New Luminus SST-20 (3535 size)

[The_Driver1 (The_Driver)]

Future development of the maximum luminance of LEDs

Luminus now has a new LED on the site, the XP-G2 sized brother of the SST-40, the SST-20 (datasheet). Features: Thermal resistance: 3.5°C/W (XP-G2: 4°C/W, CSLPM1.TG: 2.6°C/W) two different solder profiles: => A120: XP solder profile with neutral center solder pad => B120: smaller Osram (Black Flat, Square etc.) solder profile with neutral center solder pad rated up to 3A square die (not retangular) brightness at 1.5A: up to 10.7% higher compared to XP-G2 S4, average might be…

The high-cri version ist certainly interesting!

I have a feeling we have a new throw king (when dedomed) …

[led4power]

Hardly, it should generate ~1700-1800lm (dedomed) to match black flat, and that requires 8-9Amps which this LED would never achieve.

[giorgoskok]

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 )

[Enderman]

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.

[The_Driver1 (The_Driver)]

It’s already in “full production”.

@The_Driver

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.

[gchart]

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

[X31 (-X3-)]

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

[X31 (-X3-)]

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

The CSLNM1?

It is in the newest Audi’s, does that mean full production?

@The_Driver

The CSLNM1?

The one that replaces the Black flat, not the bigger one.

[contactcr]

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.

[g_damian]

SST-20 L2 6500K is available on kaidomain for $3.19.

@g_damian

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.

[gchart]

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:

[EasyB]

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.
