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

What he said, This method is excellent.

The led4power dtps are nice quality! a good flat fit to the host with some grizzly kryonaut and you’re pretty well sorted.

The boost version of the 2mm? is available here but needs reflowing to DTP

I ordered from here last week but until they arrive I will remain skeptical

We have waited two years for this LED to finally become available! Supposedly the ultimate thrower LED.

Interestingly, the SBT-90.2 which became available in the meantime is a better fit for many larger lights.

:partying_face: I hope it will not be to hungry…

That “HX” from AE (YinDing) seems off. What’s with the exposed gray portion next to the die? Also, their other white flat listings have unusual markings on the surrounding white areas of the package.

I’m using their red flats and they’re legit

I would guess preliminary version of LED (is why it looks different)

I got here 2 flashlights with supposedly Osram NM1 LEDs

Both have some letter markings on top of the LED, but one of them also has a grey bar on the side (while the other does not).
Is there any difference?

Why do you think they call it LED lottery? You are supposed to scratch it off and see if you win!

/s

no idea

As contactr mentioned earlier. I’m presuming this is a pre-production or engineering sample type marking…

Another 2 flashlights with Osram, one has the gray bar, the other doesn’t.

Any specs?
The right one seems to be the CULPM1;which is the higher current version of CSLPM1.TG. There aren’t too many manufacturers around which use them

They look the same size to me. isn’t the CULPM1 the 2mm version?

Both flashlights are the same model: Manta Ray S21 with Osram NM1 LED (supposedly) - one has a gray bar, the other does not. The Manta Ray S21 uses a 2.8Amp (7135x8) driver, but the UI is sort of different (it seems to be related in terms of configuration as the Convoy C8+ SST40 ‘ramping’ driver version).

In my other set of Osram NM1 photos, one is a Wainlight C8S-G with Osram NM1 LED (no gray bar), the other is a Boruit C8 with Osram NM1 LED (but has a gray bar). The Boruit C8 and the Wainlight C8S-G look very similar (they use the same flashlight host as the Convoy C8+, but place an Osram NM1 LED and both seem to use a driver that is similar to Convoy’s 5/3-mode group driver (also 7135x8 or 2.8Amps).

you’re correct

i was thinking about this one

Wow that’s a good find! You can even buy this soldered onto various size boards down to 11.8mm for use in AAA sized lights!

CULPM1 also has a 4x4mm pad IIRC (vs 3x3mm on the CS models), isn’t that why it has higher thermal resistance?

Yes, but not on 3030, he uses 3535 and the copper boards aren’t dtp

BurningPlayd0h, according to my wisdom a bigger footprint equals lower thermal resistance; or it should.

Kaidomain has both 3030 and 4040 DTP boards for sale, check here:
