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

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:

In the absence of led4power (hope they're back sometime), some way or the other we now have access to all 4 White Flats. The thread should now be renamed to

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

or maybe to

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

Hope Mr luminarium iaculator notices. Is someone going to test the Boost HX? The 2mm² WF is more surface to power constrained, this means the Boost HX should obtain a higher gain than the HL. Sent a PM to djozz…

I did seen and changed… :+1:
I still can’t remember those Osram emitters… It is to complicated to me. Letter and number dizziness :weary:

P.S.
First post of this thread requires re-editing with all relevant data. Thread is hard to follow and maybe it is better to read it backward > forward direction.

Can someone please check my below list for white, red, blue, and green to see if it’s correct or missing any

Trying to tell Simon what I need

This is the reply I received from Simon when I asked for confirmation that he had CSLPM1.TG, not CSLNM1.TG

I’m really not a fan of the way Osram has assigned their part numbers

List I have

White - KW CSLNM1.TG - 3030 (1mm²)
White - KW CSLPM1.TG - 3030 (2mm²)

White - KW CULNM1.TG - 4040 (1mm²)
White - KW CULPM1.TG - 4040 (2mm²)

Red - KR CSLNM1.23 - 3030 (1mm²)

Blue - KB CSLNM1.14 - 3030 (1mm²)

Green - KP CSLNM1.F1 - 3030 (1mm²)
Green - KP CSLPM1.F1 - 3030 (2mm²)

I just want to send this to Simon

3030 variants

4040 boost variants

By the way, djozz told me he'll be reviewing the Boost HX for sale @ Shenzhen silver ingot Technology Co., Ltd.

We'll see. djozz told me he received a Boost HX sample way back from Hank, and it performed even worse than the 5P bin CSLPM1.TG he reviewed from Neven (led4power) back then (1480 versus 1530 djozz lumen), despite reaching a higher maximum current at 9A as expected. This means that CULPM1.TG probably was some ugly duckling pre-production sample or God knows what.

Hope those CULPM1.TG emitters are some decent bin, 5P minimum.

One question, how to tell which way I reflow these leds for their polarity? Twice now I’ve got it wrong.

Reply from Simon

Just thought I’d share in case anyone wants some Red or Green from Convoy since it’s not listed on the store

I hope this could help.

!

Appreciate the help.

I thought I did follow the diagram with the indent but must have rotated it last minute

Cree also uses an indent in the thermal pad often, facing to the anode.

In the case of these Osram emitters, their thermal pad indent faces to the cathode.

This is the reason of your problem, I'd say. I've reflown many types and brands of emitters, and this is what happens with presumptions.

Lol you are absolutely correct!

“Something, something bigger number better” was basically my thought process :person_facepalming:

I hope, if he is going to stock the CULPM1.TG (“Boost HX”), that he will also start stocking 4040-footprint centering rings. Would be awesome for my Luxeon V emitters…

1mm2 underwater test :slight_smile:
Compared with XM-L2 and later with XHP35HI (70mm reflector)

That is something new :slight_smile:

I am not diving and I think you are very brave. Hope that some manufacturers will have zoom underwater light cause it would be far better than reflector based lights for diving. On video when you have to inspect something up close on 1-2meters from your diving mask beam of reflector light is just to intense. Wide flood mode of zoomie light would be perfect for such situations…

Zooming in a waterproof dive light would be… difficult at best.
