
BTW, I once read somewhere a couple of years ago that CREE was planning on using non-CREE emitters is some of their light bulbs to keep cost down. So i suppose it is possible that this is a “fake” CREE emitter in a genuine CREE light Sick

Does anyone know what this is????

Looks like a Cree CMA series LED, similar to this: > https://ca.mouser.com/ProductDetail/Cree-Inc/CMA1840-0000-000N0H0A30G?qs...

DBSAR, thanks I had never heard of the CMA series
http://www.cree.com/led-components/cma
But this one doesn’t match up with any of those.
Diameter of the COB is 14mm while the metal substrate is 18mm. Measured voltage while running is 67.8V
Also they are calling this a high CRI light.

It would be interesting to see how far one of these can be pushed. As it is driven now it is rated at 850 lumen.

Maybe it was a special version/model of the CMA series they make for only use in their LED light bulbs running on the 120 volts line-voltage, (with a voltage reduction circuit) and not available as a separate component? difficult to know in that case.

Well after searching and searching I have concluded that this emitter is not made by CREE but rather made for CREE using their patents. I suspect that CREE licensed the technology and outsourced the manufacturing to an outfit in CHINA.
Bet THAT’S never happened before, right? Wink

Here is the UPC code and statement Made in China and Manufactured for Cree, Inc.

If that is true, then is this a “fake” Cree emitter?

I don’t think so, its could just be called a Cree emitter made by someone else Smile

This is an example of the first Cree light bulbs that I know of. This first iteration, like other brands, had heavy ribbed heat sinks at the base for long life (23.8 years) LOL
Later on Cree came out with the cheaper to make “4Flow” bulbs that were vented but had no sink

These older bulbs were actually made by Cree, the newer “4Flow” were made for Cree

These do look like another variant of either latticebright or other fake/clone of XM-L2 LEDs.

Thinking the same…

This is genuine Cree led.

This is unknown.

As far as I can see the Cree is a little bigger and there is no this little square in the dome, also grey area around the dome on Cree is like OP reflector, and on unknown is like SMO.

If it is Lattice bright than can be XM2 or XF2

The fakes all seem to have a smaller die, and most have square bond wire pads where genuine Cree LEDs have round pads.

This is maybe a better picture it is from Convoy S2+.

You think this 2 wires that are touching the LED ?

The 2 bond wires on the side of the LED die is the most notable indication for most of the fake ones, the real Cree ones have the round pads like the pic above.

Yep, understand.

Does anyone here find a way how to determine differences from genuine Cree led series like XM-L2 ?

U2, U3 and U4 for example how to know what is about or it is not possible ?

I have a picture I would like to post, but for goodness sakes I can’t figure out how to add a picture. I’m in my late 30’s, not ancient lol. Can anyone help? I don’t have a “url” to post a picture. Why can’t I simply copy and paste?! Lol

I'm 61 and have posted 100's, maybe 1000's of pics here, of course I've been programming computers for like 40+ years smile

I use "Advanced Post Editor", then click on the top most "Insert", choose Insert/Edit Image. Then in the Source field, you need to enter a URL directly to a picture. Here's one to use as an example:

 https://oi1054.photobucket.com/albums/s496/TomE2012/Custom%20Mods/P1030101_zpsac2bbr10.jpg

In the inserted image, it will look like this:

I reduced the size from 1024x768 to 300x225 in the "Dimension" entry. The tricky part is to find a hosting service/server that you can get url links from. I use PhotoBucket in a paid for mode though. Lot of people here use imgur.com, but I find it somewhat hard to use.

I am unsure what those are, they look like a cross between a XTE Cree and the odd-ball LEDs found in some Skyray King clones i seen, as most of the cheaper random-branded lights have been using the knock-off Latticebright ( and now other random unknown LEDs, its difficult to tell when it comes to buying unknown brand lights.

Ok. Your meaning Cree XTE? It does look like the picture in that thread. I’m about to buy 60 of these and I just want to make sure they are the real deal. So it can be a Cree and not say Cree?
