Really good news! The only downside is that I already purchased a 86 mm OP reflector for a planned XHP70 mod. Now I better should have gone SMO, I think…
I don’t think a op will do bad with this new emitter. I guess I don’t understand why it would. It doesn’t now. I guess I don’t understand how it would act any different then a xml2, or xpl in a op because the dies are a little closer together. I would think it would give the beam pattern people seek from op and give the distance people want in a smooth. Am I missing something?
Speed4goal, you are absolutely right, OP is not bad at all. But for further reach I should have bought a SMO reflector. Should have made that point clearer, sorry.
Nah no one is wrong but basically with this new style XHP it will be more suited to using in an smo reflector then the standard XHP. There should be no donut hole with the updated version. The die should be more uniform Maybe making l throw better who knows.
70.2? It will be just like the XP-G3, L.2 and 50.2 High Output High Heat No throw! These emitters from my experience are not that great in flashlights, well not for my purposes any way, I like a big beam, with down range grunt, not really a fan of just out put, flood with out throw. Did not like the 50.2 J4-1A in my L2 at all, crummy hot spot yellowish gold corona, and it got worse when I shaved it, now this is comparing it to my other L2 similar build and tightly shaved “old” J4-1A emitter. So I’m not bothering with the new 70.2, I’ll keep my stash of (10) or (8) now XHP70 P2-1C emitters guarded carefully!! :+1:
Want more throw de-dome the old XP-G2, XP-L, or even the XHP35/50/70, (not just shaved) you can’t do that with the new emitter’s! I have tried!
I’ll live with the minor artifacts of the “old quad die” emitters and the ability to de-dome them for more “throw’ any day!!
With all this extra output, manufacturers need to concentrate on better heat sinking. I find high output lights rather pointless if they have to stepped down quickly to avoid over heating.
Hmmm…
At some point some professional markets will want to have modern LEDs that can be used in pure throwers, like search lights, don’t you think so?
I find it quite strange actually, that the developments in LEDs are apparently going in a different direction.
Matter of time maybe.
Interestingly, Led Lenser has this feature. Press and hold for 130% output. It’s barely visible compared to 100%, though I do like the idea of this feature for more powerful lights.
I extrapolated the two V vs I curves and for the 6v emitters, reaching 12 amps will take approx .75 to 1 volt less on the 70.2
Running 2S direct drive won’t be possible anymore due to extremely high currents at 7.4v that would kill the LED instantly.
Although 3S on a 12V emitter will be excellent for direct drive.
Unfortunately I don’t think running 3S on a 12V emitter will work. The XHP50.2 forward voltage is consistent with it being four XPG3 dies, so I’ll assume the XHP70.2 is four XPL2 dies.
From Texas_ace’s test of the XPL2 the forward voltage at 6A is 3.56V. In a 12V configuration that is 14.24V. 3S voltage is just too low to get good high current.
