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
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:
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?
Thank you for your observation. I’m an amateur at identifying fakes. I’m about to drop a couple thousand dollars on lights and don’t want to be taken for a fool.
Very Helpfull thread,thanks!
have some old XM-L same package as original and bond wires
but die size a bit smaller than the authentic
will post photos soon
Looks fake to me. The substrate on that is white, but on a real XM-L2 it’s black. Even the fake emitters getting decent so as long it works fine I wouldn’t worry about it being genuine or not.
I was curious so I bought a XM-L T6 on a starboard from digikey (shouldn’t be fake right?). I installed it into the flashlight and guess what? The T6 was about 160 flux while the U3 from the light was about 200 flux from about 6 feet away. So I guess these are either real or very good fake.
Is it possible that these LB’s are actually using CREE’s chip, but has worse implementation (i.e. lower quality substrate, lower grade gold wires, worse quality phosphors, etc.)?
I also have a gut feeling that LB may be cutting corner by using the blue LED chip meant for XP-Gs in the XML-like body and try to pass it off as XM-L. Of course, that results in lower overall efficiency.
