Shoot, I ordered too soon before the bare led was listed. Neven, could you change my order to 6 bare leds, no boards (should be about the same total price), or should I do a request on your website?
Blackie did 937 lm on a bench, this does 980 on a different setup. So it may be actually worse, but more likely it’s a bit better. Don’t expect big gains though.
Yeah I was thinking the same thing. I ordered 3 but wonder how to actually drive them properly. To add on top of this, I’d like to run them in a 15mm host. I guess 5x7135 is my only option since FET kills it instantly?
@led4power just sent you an order change request, didn’t see the reflowed versions somehow.
You could get the LD2 driver from Convoy store or Fasttech.
All parts on 1 side, 3 modes 3 Amperes CC FET driver.
No PWM.
Resistor mod possible, drive this Osram at 4 - 5 Amperes.
Yeah, they give the chromaticity coordinates but i’m not able to look up what it means in Kelvin.

It’s probably cool white…
Yes… I am happy(well if I consider I am not that happy but this is life) to announce that Good old XP-G2 S4 2B is beaten!
So real life test was done with same flashlight in direct comparison with XP-G2 S4 2B dedomt (picked) vs new Osram non picked…
Test showed that at only 3.3-3.5A draw it had same performance as g2s42bdd at 4.8A (yes you heard that right). So if someone goals for runtime just bring old forgotten linear drivers in function with new Osram emitter for a lot longer runtime then we are used to :+1:
I would not hesitate to use it on single cell FET drivers also… Yes… But only with low current cells like LG BD118650(tested on that one) or those Panasonic or Sanyo GA.
It will pull around 5.5A on low current 18650 and more than 7.15 on Samsung 30q so beware since it starts to loose performance on more than 6A.
It is robust… I tortured it for 2 minutes with Samsung INR 30Q on more than 7A current draw… It does not go to angry blue or something like that. Acts normal but with lux drop…
You will like it, although some may have problem with re flowing cause it is not perfect fit to XP board but since L4P have reflowed versions on his DTP’s you can just order plug and play product
BTW did I said that L4P DTP is better than Noctigon on single cell FET driver lights? Yes it is! Constant 4.7-4.8A performance for XPG2S42B DD while on noc same emitter pulls “only” 4.3, 4.4A… But only in that configuration… In any other they could perform same.
This are test in well known hosts:
Brinyte B158 430kcd!
Mitkos super thrower 430 kcd!
Copyfire 50mm glass aspherical lights 300kcd!
What to say now? :question: Oh yes… Bye bye Cree try to beat that
Oh to add something here: De doming… De doming? What a F is de doming? De doming bye bye
Oh I am not really that happy as I sound… Time when you needed dedoming skills, emitter cleaning skills and any other necessary skills are pretty much gone even kid could make super throwers with this emitter so that maybe means game over for some diy moddersellers like myself?
Black flat sucks if I compare it to XP-G2 cause you had to pick 1 out of 5 or 10 to beat s42b if I remember right… But it seems that with new little Osram guy we can only expect greater performance than on my redneck test
And most important:
“The biggest difference compared to BLACK FLAT is thermal pad, which is ELECTRICALLY NEUTRAL, this means you can use this LED with any standard XP DTP boards – there is no need for LED PCB/driver GND isolation!”
