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

Although I don’t do some powerful throwers as you folks, I like to try some things.
Last weekend I picked my Convoy S2 w/ Osram KW CSLPM1.TG 2mm2 (w/ led4power driver set on 6A,SMO reflector), my EagleEye X3R w/ OSRAM KW CSLNM1.TG 1mm2 (w/ led4power driver set on 4.5A, SMO reflector) and my Convoy S2 with XP-L HI U6-3A+ (w/ 8*7135 Biscotti driver, SMO reflector).

Went outside and compared some beams!
Convoy S2 vs Eagle Eye X3R vs Convoy S2+

Convoy S2 vs Convoy S2+

Convoy S2 vs Eagle Eye X3R

The beam of the KW CSLPM1.TG 2mm2 (W2) is definitely wider than the KW CSLNM1.TG 1mm2 (W1), so it doesn’t do the pencil beam. Still, it is very intense I am curious to see how it would act on a zoomable flashlight like the Odepro KL52.
Do you consider it would be a nice option?

The EagleEye with this led (W1) is still a nice pocket thrower, as I previously shown here: OSRAM CSLNM1.TG & CULNM1.TG 1mm², CSLPM1.TG & CULPM1.TG 2mm² - #956 by MascaratumB

Very nice MascaratumB! Lot of effort here :+1:

Yes it would be good in 50mm aspheric but only with precoolimator lenses. I think it is more suitable for smaller aspherics smaller than 40mm.

But for playing why not? It should throw around 400 kcd if you decide to mod it.

Just tested the Osram KR CSLNM1.23 Red and it maxes out at 3.5A which is disappointing.

2.8A - 233 lumens
3.15A - 240
3.5A - 250
3.8A - 240

I will add that I’m not using a dtp board so maybe it could be pushed a little harder

Thanks for posting the results. Any idea what Vf was at those levels? Thanks

I wouldn’t know. I just used my lumen tube each time I added an AMC7135 chip with a fully charged 30Q

I don’t know how to measure vf

:sunglasses: I think you disappointed Osram KR CSLNM1.23 Red with that.

You got to know that dtp board boost performance in some case for more than 100%

Cheers :beer:

I might have to get some of Convoy’s 3030 boards and give reflowing a go now that I have the correct solder paste.

Ok. Put as thinner layer of solder paste as you can.

Thanks for the tip

While reflowing tap the emitter with a cotton bud Funtastic, this removes excess solder.

I’ve done it before, but this certainly sounds better than my finger.

I’m guessing they’re not DTP, how do I tell between them?

A DTP MCPCB, also or better known as thermoelectric separation bla bla bla at the other side, is expected to show electrical conductivity between the thermal pad and the back of the board.

Is there no way to tell by looking?

Yes there is if you know what to look for. I'll use a few examples:

The left board type I bought once, it is not DTP and can be seen in the substrate. The thermal pad seems like a track which is floating over a dielectric layer, pretty much like both anode and cathode tracks. The right board stinks too, imho.

The above are DTP or thermoelectric separated boards (bought and have both). Notice the outlines around the thermal pads, they're sort of window shaped, profiled strictly around the thermal pad and the contact points. Being DTP it does not need to be any bigger since it is not a track whose surface matters like in the previous examples, i.e. it is the whole board core.

I bought fairly priced ∅20mm copper DTP boards once from here: https://www.aliexpress.com/item/32894842920.html

Taking a look,

the window around the thermal pad can be spotted.

Much appreciated.

Just as I thought when I compared to KD’s mcpcb. Confirms that mine aren’t dtp for the Osram red, I’ll reflow one to the KD board. It’ll be great if I can drive them harder.

They’re currently on 3535 so using 3030 may improve too

I was going to buy Convoy’s newly added 3030 boards but can’t tell by photo if really dtp?

I really doubt Simon has any interest in run-of-the-mill boards. Had to look: 20mm DTP copper board for 3030 LED / for osram KW...

Pretty explicit.

What he said, This method is excellent.

The led4power dtps are nice quality! a good flat fit to the host with some grizzly kryonaut and you’re pretty well sorted.

The boost version of the 2mm? is available here but needs reflowing to DTP
