I have a flashlight from Japan that uses this led and I’m just curious on what it is.
It looks really close to a Samsung LH351C but I’m not really sure.
I’m also curious on how much light I can get out of this thing.
LH351C was my first guess too, but that’s not quite it: according to this test of the LH351C, it has only one truncated corner, not two. My guess would probably be an imitation/generic.
Bummer.
At least my suspicion was confirmed.
TN3535 maybe?
Very promising! The OP’s LED has a smaller die, but this one does have the 2 truncated corners. Maybe a smaller LED from the same family.
This could be a TH3535?
Datasheet here.
The design is not exactly the same (1 truncated corner, the other corner seems to be gold plated), but maybe there were changes in production process or something like that.
It could also be maybe a Lumileds HL2X in cool white? The die size would match perfectly, also it has 2 truncated corners. Since the HL2X has not been the most widely used and some types have already been discontinued, I could imagine that they are available at very reasonable prices, depending on the quantity purchased and CCT/CRI.

If they’re still making “clones”, Latticebright might be the mfr.
Their site refused to connect when I just tried it, but…
Any specific reason to keep this LED specifically?
Are you just trying to do a low-cost resistor mod, or something more involved?
Not aware of any mainstream Japanese lights, do you have a link?
My guess is either something from Lumileds or Osram, maybe a P9?
No “P9”.
Completely different design.
It does look extremely close.
It just looks nice.
And its gonna come in handy if I get another flashlight with an XPE emitter.
