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

I asked Simon from the convoy store if he could get some gaskets made for 9mm reflector hole and he said could.
(1mm² led)

What should be the inner diameter of the hole inside the gasket?

Which reflector is this for? We really need some centering rings for the Osram Flat Whites to fit the L2, C8 and S2’s. Hoop is supposed to be making them but haven’t heard anything in a month or 2. Not sure about the L2 either.

The gasket from int outdoor is for 7mm reflector.(convoy s2+ etc)
The c8 and i believe the L2 use a 9mm reflector hole.

I bought a solid tube of pom plastic and will try to make some gaskets myself. If it works out I will report here.

I talked about WF1 with Simon a week ago and he told me he will get some testing samples after chinese new year and maybe consider putting them in C8. I will help him in every way I can after my 6-7 WF1 builds conclusion and led measurements.

Sweet! Thanks. Can you communicate the dimensions of the gasket with him?

I told him to just ask me if he need any measuring. I will do it.

I would be interested in 10 or more of those centering rings. Looks like I have a few people who want me to build pocket throwers for them.

I ordered some POM plastic to make myself some gaskets. All hand work and no fancy tool avaible. Its a little to loose in the reflector but I will make some more later.

Geez, this is dedication

And a lot of skill. Nice work. :beer:

Got some good news for anyone wanting to swap the 1mm2 emitter into an MF-04. The stock isolation ring does actually focus the emitter quite well in this light. I finally got back to this light last night. I centered the emitter (trial and error when tightening the bezel. Once I got it centered, I was able to confirm focus. Atmospheric conditions are very bad right now due to extremely high pollen from pine trees. I will measure throw and get some beam shots after conditions improve. The beam is beautiful and clearly beats my BLF GT which I measured at about 1 million cd.

Has this stuff been tint and CRI tested? I understand these are no high CRI emitters, but the information still matters.

I can’t remember all of the correct reflector opening diameters, but this new listing from Richard might be of interest:

OSRAM Flat White Adapter / Spacer Ring

Anybody try one yet? He also has 1mm WF’s listed.

The tint is probably good, the older black flat was more reddish than greenish at high currents. The cri is obviously low (the only way to get max luminance), it should be stated in the datasheet. Probably around 65-70.

The xml smo c8 reflector is 7mm but all the c8’s with xpl hi came with larger 9mm holes. Im not sure about the L2…

That was way back then. Now the XM-L2 version also 9mm. I got a 3 piece batch few months ago with XP-L HI and 7mm reflector holes and different centering rings but that was one time only. All others 9mm. L2 has the same 9mm centering ring as C8.

Hey gang, I’m trying to catch up on this Osram CSLNM1.TG emitter by reading through the majority of this thread. I’ll admit, some of the info is beyond me.

I have a clear anodizing C8 host sitting around I’d like to try out a Flat White CSLNM1.TG emitter in. But I have a couple of questions.

  • MtnElectronics lists the Osram CSLNM1.TG FLAT LED as “Neutral thermal path.” I keep reading that some of these Osram emitter are mounted on MCPCB’s which need to be insulated from the flashlight body. Is this true with this setup? Or has that issue been fixed and I can mount it like any other emitter without shorting it out? Osram CSLNM1.TG FLAT LED on 20mm Noctigon DTP MCPCB
  • I would like to run this with a very well regulated driver. Djozz’s graph says 4.5A-5.5A is the sweet spot. Anyone have a US retailer that supplies that? Or is Led4Power going to be my best place to get one?
  • I may try this out in my Jaxman Z1 (Cometa) which needs a 22mm driver. What have you guys been using in this case?

Thanks for the help guys!

Black flat needs insulating. White flat is like most LEDs. No issue. Above driver configured with less 7135 will be good for Z1.

Edit: not sure if u can use retaining ring with that one so ymmv.

Thanks for the help Contactcr!

Thanks a lot for this data Enderman.

I tend to define efficient thrower LED as one that gets high intensity (cd/mm²) while retaining good efficiency (lm/W).
I asked myself a question: how does a collar affect efficiency?
Not efficiency in combination with a well matched aspheric; there the answer is easier. Efficiency of emitter-collar combo.

Collar reduces lm/W. It increases cd/mm².
Emitters tend to be very inefficient when driven to top currents. That’s especially true with Osram thrower LEDs - because they can be overdriven much harder than any other LED BLFers have tested.
If they are driven with lower current they are much more efficient.
The thought was: the top intensity that emitter achieves is a mild one for a collared one. Will the output loss caused by the collar offset by better efficincy of the LED itself?

Thanks to your data I was able to answer this question (note: I estimated lumen. My estimation ignores light that passes through collar and reflection off collar edge).

The answer is “probably no”, collared LED is not more efficient. At 0.96A your collared LED does about 56 lm/W and 227 cd/mm². Emitter alone can reach 247 cd/mm² with 87 lm/W.
At the peak emitter alone does 56 lm/W and 334 cd/mm² (awesome result! L4P measured 285 cd/mm² at 47 lm/W and djozz measured even less).
The closest point of collared LED is 45 lm/W and 387 cd/mm².

For the curious: at the peak a collared LED does 24 lm/W.
