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

This is a re-post from the What did you mod today? thread, where I put some beamshots of a modded Convoy S2 with SMO reflector (vs the previous with OP).


I changed the reflector in my convoy S2 (with S2+ short tube, Led4Power 4-6A driver & spring) and Convoy forward clicky switch) with Osram White Flat 1mm2 ! I liked the beam with the OP reflector, but wanted to try it with SMO.

Here are some pictures, before and after, OP > SMO!


Not sure if this is the best way to show them in gif and side by side, but I hope it works!!

Overall, the beam looks tighter as it should. I need to test it outside yet and see how it performs. Still, this is my “pocket thrower:smiley:


I have some doubts for those who installed this led under a small SMO. Is it normal to get some “rings” or at least a “larger corona” between the hotspot and the spill, or do I need to refine the placement of the gasket+reflector to reduce the artifacts?

Thanks in advance :+1:

Trying to improve the focus is the first thing to do. (a domeless led needs the reflector closer to the board, i.e by thinning the centering ring)

But if that is done well there could be another reason for rings. I put a 1mm2 White Flat in a S8, which uses the same reflector size as the S2. I happened to have 3 SMO reflectors in my reflector box of different sources, bought from Simon, or Fasttech, or recovered from another host that I made into a triple, I don’t know where they came from, but 1 of the 3 behaved significantly better than the other 2, it produced a no ringy beam and had the best throw.

So you may be lucky trying another reflector if you have one around.

It happened me with Astrolux FT03. White flat 1mm”-s very picky on reflectors. I had two FT03s and one reflector was better with 15% extra kcd than the other.

Thanks for the answer djozz! I tried it with different reflectors (different height and width), but the one I bought from Simon is actually the best one I have.
I was just wondering if the placement of the led+ gasket would be the ideal in terms of position towards the reflector.

When I look from above, I do see a small “spot” right in the middle of the LED, that I think it indicates that it well centered. But I don’t really know… Maybe it is the shape of the reflector and not the position that originates those rings… :person_facepalming:

Yesterday I tried a Boost HL in a Supwildfire host aka “Mitko thrower”.

Unfortunately this was a new version of the Supwildwire with so many dimensions off (even with stock led the beam was crap) that the build turned into some nightmare trying to fix all the issues of the host instead of checking out the new led (for example, to focus the led well it should be positioned inside the reflector, so I had to grind a mm off the underside of the reflector, which again ruined the already minimal clearances that there were already for the ledwires. Spend a huge amount of time re-shaping a centering piece to exact correct, necessary for such a small led in a big reflector! Got it finally done, with L4P LD3 driver at 6A, and with the led almost (but not perfect :frowning: ) focused and then mangaged to spit in the reflector while blowing it clean :weary: . Tried to clean the reflector with water and soap, but I clearly should redo that.
I measured the throw at 400kcd exactly (30 seconds), which is a pretty decent result (I must say that shining it down my square is very satisfactory :slight_smile: ) , but I’m sure there is more potential for this led in this reflector size.

Here are some pics:

Djozz,

A lot of work here and while it is not perfect(crappy host) it looks fairly well… :beer:
330 KCD with good spg2s42b are results I got for this light and equivalent in lux performance to B158. So your build indicates that we can expect 400+ kcd results in B158 host as well.

I really don’t know why some of you guys use soapy water for reflector cleaning? Yes I saw that is recommended several times on cpf and blf…
Anyway I would not recommend that to anyone. I would recommend LCD screen cleaning fluid and super fine microfiber cloth… It works equally well for aspheric glass lens cleaning as well.

If reflector has micro aluminum particles inside before applying lcd fluid blow the particles out with air compressor or compressed air.

Thanks for the advice for cleaning the reflector l.i. :slight_smile: I will give it a go one of these days.

Lcd cleaning fluids usually have microfiber cloth in package… Don’t use that one cause it is to rough… Leave that one for your LCD monitors…
For reflector use Super fine microfiber cloth for DSLR camera glass/LCD screen cleaning in two steps:
Spritz gently reflector/wipe with one superfine microfiber cloth and after that do another step(but without spritzing just wiping after job you done in first step) with second dry superfine microfiber cloth and it will be shinny without any flecks.

That clothes can be reused again when necessary if it will be washed in laundry machine.

Heard it, and tried it because every time I've touched a reflector with denatured alcohol Mr ethanol ruined it.

Works good. And albeit it's not essential I think distilled water helps a lot.

:-)

I didn’t have the time or the opportunity to test my Convoy S2 with the OSRAM KW CSLNM1.TG (1mm2) White Flat + SMO reflector before. This weekend I tried it and made some night shots comparing it with another “similar” tube flashlight, a Convoy S2+ with XPL-HI U6-3A and SMO reflector.
My S2 has been shown above, so it needs no further consideration.

I must say one thing: I am really impressed with what this LED can to even in a small SMO reflector and small light! Really impressed!!! I reached real illumination at about 400m!!! With the specs of this little light and reflector I believe it is something, right? :wink: (yeah you guys that use big reflectors will say this is an ant dimension, but I still like it :stuck_out_tongue: )

S2+ on the left >>> S2 with Osram on the right (it will be the same scheme in the sequence to follow, always with the S2 on the right)

@45m and 100m

@201m

@303m

@398m

I really like these LEDs! I need s2+ copper with this led. It is super awesome to have very small pocket thrower!

any one has one for sale?? Please pm me

I have a Convoy M1 build with 1mm² CSLNM1.TG nearly finished, with linear driver set at “5A” (one of the newer SST-40 drivers from Simon modified with 8mΩ sense resistor: R010 + R050 + R200). Just need to bypass the switch and solder the driver, will say something later.

MascaratumB, that is truly impressive! Thanks for the beam comparison shots!

SMO reflector ?

I finally threw a CULNM1 in my Jaxman Z1 (you know, with the nice glass lens). It's running off 13x AMC7135, so a nominal 4.94A. I might get up the nerve to reflow another one or two on there, but maybe not. I don't have a good idea for how well the Z1 handles the heat, and I roasted the CSLPM1 I had in it first. That was probably because I had something on the LED that burned up, but I'm not sure.

Anyway, it's my first aspheric, it's a glorious gosh darned pencil beam and it's just hilarious. I haven't been out at night with it yet (I finished the mod after 11pm Friday and had a busy weekend), and I'm sure my stock MF02 outthrows it, but it's my new favorite thrower. It's so damned small it will fit in a jacket pocket, especially when twisted down to flood mode. Jaxman sent a lens cover with it even, which I actually use. And just for fun, I ended up having to use a black, reamed-out 3535 centering ring for the 4040 footprint, so it projects a nice donut image of the centering ring around the square die image.

:smiley:

Even if not that important, yes. I carefully glued a 3535 gasket around the emitter, one which I had previously lapped to reduce its height from 0.8mm down to 0.6 or 0.5mm. The reflector sits quite close to the solder pads. I had to dismiss my first attempts, where I left the gasket at just 0.2 - 0.3mm and the reflector wouldn't seat properly due to it landing over the pad wires. O:)

:-)

Thanks David :+1:

I think that with a small reflector, it is indeed impressive. The beam is not straight all the time as it has a slight opening, but it makes possible to have a tube light (eventually in a 18350 version) as a “true” pocket thrower :partying_face:

Gonna have a walk with this M1 right now. Its driver pulls nearly 4.8A on high according to my power supply.

The reflector setup… don't know what to think of. The corona is slightly asymmetrical, and I see rings.

Took some quick ceilingbounce measurements, got very close to 100Kcd for my M1. I don't know how accurate is my smartphone luxmeter. I have a Sofirn C01S in case anyone wants to help getting some comparative figures. Will measure again with the help of a friend in a day or two.
