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

I have this one in C8+.
If you shine it on the wall you notice that led is rectangle and not square but I also have the one you mentioned just didn’t put it in the host.

Is 6A for CSLNM1.TG too high?

In a flashlight build almost certainly yes. Led4power found a maximum at 6A but it was a bare led with maximum active cooling. My bare led test did not even find 6A max but 5A.
So my best advice would be 4.5A, in a very well cooled build maybe 5.

Btw, see the OP of this thread, interesting read.

Thanks! I need to add a lot of resistence to get down to that

I’ve found no detectable gains after 4.5amp for either CSLNM1.TG or CULNM1.TG in a flashlight, neither turn angry blue nor do they get any visibly brighter to the eye either IMO you’re just wasting amps after that point

There maybe a VERY TINY increase between 4.5 & 5 in a chunky host like the L2 with a CULNM1 but im not sure if it is just wishful thinking on my part

A lux meter may say different but you certainly won’t see it with your eyes

Edit: Having now taken some lux readings it appears i was incorrect while CSLNM1.TG does not really gain beyond 4.5-5A CULNM1.TG definitely gains up to 6A

Thank you, need to go with a battery that can add more resistence I think. I’ve extended the wires considerably and went with a longer spring and it dropped some but not by much.

Is it common to go with a 22-24 guage wire from driver to mcpcb to get more resistence?

What driver are you using?

MTN-17DDM

You could add an actual resistor in the circuit. I never used them yet but I bought some 2512 resistors for that purpose that can be glued somewhere inside the driver cavity with arctic alumina adhesive. Link.

Im not certain but you maybe able to turn that down a little . could be worth dropping them an email

Edit: just looked at the manual and it looks like if its attiny13a you can program custom levels

Ah interesting, they are at25. I’ll keep mucking with resistence then, thanks for dropping in!

We really need to find better names for this leds, when you say XPL HI 4B you know exactly which led is that but CSLNM1 and CULNM1! are we talking about whit leds, green!!!

Generally they’re known as ‘white flat 1mm2’ and ‘white flat 2mm2’

White flat 2mm2 is CSLPM1.TG, and was not mentioned above!
CSLNM1 and CULNM1 are both 1mm2 if I am not mistaking!

CULNM1.TG is a higher power version of CSLNM1.TG (3.2A vs 3A) its still 1mm2 but they are now discontinued and getting tricky to find. I’ve also not been able to find them in the higher bins only 5q which im not convinced is better than a 6n CSLNM1.TG.

CSLNM1.TG 6N at 3a makes 840 - 945Lumens
CULNM1.TG 5Q at 3a makes 710 - 800Lumens

But CULNM1.TG can stand higher currents when overrun , there are detailed tests on the start of this thread.

I’d really like to get my hands on some CSLNM1.TG 7N’s or CULNM1 6QF’s if anyone knows a guy please drop me a message :slight_smile:

Drat, it even confuses me.

Maybe we should mention the footprint when talking about white flat.

Do they all have the same power requirements?

The 2mm can handle more current and performs best at 8~9A. the 1mm performs best between 4,5~5A

As said, the 4040 version can handle more heat because of its surface.

8-9 you recon ?? mm ok i could only get my hands on a 7a 22mm driver, i have it in a Z1 host and it gets hot real fast, and also in a L21A host though i have yet to take it out and compare it to the regular 1mm version

I think led4power reopens soon i will grab some of his beast drivers…

I have also ordered some of the Green 1mm cslnm1.f1 these are significantly more powerful than the regular cslnm1.tg white flat and even more powerful than Culnm1.tg, im not sure what the Djozz drive figures are but just the bone stock figure eats the others alive

stock drive 4000ma @ 1450lm

You can bet your A* im dropping one of these in the Crelant with a 5a driver the day it arrives :slight_smile:
