The black flat successor KW CSLNM1.TG will not have any of the problems the black flat does, such as non-neutral thermal pad and cut out corner.
It’s already in “full production”.
The CSLNM1?
Too bad that the two supplier offers only the SST-20 6500k version, which is for a me a litle too cold.
Cold, yes. Colder than I usually prefer. But at least if it’s like the SST-40 (as is expected), then it should be a pure white, not blue or purple. I put a few dedomed SST-40’s in Convoy L2’s and actually don’t mind the tint for a thrower.
I pulled the trigger on the Aliexpress listing last week. I can’t wait to see how they perform sliced / dedomed - should be good. Not that I really needed 10 of them :person_facepalming: but at less than $1 each, oh well
Just ordered 3 of them.
I agree with the last comments, I don’t mind cold white in a thrower.
It doesn’t need to produce 1700 - 1800 lm.
It’s not competition to XP-L HI but to XP G3.
Around 1000 lm would be fine, especially if it has low Vf and is dedomable.
So, low Vf and above 200 lm per square mm, yes please.
Cheers,
Nico
I’ll try a sliced one in my Amutorch JM70 (now a dedomed XP-L) when I get them. If it improves throw I might test it in my Olight M3XS…
Will definitely update here
It is in the newest Audi’s, does that mean full production?
The one that replaces the Black flat, not the bigger one.
I’m sorry but a SST-40 6500K is not pure white. With a reflector you can easily see plenty of blue and purple spill. No doubt it’s a great emitter but I think this ‘white’ tint assumption is way over hyped.
SST-20 L2 6500K is available on kaidomain for $3.19.
Cool, thank you for reminding me. I just purchased 5 sst20’s from kaidomain. Let’s see if it gets here before the 10 I ordered from aliexpress.
I’m new to this led game. But from the relatively small amount of knowledge I’ve learned all signs are pointing to a the next rockstar LED.
I will test and report back to this thread. Ill do fet with a brand new C8 sofirn and fet with ut02. I’ll start with old pani laptop batterys then work my way up to a Sony vtc4a.
I also have 10 coming from that AE listing. I had been waiting on a response from KD, then just grabbed the AE after not hearing anything for a week or so. Of course KD listed them like the day after I pulled the trigger :person_facepalming:
I will probably order a few. The low Vf and (probable) high luminance dedomed make it a winner. The sofirn C8F triple might be a good match for this LED.
Yeah, the bigger one is the P, the smaller one is N.
Unfortunately no place has them in stock yet 
500 min order.
When buying 500, what’s the price? Just trying to get some indication of what we can expect…
It doesn’t say, you need to ask for a quote.
Also it’s actually 2000 min not 500, the 500 is for a ‘dummy sample’, whatever that means.

I will look into…
I got my 10 SST-20’s LEDs from aliexpress yesterday, so today i rigged up a DC-DC buck driver powered by 2 sanyo GA,s. Measuring Volts with a cheapo MM. Measured amps with a Uni-t clamp meter. And lumens with a lumen tubes I copied off of VOB’s utube video(that has been surprisingly accurate).
The lead wires are very long, so I’m sure voltage sag is happening.
Here are my numbers. Take it with a grain if salt, or boulders of salt.
Lumens started to flatten out at 3.67 vf,and 5.61 amps resulting in 1104 LUMENS.
I pushed it to 3.82vf and 6.41amps but zero gain or loss in lumens. Not sure what this means. But LED seems fine
