New Luminus SST-20 (3535 size)

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 :frowning: 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

Nice rig Redlyne22!

If the board is a DTP board (I assume it is), the current capability and light output of the SST-20 is not impressive.

so 1100 lumen max, great upgrade from xp-g2 i guess

Not impressive indeed, if the lumen number of 1104 is accurate. Compare that to the XPG2 S4 with 1300 lumens at 4.75A.

I was hoping for XPG2-like performance but with a low Vf.

Thanks man. its no where near the level of accuracy you test at. Mcpcb is copper but not sure if its DTP. The mcpcb is what the leds came on from aliexrpress. maybe I should reflow them onto a Maxtoch and run numbers again.

I’ve seen your tests. You are great at testing LED’s. So I’m all ears. Any pointers would be greatly appreciated

For the re-test, this is what I’m thinking to change.

  1. Reflow onto a known DTP mcpcb
  2. Shorter LED wires.
  3. ? Put a reflecter on the LED ? Maybe a P60 SMO reflector.
  4. Active Cooling.

I did the test fairly fast. As soon as I wrote down the results I raised the input,not allowing it to cool. should I wait and allow the LED to cool down.

I’m almost certain if I retest I’d get higher lumens, but higher lumens is not what I want, I want to be more accurate in this re-test. Either way, I’m fully open to recommendations.
