OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm²

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! :crown:

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 :beer:

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

OSLON and OSTAR are both osram branding terms

@ 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.

Hi, guys.

i`m reviewing Olight Marauder II

and this flashlight use dozen of OSRAM KW CULPM1.TG for floody light

i`m quite confused about logic of this choice, as i used to treat OSRAM KW CULPM1.TG as totally throwy LED.

what kind of advantage can such set of LEDs can give comparing to like, XHP50.2?

i`d understand if they put it for throw. but they chose P6 instead (which is another question).

could anyone who , unlike me, know things about LEDs, reveal this mystery and help to make my review more informative.

P6 is not CULPM1.TG, it’s a cheap domed Osram LED that is ugly from my experience.

The review I saw showed only CULPM1 used in the center LED not the 12 outer ones so I think you may be mistaken?

i mean P6 for central light and CULPM1 for throw ))

but thanx. what you wrote means logical. question is closed.

Olight should mention what they use here.

Why is nowhere information about the CCT of those Osram emitters? I really would want to know how much K their color temperature is…

I want to replace some green SST-20’s on a Astrolux MF01 Mini for the CSLNM1.TG do the LED pads align?

Will they survive the FET driver on the MF01 Mini in the first place? Their Vf is rather low.

I think it depends heavily on how hard they are driven. I can say my personal experience is that the 4040 pad versions are warmer (looks like ~5500K) and have a higher duv/more green tint than the 3030 versions, of which all of mine have been 6000K+ and very rosy.

You can put the 3030 CSLNM1 on a 3535 pad but it’s a tight enough fit that tolerances means it may not work on some 3535 pads. I would assume though it would either fit all pads on the same board or none at all, i don’t think it would be a case of it fitting only some.
It’s also a bit fiddly to align them to the pad which will slow you down when doing multiple reflows at the same time so i consider anyone who can do many at a time to be a superstar :smiley:
