As found at Mouser. I do not see groundbreaking specs, but the output seems good. I hope to do a test if I can get hold of a few.
Thanks for taking the time and effort to do that! Looking forward to your test results.

I see Mouser has some second generation Oslon Square (GW CSSRM1.EC) too. Perhaps you can also try that djozz? 
sounds interesting! what was the last popular ssc led?
The last popular SSC emitter. You can find listings on DX for P7 lights, don’t know if any are still available. The P7 was a popular emitter for M@G mods.
Fonarevka.ru had a thread about this led already back in August. It seems that the claim to fame of this led is that it is cheap, and that the performance is not as good as a top bin XP-G2 (they are not 'hotbinned' at 85 degC).

The price quickly becomes a sore point if you have a system that needs many leds anyway. Low cost to add a few more instead of top binned Cree that comes at a premium. Makes sense.
Gurthang mentioned the P7 which was the multi-emitter package. P4 was the single emitter variant using the same die. Both packages used the same Cree provided EZ1000 die used in the XR-E/MC-E. The differences were a matter of the details of packaging. SSC hasn’t really been in the competition for what we consider as flashlight LEDs since Cree made the jump to the XP-G/XM-L. It’s nice to see a new offering even if the competitive point is mostly price… this is Budget Light Forum.
I am interested, especially in the 90+ CRI version , as you suggested. Now get hold of them..
The OP is a seller offering the LED and claiming it to have same performance as top bins of XP-G2 and Nichia for much cheaper price. One of the members replies that at 350mA it’s 162lm at 25C, and 142lm at 85C which is lower than top bin of XP-G2.
(From Cree datasheet S2 is 168lm and 148lm)
