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

Thanks :slight_smile:

Can’t wait for the boost HX to come out so I can buy and test it.
I would buy the CSLPM1 but shipping makes it expensive and it will just be obsolete for us when the boost HX becomes available anyway.

Thanks a lot for these two tests Enderman, especially the one with the small collar!!! The latter is very relevant to me as I plan on having a small light with this configuration at some point in the future.
I have all the needed parts except for the body of the light. It will be a compact light that showcases what is possible with LEDs. It will also look cool because there will be a clear cylinder around the collar instead of metal.

so 1mm2 with collar is as good as LEP?
but with considerable more lumens

Well not quite. It’s as good as small LEP modules used in commercial flashlights. Much higher Luminance values have been achieved with LEP in the lab.

The collar is also a few cm wide. LEP lights can be made slimmer.

Jaxman?

No, it doesn’t need to be focusable. Something simple where the head has the right diameter and can be removed without removing the LED. Probably a 1x 18650 host.

Wow!

So sad i missed that collar deal a year ago or so…

How much lumen would one get with 1mm white flat at 8x7135 ? im thinking of s2+ with this led for a sort of tube thrower…

Only a loss of 15kcd? How about lumen loss? 500 lumens? Did you ever get s chance to put a 1mm flat in the same light? How much more kcd did you get?

You’re welcome :slight_smile:
Looking forward to see what you build!

Yeah, with a collar it is significantly more intense than the LEPs found in retail lights like the L2K, W10, W3.
Even without collar it comes pretty close to LEP performance.
But the LEPs in those retail lights are much less than theoretical maximum for an LEP.

About 700 according to djozz’s test on the first page.

Also an S2 would make more sense than an S2+ because of the deeper reflector (also use an SMO of course)

EDIT : that is not quite true, as said by The_Driver. You’ll have a smaller hotspot but a bigger corona and not more Candela.

oh i didnt know that thanks! So i know intl sells centering rings for the 1mm flat white but only for 7mm reflector hole. what should i use with a 9 mm reflector hole?

No. A deeper reflector just makes the light longer, it does not increase throw in a meaningful way. It does make the hotspot smaller though.

I just installed CSLNM1.TG in s2+. The led is driven at 4.1A and it has 32500cd throw. Not sure how good this results is but this is what i got. I must note that i did the reflow and it is a sloppy job since it is on a XP sized board.

The S2+ reflector is very short though.

Deeper reflectors also give bigger coronas.

It’s all relative :wink:

Yes, the light, that is missing in the hotspot and the spill, has to go somewhere.

The corona is bigger because the deeper reflector is narrower near the LED.
(Deeper reflector is a smaller size parabola)

so bigger corona smaller hot spot.
so smaller hot spot but not more candela because less light is going to the hotspot and more to corona?

@BobbyMk, will you take a beamshot? How is the useable range? How does it compare to the XPL-HI C8?
