Did not look at the prints… does it have a neutral thermal pad?
Always nice to see new LEDs showing up.
So, who’s gonna test them? 
Yup, and a decent size. Like I mentioned, the footprint is nearly identical to the XP-G3. Technically, it’s offered in two footprints: A120 (main size) and B120 (smaller pads). Click for larger images.
Luminus SST-20-W A120 footprint:
Cree XP-G3 footprint:
Edit: I see that the dome on the SST-20 is smaller than the XP-G3: radius 1.3mm vs 1.53mm, respectively. Which makes me wonder if it has a small die? Also, it looks like it has a similar structure as the SST-40 (that is, not a flip chip design) which is reasonably good news for dedoming prospects. Now to find a vendor for these…
I got a good feeling about this new sst-20, simply going off of the success of sst-40 (performance, not cri) This might be our next holly grail!!!
And so has anyone thought of one of these in a GT or it’s equivalent? 
Data sheet indicates up to around 4A for some 1200 lumens or better, that’s feasible to stuff under a massive reflector. Worth looking into…
I’ve searched around the usual vendors and haven’t located any. 
If someone finds some, please chime in!
Pushing the new SST-20 to 9A to replace this one? :smiling_imp:
@gchart:
A small die size would be nice, I still have a quad Maglite with Seoul P4 LED’s :person_facepalming: who is waiting for small die LED’s.
The high-cri version ist certainly interesting!

I have a feeling we have a new throw king (when dedomed) …
Hardly, it should generate ~1700-1800lm (dedomed) to match black flat, and that requires 8-9Amps which this LED would never achieve.
Black flat is kind of a weird led to work with , so even if performance is 15-20% better than xp-g2 it will be awesome 
Osram LE UW Q8WP is awesome from my point of view (same performance as OBF but double lumens) but costs 10+$ per led , compared to the 1$ of sst-20 ( link )
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
