Depends on the current output, the cslnm1 doesnt like currents over 5A.
4,5A to 5A max!
So for example, you can limit voltage/amps by using thin long LED wires. The battery is only one part of the circuit.
The old powerizer batteries were pretty good, not weak at all. I still have a couple. The W1's are pretty low voltage so doesn't take much to hit 5+ amps.
Seems like there might be a new throw king in town, and it’s DD compatible 
So are you think'n it's got better throw because the surface area is the same or smaller?
What are you using for a MCPCB?
What’s the surface area? The CULNM1 was hitting about the same lumens IIRC - and possibly higher, if I’m remembering right that someone besides L4P found a slightly higher bin
1.06mm^2 it looks like it might fit on regular xp mcpcb’s. I’m not sure about that though.
JaredM, thank you so much for sharing that data!
I need to point out that my ‘lumen’ calibration is far from concrete. I cross referenced a bunch of emitters to maukkas readings as well as a few other prominent testers and it seems within a reasonable margin of alignment. Relative values I have a high level of confidence in though.
The Boost HL aka CULNM1 may still be the king, and it has the major advantage of having a neutral thermal pad, but Osram has killed that model and I’ve never been able to source one that doesn’t come with a flashlight… These are cheap at Mouser and perform very well it seems. Centering can be done with a twisted square XM gasket or a slightly reamed circular XP one. I successfully reflowed it to an XP Noctigon the first try. Luck? Idk, not testing it lol.
For sure it’s going to be the best option for FET drivers.
With a Convoy 5A linear driver and near fully charged LG H26 (4.11V) I saw 272kcd with the HHL. Same setup went for ~237kcd on it’s best day (229kcd most recently) with the WF1. I’ve put the cell on charge and will try it DD next. Guessing I’ll see around 5A that way. Maybe I’ll squeak past 280 
Nice!
We have new discovery here! :partying_face:
That are very good news JaredM!
So we have new thrower King?
OSLON® Black Flat S KW HHL532.TK ? :+1:
Black into the lead again :laughing:
I just can’t hide that I prefer FET DD drivers and it seems this one could be the right choice for such setup.
JaredM You’re the man! 
Non-isolated thermal pad (cathode) is a no-go for flashlights because DTP PCBs can't be used.
Goal of this LED was to reduce cost compared to CSLMN1 which has isolated ceramic base (probably expensive aluminum nitride).
This LED has no ceramic base, die is attached directly to metal cathode pad, so structure is very similar to low cost mid power LEDs, that's why thermal resistance is somewhat lower, but at cost of not having isolated thermal pad.
In the other news, Osram updated datasheet for CSLNM1.TG, flux bins are "shifted" by one bin up, so 7N bins can be expected soon (until now 6N bin was on 100% of reels from my experience).
I would love to see equivalent performance in the more standard footprints. The upcoming CREE XP-P would be ideal in that respect, though I don’t think it’ll compete with the Osram’s overdriven.
For now I’m happy with these in single mode DD (basically driverless) committed throwers with forward clickies. I just replaced the WF1 in my Convoy M2 and running it DD. Seeing 91kcd in a 31.5mm budget light, which was a frigg’n nightmare to focus btw, and that’s up from 78kcd with the NM1 3030. Always wanted to hit 100kcd in this light, maybe next year? lol 
I just so recently did a build using a CULPM1.TG (HX Boost) with an 8 Amp driver (the Convoy model for such emitter - link). Using a PLB 26650 / 5000 mAh cell (measured 14.4 mOhms w/ YR1030 Battery Tester) I got 24,700 Lux (converted to ~ 800 lm) on turn on. The beam is an angry blue to violet. Tailcap draw is 7.89 Amps.
Didn’t want to push this further, I toned down the amps by using a higher IR cell - Sofirn’s 5500 mAh at 45.7 mOhms IR. Tailcap reading at 6.16 Amps and 32,060 Lux output. The beam is rather cool white but not angry. The Candelas clearly show the LED was overdriven: 41 kCd at 8 A vs. 71 kCd at 6 A.
Can’t figure what goes. Should be able to handle the 8 amps and produce some 1200 (expected) lumens. As is (w/ the Sofirn cell), about 1050 lm; bearing that I didn’t calibrate my lightbox with Maukka lights but my own which do correlate with some of the published data on the forum.
This was a test run as I planned to reflow the HX Osrams to a Sofirn SD01, a triple w/ regulated output (so I’ve been told by Barry).
Purchased in pairs from Silver Ingot Tech.
Are these poorly binned Leds?
I don’t see the CULPM1 on their AE store. Link to what you bought? And I’ve always been suspicious of the white flats they had. They have an extra weird grey printing on the surrounding silicone that isn’t on any others I’ve seen.
Edit: I misunderstood. This is the link to Convoy store:
KW CULPM1.TG BIN1:8RF-fcbB46-B5-6000
That other store only had CSLPM1.TG
This made me think they were purchased from here. More commonly referred to around here as the YinDing store.

Now that you mention it, I traced my order and the grey bar is not Osram’s. Link within pic.
They seemed legit, aside from the title “OSLON” (or “OSTAR”) which I dismissed as poor typing.
The HX boosts aren’t available but the other white flats seem to be.
Looking at the specs of 1320-2010 lumens, I had perceived it as unknown binning.
Imagine fraudsters of Osram’s. Would this be common to ‘YinDing’ ? I would suppose I could order from Simon; or would you have any other leads?
Many thanks for responding. I’ve had a few mishaps with some of my projects and this lightens my conscience.
They could have been real Osram preproduction versions or rejects that got leaked into the market, but who knows.
Simon is the only source that I personally know of that has trustworthy HX available that’s on the warmest end of the CCT binning available. Maybe Led4Power when he reopens in a few days.
Found them at Mouser.
The mouser batch is a much lower flux bin than Convoys
@ Scallywag
Thanks for the clarification. Much to digest that I didn’t search thoroughly.
Nevertheless, these duds will have other uses than my SD01. At ~6 amps they do give a concentrated hotspot, although underperforming in lumens.
Took a pic through the mic, there is a QR code. Don’t know what the greyed area is covering. Album link in pic.
