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

Datasheet Vf curves are usually given for some typ. Vf bin, what I see in real life is CSLNM1 and CSLPM1 come in lowest "15" Vf bin, while CULNM1 (my samples) are middle "B5" Vf bin.

This means you can't really make predictions using datasheet numbers, Vf values of "15" binned CSLPM1 are considerably lower that what datasheet suggests.

Another picture, rescaled each curve so they start at the same point.
This way we can see clearer how does performance scale with current, abstracting away efficiency of individual LEDs. Here some samples are clearly better than the others, such test hides this difference.

The curves for Boost HL nearly merge into one, that’s good…much better than I’d expect…this hints at very good test setup.

I would expect Boost HL and White Flat to score pretty much the same at low currents but pull ahead later on.
That’s not the case, they start the same, White Flat is actually better at middle currents and Boost HL pulls since 4A (which is about 6.5 at the X axis).

I would think this win in the middle to be a test fluke but the consistency of Boost HLs makes me wonder it’s actually real.
I don’t know and I don’t have an explanation.

Thanks for these graphs Agro.

Which numbers did you use for cslnm1.tg? You have mentioned Enderman got 1115 lm, I got considerably lower max. (950~980lm) for the same 6N bin, djozz' numbers seem to be also <1000lm from last test.

Also it's worth mentioning that 6N bin is second highest datasheet bin fom cslnm1.tg, while 5Q bin is second lowest datasheet bin for culnm1.tg.

We don't know what bins are practically possible, but we can realistically assume culnm1.tg could come in one bin above 5Q.

I used to use your lower numbers because you highlighed them.
But since you mentioned getting 980 lm a couple of days ago I went with that in these 2 charts (though in the latter it doesn’t matter as it’s linearly scaled anyway).

Have they been put up for sale yet? Or already sold out?

Added to site, sorry for delay, busy as usual:

CULNM1.TG

I’m surprised but quite large price hike.
It is the throw king and for quite a few uses - well worth the price. But I’m still wondering.
Is it that Osram charges much more? Or is poor availability the reason? Can we expect the same hike from Boost HX?

Price of reels is significantly higher than white flats, and reel is 2000pcs, I guess higher price is mainly caused by the fact that LED is not mass produced.

I see, thank you. So…you’re not short of them yet :slight_smile:

This is going straight into my L2. It should centre a lot easier than it’s 3030 brothers. With the Luxeon V’s, I reamed a 3535 gasket with a 5.5mm drill bit and it fitted perfectly. It should work with this one as well….

I didn't buy full reel, far form it, I had ~190pcs before sales started, and I don't know when/if I will have new ones.

I secured 3 pieces, but am not sure yet where to apply them.

Thanks l4p for making these available :slight_smile:

Good idea with the drill bit. I'll have to remember that one. I have a very cheap wood reamer I've been using, but it's slow and I have to keep stopping to measure.

How do you guys clamp the gasket to stop it from moving?

My method is not wise but I just hold it in my hand (thumb and index) and do short bursts with small variable cordless drill

:open_mouth: You have stronger and/or more laceration-proof fingers than i do!

I think it might be easier because I use a step bit so it’s only ever taking off a little at a time.

Looks like Maxtoch, in addition to sourcing green and red “flats” also might have this 4040 LED in their latest thrower now. The text on the chip sure looks similar.

But proportions are not, the yellow part is 1/3 the length of the package. This looks like 3030, CSLNM1.TG.

So using the 4040 version, they may get it at 1 Mcd.
